Yes, Minelab metal detectors have the ability to ‘discriminate’ between different types of targets. The discrimination feature on Minelab detectors measure two target properties, ferrous properties and conductive properties.
Ferrous properties refer to how much iron is in a target and therefore how strongly it’s attracted to a magnet. Ferrous targets tend to be trash, so can be discriminated/masked out based on their ferrous properties alone by the detector. Conductive properties refer to how well a target conducts electrical current and therefore responds to a metal detector’s magnetic field. Trash like nails and foil have different conductive properties to valuable targets like coins and rings. In this case the metal detector can make a judgement as to whether the target is trash based on conductivity.
The process for configuring the discrimination settings and the method used to indicate treasure or trash varies across the Minelab range of detectors.
The size of a search coil can influence the detection depth or sensitivity of a metal detector. The larger the coil, the deeper it detects, but will have less sensitivity to small targets. Conversely the smaller the search coil’s diameter, the more sensitive it becomes but looses detection depth.
Smaller coils are lighter, easier to control and may be chosen for their ability to negotiate difficult terrain or undergrowth. They are also an advantage in areas of high trash.
The most common coil shapes are conventional solid round coils, elliptical shaped coils and the open web coils. The main reason for the change in shape is to conform to a physical requirement, i.e. an elliptical coil can be pushed around bushes or between rocks easier than a round coil and open web coils move through water easier and are lighter. Conventional round coils are often more stable and perform better and are particularly popular for gold prospecting.
The three most common types of coil windings are Concentric, Double-D, and Monoloop. The difference between these coil types is the pattern the wire is wound within the search coil.
A Concentric coil has an inner circle and an outer circle wire winding. Its search pattern is cone shaped and can be useful for accurately pinpointing a target. Concentric coils tend to be noisier in highly mineralised ground and require more over lap of sweep for thorough ground coverage.
Double-D coils are the preferred coils for most detecting. They give a blade or chisel shaped signal that covers the ground more uniformly and once an operator becomes accustomed to the signal, pinpointing can be very accurate. Double-D coils are also preferred for their superior ground balancing ability.
Monoloop coils have one winding of wire around the circumference of the coil, which is used to both transmit and receive. The signal pattern of the Monoloop coil is cone shaped, requiring more overlapping. In extremely heavily mineralised grounds they can be more difficult to ground balance, however they tend to provide slightly better depth than the Double-D coils.
Headphone specifications are not really critical in a metal detector as their audio circuitry does not produce Hi-Fi quality sound. e.g. Our detectors frequency output range is only circa 75 -1200Hz
Our audio circuits will drive most headphones from 16 - 100 + ohms.
Audio optimisation is also very subjective as everybody hears differently.
We endeavour not to confuse our customers with unnecessary technical specs because in reality there is no honest way to determine what headphones are best for you other than to try them.
If you have a detector with adjustable audio tones, such as a CTX 3030, we would also recommend you spend some time to ensure the detection tones are optimised for your hearing needs.
There is no specific answer to this question as it depends on the target size, orientation, metallic content, ground minerals and conductivity, electrical and ambient noise in the area and etc.
However we commonly hear of GPX Series detectors finding large gold nuggets at 3 and sometimes 4 feet deep, and CTX 3030s finding coins and rings at over 12 inches.
On some detectors you don’t need to ground balance at all. On others, users new to detecting are recommended to use the Ground Balance Tracking function.
In Tracking, the detector will automatically ground balance for you and remain in balance even if the ground minerals vary. On manual ground balance detectors like the X-TERRA 305 and X-TERRA 505, you need to ground balance at the start of every hunt, and re-balance periodically as required. Always ground balance on clean ground, away from metal objects.
Smaller coils are better for trashy sites, as they reduce the instances of detecting multiple targets at once. Concentric coils are generally better than Double-D coils for this same reason.
If your detector is noisy when you are detecting, but goes quiet when you stop sweeping the coil, then it is receiving signals from mineralized ground. Perform a ground balance and continue detecting.
GPX series only: if it is still noisy then you may need to try an alternate soil/timing selection. All other detectors: if it is still noisy you would need to reduce your sensitivity to the highest stable sensitivity level.
This can be caused by a number of reasons:
With over 30 years of excellence, Minelab continually delivers the World’s Best Metal Detection Technologies, creating premium quality products for your greatest detecting advantage. Minelab’s superior technology was initially conceived through the inventive genius of physicist Bruce Candy. His quest to improve metal detector capabilities has resulted in more patents for new metal detection technologies over the past 30 years than any of Minelab’s competitors.
Strongly focused on research and development, Minelab has the largest engineering team in the metal detection industry with more than 30 scientists, engineers and technicians committed to producing the next generation of detectors.
Minelab Technologies Explained:
ZVT (Zero Voltage Transmission) creates ultra‑constant high-power opposite polarity magnetic fields, increasing gold sensitivity. This innovative technology detects gold nuggets at extreme depths.
ZVT technology goes to the NEXT LEVEL for all serious gold prospectors, providing substantially improved depth. No longer will you be limited to using either sine wave continuous VLF transmission detectors, that struggle in mineralised ground, or square wave PI transmission detectors, that can be insensitive to varying gold sizes and compositions.
Minelab's new flagship gold detector, the GPZ 7000 is equipped with exclusive Zero Voltage Transmission (ZVT) technology, developed by Bruce Candy, and state-of-the-art features, the GPZ 7000 offers the deepest ground penetration and represents the most significant advancement in gold detecting technologies in years. This revolutionary gold detector will discover the deepest gold in mineralised ground and has the highest sensitivity available to detect even the smallest traces of gold.
GPSi uses the high performance and flexibility of a u-blox GPS positioning engine to seamlessly integrate location and time data with detector settings and target information. This creates WayPoint, FindPoint and GeoHunt files that are compatible with XChange 2.
Wi-Stream uses efficient low-power digital audio transmission to achieve no perceivable audio time lag (<10 ms) from the CTX 3030 / GPZ 7000 to the WM 10 / WM 12. With multiple channel capability, this wireless technology provides reliable communication with maximum sound quality.
MPS (Multi Period Sensing) is Minelab’s advanced Pulse Induction (PI) technology that transmits pulses of different time periods. MPS also samples the receive signal at multiple time periods allowing target signals and ground signals to be separated. This effectively removes the ground signal from even the most highly mineralised ground while still being sensitive to both small and deep gold. This achieves superior depth in extremely mineralised ground.
DVT (Dual Voltage Technology) is Minelab’s advanced Pulse Induction technology that uses pulses with two voltage levels to further enhance MPS. The two voltage levels work in combination with the different time period pulses transmitted by MPS to increase the amount of power transmitted into the ground. DVT also allows more of the ground signal to be removed, further increasing detection depth and sensitivity. This achieves ultimate depth in extremely mineralised ground.
SETA (Smart Electronic Timing Alignment) is a highly complex method of matching the characteristics of individual Timings with continuous measurements from the surrounding electromagnetic environment, such as the earth’s magnetic field. This gives the advantage of improved detector performance through the complete removal of noise signals. The sensitivity across all Timings is increased, therefore SETA allows more gold to be found than any other metal detector technology.
MPF (Multi Period Fast) technology incorporates extremely fast Pulse Induction switching between Transmit (Tx) and Receive (Rx) detector signals. Therefore minimal residual transmit signal is present during the receive cycle, enabling clear sharp detection of very small gold.
VLF (Very Low Frequency) is a conventional single frequency sine wave continuous transmission technology. This is the traditional type of technology used in most basic metal detectors. Single frequency sine wave detectors create an electro-magnetic field, which is transmitted into the ground in a continuous wave. While the basic way that the signal is sent out and received back has not changed, the receive signal processing has improved enormously. This has proven to be a reliable and easy to use technology for finding gold.
3F (Three Frequency) provides three different transmit frequencies in the one metal detector, selectable at the flick of a switch. Each transmit frequency optimises the detector for different size targets and conditions. The three transmit frequencies are:
6.4 kHz - Best for large deep gold nuggets
20 kHz - Best for general gold detecting
60 kHz - Best for small gold nuggets
Having three selectable frequencies gives the versatility that is equivalent to three conventional single frequency detectors.
ACCU-TRAK continuously measures the level of ground mineralisation while the detector’s coil is swept in search of targets. Any changes in mineralisation, which can occur quite quickly, are analysed and the Ground Balance level automatically adjusted.
ACCU-TRAK ensures the detector is always correctly ground balanced and operating at maximum depth and sensitivity at all times with minimum effort.
FBS 2 combines Minelab's FBS multiple frequency rectangular-wave transmission (1.5 kHz –100 kHz) with advanced digital coil-to-detector communications. The precisely calibrated smart coils and detector electronics allow advanced signal analysis for more accurate detection.
Smartfind 2 greatly enhances Minelab's FeCo Discrimination to analyse and display a target's Ferrous (Fe) and Conductive (Co) properties on a full colour LCD.
Ultra-fast microcontrollers carry out digital signal processing to provide significantly improved target separation.
FBS (Full Band Spectrum) simultaneously transmits, receives and analyses a full band of multiple frequencies. This provides the detector’s electronics with even more information about a target and the surrounding environment than is possible with single frequency or BBS technology. This has a number of advantages, including:
High sensitivity across a wide range of target types and sizes, so you only have to cover the ground once.
Automatic sensitivity and ground compensation, so maximum depth is achieved even in mineralised ground, including salt water beaches.
Extremely accurate multi-channel signal conversion to precisely separate target signals from ground signals for maximum detection depth and high resolution target identification.
Smartfind two dimensional discrimination, giving you maximum target information, so that targets can be discriminated by both ferrous and conductive properties simultaneously
Find Every Target Type & Size with Every Sweep
Generally, high transmit frequencies are more sensitive to small targets and low transmit frequencies give more depth on large deep targets. FBS simultaneously transmits and analyses a full band of multiple frequencies from 1.5 kHz to 100 kHz and is therefore sensitive to both very small and large deep targets at the same time. This means you only need to cover the ground once and can be confident you’re not leaving ANY valuable treasure behind.
Automatic Sensitivity & Ground Compensation for Maximum Depth
As you sweep the coil in search of targets, Automatic Sensitivity and Ground Compensation monitor the full band of frequencies for changes in ground mineralisation. Whenever the level of ground mineralisation changes the sensitivity is automatically adjusted to maintain maximum depth. The ground compensation circuitry removes false signals caused by fast changing levels of ground mineralisation. Both of these advanced features work together to maintain maximum detection depth and sensitivity, allowing you to concentrate on listening for targets.
Extremely Accurate Multi-Channel Signal Conversion
FBS uses multiple channelled Sigma-Delta analogue-to-digital converter technology to digitise the analogue signals received by the search coil. This ultra-fast processing, using a digital reference (1 bit DAC), provides the microcontroller (MCU) with detailed information about the ground conditions and targets. This gives FBS the ability to precisely separate target signals from ground signals for maximum detection depth. It also provides Smartfind with the necessary high resolution target data to accurately plot targets.
Smartfind 2D Discrimination (not used in Safari detector)
Minelab’s exclusive 2D Discrimination technology analyses a target’s ferrous (Fe) and conductive (Co) properties simultaneously. This revolutionary approach is the most accurate technology available for determining whether a target is treasure or trash.
The information can be heard as different Fe-Co audio tones, as well as being displayed numerically and graphically on a 2D scale. Individual segments or larger areas of the display can be shaded to reject unwanted targets.
BBS (Broad Band Spectrum) simultaneously transmits, receives and analyses a broad band of multiple frequencies to deliver substantial detection depth, high sensitivity and accurate discrimination for a wide range of target types. This broad band of frequencies provides the detector’s electronics with more information about a target and the surrounding environment than is possible with single frequency technologies. The detector carries out advanced signal processing of these frequencies resulting in improved target identification accuracy and increased depth. This process also significantly reduces false signals from ground minerals, even in harsh and variable conditions, such as salt water beaches.
Find Different Target Types & Sizes with Every Sweep
Generally, high transmit frequencies are more sensitive to small targets and low transmit frequencies give more depth on large deep targets. BBS simultaneously transmits and analyses a broad band of multiple frequencies from 1.5 kHz to 25.5 kHz and is therefore sensitive to both small and large deep targets at the same time. This means you only need to cover the ground once, allowing you to find more treasure.
Accurate Multi-Channel Signal Conversion
BBS analyses multiple signal channels through a technique called multiplexing (MUX). These signals are compared to a digital reference (Vref. and DAC). The end result is high resolution accurate target signals that can be identified by the detector’s microcontroller (MCU). This analogue-to-digital conversion technique allows BBS to separate ground signals from target signals, achieving great depth and stability in difficult conditions.
In-Coil Signal Booster
RCB (Receive Coil Boost) circuitry greatly amplifies weak target signals, from small and deep targets, inside the search coil, where the signals are received. This has three main advantages over standard techniques of amplification inside the control box:
Greater immunity to electrical noise, reducing false signals
No loss of signal strength, and faint targets, through the cable
Improved detection depth and sensitivity
VFLEX uses state of the art digital electronics to enhance standard single frequency detection technology. This has the advantage of providing dependable performance and improved immunity to outside interference. VFLEX technology also has an added advantage that changing the detector’s coil also automatically changes the detector’s operating frequency. This means that an X-TERRA detector can operate at different frequencies allowing the detector to be easily modified to suit different detecting conditions.
VFLEX provides increased detecting performance with perfect sine wave transmission, an in-coil signal booster and coil selectable transmit frequencies.
World’s First All-Digital Metal Detectors
VFLEX transforms conventional single frequency metal detection technology by including two microcontrollers (miniature computers), one inside the control box and one inside the coil. Every time the detector starts up, the microcontrollers establish communication via a digital data link. The coil microcontroller communicates the coil’s configuration, size and exact frequency, so the control box can generate a perfectly matched transmit signal. This significantly reduces distortion and increases Target ID accuracy.
Perfect Sine Wave Transmission
VFLEX technology generates and transmits a perfect high quality sine wave, using the same technology that is found in high quality digital audio players, and is produced without distortion. The removal of distortion maximises power transmitted from the coil, therefore increasing detection depth and sensitivity. This also results in enhanced Target ID accuracy and greater immunity to both ground and environmental noise.
In-Coil Signal Booster
Weak target signals are amplified inside the coil, before the receive signal is sent up the coil cable where interference and signal loss can occur. This technique improves immunity to electrical noise by reducing false signals and increasing target signal strength, therefore improving detection depth and sensitivity.
Coil Selectable Transmit Frequencies (not used in GO-FIND Series detectors)
By changing the coil you can change the detector’s frequency, maximising sensitivity and depth for a wide range of target types and conditions. VFLEX gives you three frequencies to choose from: 3 kHz, 7.5 kHz and 18.75 kHz.
DIF technology eliminates interference with an operating metal detector, when it is switched off, by disengaging the coil's magnetic field.
DIF Technology is used in the advanced design of the PRO-FIND 25, it removes false signals and noise, commonly associated with other pinpointers.
Smartfind is Minelab’s unique two dimensional scale of discrimination. Smartfind graphically represents a target’s ferrous and conductive properties on the same display.
Smartfind is a feature of two Minelab metal detectors; E-TRAC and Explorer SE Pro.
The horizontal axis rates the target on its size/conductivity (CO), ranging 1–50 from left to right. The vertical axis rates the extent of the target’s ferrous characteristics (FE), ranging 1–35 from top to bottom. A FE value of 1 represents low ferrous characteristics and a value of 35 represents high ferrous characteristics. Similarly, a CO value of 1 represents low conductivity and 50 represents high conductivity.
Explorer SE Pro Smartfind:
The vertical axis rates the target on its size/conductivity (CO), ranging 0–31 from bottom to top. The horizontal axis rates the extent of the target’s ferrous characteristics (FE), ranging 0–31 from right to left. A FE value of 0 represents low ferrous characteristics and a value of 31 represents high ferrous characteristics. Similarly, a CO value of 0 represents low conductivity and 31 represents high conductivity.
W8 technology evenly distributes the detector’s weight, so that even after many hours of detecting you are unable to feel that any specific part of your body is carrying the detector’s weight. This means that you can detect for much longer without feeling any strain.
W8 technology employs three biomechanical strategies to transfer the detector mass (weight) away from the operator’s arm:
Remove flexion and extension muscle strain
Use solid skeletal structure to support loads
Avoid soft tissue anchor points
These effectively remove the need for the arm’s muscles to tense in a flexion extension position while swinging the detector, and therefore prevent the muscle fatigue and soreness that is commonly experienced with metal detecting. W8 technology also allows the arm to freely medially rotate and abduct to swing the detector without the need to hold it up off the ground.
You can never predict what level of soil mineralisation will be present in any given location, which is why Normal is the recommended Timing to start with. Then, you can let the detector tell you which Timing to use by sweeping the coil and listening to the stability of the threshold.
After performing an Auto Tune and Ground Balance you should commence searching, and if the detector is too noisy or signals on lots of hot rocks, then the Timing you are using is too aggressive for the ground you are on. You need to select to another Timing closer to the dark end of the below scale, e.g. Enhance.
If the detector is never noisy then the Timing you are using may be too conservative for the ground you are in, so you need to move closer to the light end of the scale e.g. Sensitive Extra or Sharp. Some Timings are more or less sensitive to certain targets, so try to select the Timing that is most suitable to the size of gold most commonly found in your area. As an example, in very mild ground, Sharp, Sensitive Extra and Normal will work equally as well, but Sensitive Extra will provide the best response to very small targets.
On bad EMI days here are a few tips that can keep your threshold purring:
A combination of the above should make a big difference in the stability of the detector, and will allow you to continue to find gold in difficult conditions.
The GPX 5000 is known to suffer from Electromagnetic Interference (EMI) particularly during stormy weather. There are three known reasons for this interference:
Put the Coil/Rx switch in Cancel. If you have slightly reduced depth than you’d expect, then your coil is a Double-D. If you have virtually no depth, then you have a Monoloop coil.
The Stabilizer function controls the point at which faint variations in the Threshold begin to be heard. These faint variations can either be ambient noise or faint target signals. As you increase the Stabilizer control, faint target signals will become louder, but the noise level will also increase, which may potentially hide a desirable target signal. The Stabilizer allows you to mask these faint variations to provide a perfectly stable threshold, improving your ability to identify faint target signals.
The Stabilizer is best left in the FP (factory preset) position until the soil conditions in the location are determined. Once the Rx Gain level has been set for the local conditions and other audio settings have been selected, the Stabilizer can then be used to fine tune the Threshold stability.
To find the optimal position of the Stabilizer, ensure that the coil is being swept across the ground. One number below the point at which the threshold begins to chatter, is generally the best setting.
The effect of the Stabilizer could be seen as having a similar effect to that of the Rx Gain control. However, the Stabilizer affects the audio processing only and does not change the Receive (Rx) signal, so should be used as a final stage fine tune. After making any adjustments to the Stabilizer, if the ground conditions change or you wish to change coils, you may need to reset the Rx Gain, but before doing so, return the Stabilizer to the Factory Preset setting first. This will ensure you select the most appropriate Rx Gain level to suit the conditions, and then you can fine tune using the Stabilizer.
Tip: By turning the Stabilizer control close to minimum (anti-clockwise) the threshold will be very stable, but you will have lost a lot of sensitivity to smaller targets. This can be a desirable feature in certain scenarios such as looking for large nuggets in a high-trash area, or using the GPX 5000and GPX 4800 to search for coins or treasure.
Tip: We would recommend the best order for setting these controls are:
Minelab's patented MPS detectors require precision aligning of the different operating channels in order to minimise interference caused by various sources of magnetic interference. Different timings can require a slightly different alignment for maximum effectiveness. The GP series introduced an option of three timings, and even though the performance of these timings were quite different, a single alignment still worked well, as the timings were quite similar electronically. With so many different timing options packed into the GPX-4500, it was no longer possible to rely on a single alignment, and so the Smart Electronic Timing Alignment or SETA concept was born.
SETA automatically sets a precise alignment for each Timing option, and these are saved to the built-in memory. What this means is that if you are regularly switching between timings, you should have no problems with noises caused by magnetic interference. This means that the threshold will remain more stable, and signals from highly magnetic rocks will be significantly reduced. This will allow you to harness all the power of the GPX 5000 and GPX 4800, and operate them more efficiently under different conditions.
A bonus of SETA technology is that the ground balance setting of each timing is also saved, so if you are switching between timings when investigating a suspected target signal, you won't have to continually re-ground balance the detector.
The Target Volume controls the strength of target signals, and at settings above 8 it will slightly increase the volume of the threshold as well. This is useful for very windy conditions, for people suffering from hearing loss, or when using external speakers. With the audio amplifier built into the Li-Ion battery pack, you can plug a speaker directly into the battery, and set an appropriate level of amplification using the Target Volume. Be aware that when switching from headphones to an external speaker, you may need to make minor adjustments to your Threshold and Volume Limit controls.
The Target Volume can be used as an Audio boost in quiet conditions, and can also be used to reduce or smooth out ground noise signals in highly mineralised soils. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability. A bit of experimenting may be required to find the optimum combination in different conditions.
NOTE: Whenever adjustments to the Gain are required, due to a change of coil or location, make sure the Target Volume is returned to the FP setting first. You can then fine tune to suit the new conditions.

To connect the WM 10 Wireless Module to your detector:
1. Press and hold the Power button on the WM 10 to turn it on
2. Press and hold the Pairing button. The Pairing LED will start blinking orange
3. On the detector, highlight and select Options > Wireless Enable
4. Highlight and select Wireless Connect
5. Use the right and left arrow buttons to select a channel and press Select. When Pairing is complete the LED will stop blinking and the WM 10 will emit a sound
If Pairing fails, try selecting another channel
The location of the WM 10 can be an issue for path loss. The human body is very attenuating, so having the WM 10 tucked on your backside away from the detector could cause issues. If you’re having issues place the WM 10 in a clear line of sight to the detector to get best results.

Combined audio produces different tones for highly ferrous objects, and objects with varying levels of conductivity. First you set the ferrous line (horizontal line) where you want ferrous targets to provide the audio response. For example, if you set it at 21, then any target with a ferrous reading of 21 or higher (larger number) will produce the audio tone that you program for ferrous targets. On the other hand, if the target has a ferrous reading that is less than 21, the audio response will be based on its conductive properties. In Combined audio you have four 'bins' representing conductive groups with conductive numbers running from 01 - 50. You simply move the lines to represent different target groups and assign a tone for each group. For example, you could set bin one with the lines at 01 and 14. Any target with a ferrous value less than 21, and a conductive value of 14 or less would fall into this bin and provide the audio tone you associated with it via programming.
Bin two, for example, could represent targets between 15 and 28. Bin three could represent targets from 29 - 40 and bin four could be the remainder of conductive targets with CO values of 41 - 50. With the numbers used in these examples, if you passed over a target with a FE value of 12 and a CO value of 44, it would provide the conductive tone you assigned to conductive bin four. If you passed over a target with an ID of 11 – 22, it would provide the tone assigned to conductive bin two. Again, the user can resize and assign tones to each target group (bin). For those of you who enjoyed hunting in Two Tone Ferrous with the E-TRAC, this takes it one step further allowing you to adjust the FE line, and break down the CO targets into four separate groups.
Gold can ID anywhere in the range of 10-09 to 13-30, and possibly outside of this range. Sometimes the Conductive reading can be very low, like 02, so to improve your chances you really have to dig everything including aluminium foil and pull-tabs.
Regarding settings, the standard Beach mode is quite suitable. One thing you can do is to change the Tone ID profile to Ferrous 35. What this does is it will make low conductive jewellery produce a higher tone than it would in Conductive profile, making it easier to recognize. You can also select Combine, and customize the tones to suit your personal preference.
For saltwater beaches, Manual Sensitivity is recommended, unless your beaches have high levels of magnetic mineralization. If your unit is running nice and stable on Sensitivity 18, try to push it a bit higher. In situations where you are actually detecting in the salt water, turn the Seawater setting on.
The other thing some beach combers often do is to open up the discrimination pattern a little. Mainly dropping the ferrous rejection slightly or simply search in Pattern 2 (simply press and release the Detect button). This is highly recommended on beaches with low levels of junk targets. In this case another thing you can try is changing the Audio Response to LONG. This can improve your ability to hear the very faint target response which jewellery can produce.

QuickMask is a simple way of adjusting your Ferrous & Conductive discrimination, or can be used as a secondary discrimination or all-metal pattern. The Ferrous (horizontal) adjustment is a trade-off between detecting good targets and rejecting unwanted ferrous junk. If the Ferrous slider is moved up the detector is less likely to detect iron, but deeper non-ferrous targets could be missed. Moving the slider down (towards higher FE numbers) could give more squeaks from iron, but makes it less likely to miss the 'keepers'.The Conductive (vertical line) slider acts as a traditional Discrimination knob where everything to the left of the knob position is rejected and everything to the right is accepted. If you don't want to be bothered by foil then determine the lowest conductivity that you would be interested in and reject everything to the left of that value.
The Ground setting helps stabilize target ID’s and the accuracy of the depth gauge.
In areas where the Auto Sensitivity operates quite high, the Neutral setting will perform best.
In grounds where the Auto Sensitivity is reduced the Difficult setting is best.
As always the answer to this question depends on your detecting style:
Normal mode is good for rapidly and automatically narrowing the audio response of a target.
Sizing mode is better when you want more control and don't want the detector to vary its baseline. The baseline is set by the operator when entering pinpoint. This is good for mapping a consistent outline of a target. It can also be useful if working in trashy ground when there are issues with adjacent targets.
There are two possibilities:
1. Passing over a target in Normal mode causes the baseline to be reset every time based on the strength of the signal received by the detector. If this baseline is set by passing the coil over a stronger signal then a weaker signal may not be heard. This can happen when sweeping across a target at different heights. Simply wait, while no targets are seen by the detector, the baseline will fall to a lower level.
2. Pinpoint is a non-motion mode. When in this non-motion mode the detector is unable to compensate for the slow drift of the channels of the detector. To re-calibrate, the pin point mode may need to be reset if operating in pin point mode for extended periods. Simply exit and return to pin point mode. This same effect may also cause the detector to emit a louder pinpoint tone than expected.
Yes, they do work differently, because the Discrimination and Pinpoint modes operate differently; one is motion, the other non-motion, The Depth Indication must suit each.
Depth in Discrimination
When in Discrimination mode, as opposed to Pinpoint mode, E-TRAC is a motion detector, that is, if it is held still over a target, no detection will be registered. Just as holding a motion detector motionless over a target will quickly kill the audio signal, holding it still will also make the detector see any target as infinitely far away. The detector must be kept moving over a target for any signal to be registered, both for detection and for the measurement of its depth.
Depth in Pinpoint
In Pinpoint mode, the detection signal does not die away when the coil is held over a target. The Depth Indicator also responds to this 'DC' signal when in Pinpoint mode. However, before the Depth Indicator responds, the centre of the coil must pass beyond the target; not very far, but just far enough to produce a slight diminution of the signal. Only when the Depth Indicator knows that it has seen the maximum signal will it make a judgement of how deep the target is.
Notes on Depth: Exact determination of depth is always a challenge in metal detectors. Larger or smaller targets (the larger tend to be indicated shallower), and more or less conductive targets will always produce some slight inaccuracy in the measurement. While that is so, E-TRAC has been calibrated so as to produce the same indications for the same targets, whether it is in motion mode or Pinpoint mode.
Extended conductivity range
The range of conductivity and ferrous IDs for the E-TRAC is wider than that of the Explorer SE Pro. For example it can separate between very low or very high conductivity targets, which are indistinguishable for the Explorer SE Pro. Also, where the ranges overlap, it has more resolution. A crude example: IDs 1-5 and 45-50 are new; the rest of the IDs (e.g. 6-45, i.e. 40 of them) are still more than those of the Explorer SE Pro (1-32 or so). Thus, the new range is wider and has more resolution. This, in turn, allows the user to better separate good targets from trash and to know what to expect before digging.
Straightened coins position
The ferrous coordinate of most coins in air is 12 +/-1, with slight deviations at the very high conductivity end. This makes it easier to remember the ID's of targets of interest or to note anomalies.
There is a lot of action behind the scenes (i.e. outside the Smartfind window) and this will benefit the user in the sense of less blanking from mineralised ground and hot rocks. The blanking will now indicate mostly rejected targets (e.g. ferrous junk) and less mineralised ground, so the user will be able to identify high trash and low trash areas. Also, this is very handy for searching in all metal (e.g. for ferrous relic hunt, or ferrous coin detection) where the user does not want to be overwhelmed by ground signals, yet wants to detect any type of metal.
Large conductive objects
Very large conductivity objects can be detected at very low FE numbers and if these are of interest (e.g. for certain types of treasure hunt) the pattern where there is no rejection at the upper side could be used.
Manual Sensitivity is for users to adjust how strong a signal needs to be before their detector makes a sound.
Automatic Sensitivity removes the burden of constantly trying to get the best sensitivity out of the E-TRAC, by adjusting the sensitivity according to the strength of the signals coming from the ground. The philosophy behind the automatically chosen levels is that one of the great attributes of E-TRAC is its ability to discriminate ferrous targets, even in difficult conditions. Automatic Sensitivity is constantly working to get the best sensitivity, with this in mind. It is not simply an 'Auto' knob for the Manual Sensitivity; it operates three separate levels of sensitivity at once, each applied to its own type of signal, and the level that is the highest is the one that will detect the weakest signal.
Suggested Sensitivity shows the best setting of Manual Sensitivity for the conditions. Remember that it is showing the level that it optimises the depth/discrimination trade-off in a way that might be different from your ideas on detecting. In that case, you might want to add or subtract one or more from the suggested setting.
Equivalent Sensitivity gives a guide to the sensitivity of E-TRAC as it is operating in Automatic Sensitivity. As ground conditions deteriorate, Equivalent Sensitivity falls; as they improve, Equivalent Sensitivity rises. Equivalent Sensitivity is almost always higher than the Suggested Sensitivity, because Automatic Sensitivity can adjust the three levels of sensitivity independently of one another; in Manual Sensitivity, the chosen level is tied to the average level.

If working in the water, on a mineralised beach, looking for fine gold jewellery, the 6” 18.75 kHz waterproof Double-D coil would be best. On a non-mineralised beach, the 9” Concentric 18.75 kHz is a good choice.
If working the dry sand only, one of the larger 10.5” round coils would cover more ground and go deeper.
Remember, the higher the frequency the more sensitive the coil is to smaller, low conductive targets such as fine jewellery. The lower the frequency, the better the response will be on larger high conductive targets, such as silver and copper coins, as well as large gold & silver rings.
In heavily mineralised ground, the abnormally high ground response can alter the way a detector normally reads a coin or other target, which will affect the ID stability on all Target ID detectors. What this means is that you may be walking over good targets that are being rejected and you wouldn't even know! The target ID stabilizer on the X-TERRA 705 uses a special filter specifically designed for high mineralisation, which makes a better decision on the type of target that is in the ground. The result of this is a more consistent ID on targets that you may have overlooked as junk, so you will dig up a lot more keepers at the end of the day. If the ground conditions are very bad, i.e. high iron content, heavy clays etc. then it is preferable to use the 10x5" Double-D coil in conjunction with the Target ID Stabilizer.
NOTE: Be aware that with the Target ID Stability ON, variable target ID's from some junk targets may also be stabilized, so in normal ground conditions it is preferable to operate with Target ID Stability switched OFF.
- Check batteries are fully charged
- Check orientation of batteries to ensure correct polarity
- Check to ensure there is no corrosion on battery door contacts
- Check volume setting in menu. Volume for the speaker and headphones are stored separately.
- Check if headphone icon is displayed on screen. If this icon is present with no headphones connected then the headphone socket requires replacement. Return to the nearest Authorised Service Centre.
- Check volume setting in menu. Volume for the speaker and headphones are stored separately.
- Ensure headphones are functioning correctly. If possible test with other equipment. Wiggle the cable to check for intermittent audio. This indicates a damaged cable which needs replacement. Return to your nearest Authorised Service Centre.
CU – Coil unplugged, many features are disabled if no coil is attached. If this error is displayed with a coil connected ensure plug and socket contacts are clean and there is no damage to pins.
CE – Coil Error, there is an error when communicating with the coil, ensure contacts are clean and undamaged. If possible check control box with another coil. If one coil continually gives a CE error return it to the nearest Authorised Service Centre.
CI – Coil Incompatible, the coil you are using is not compatible with the current model. Change to a coil which is compatible with your particular model.
OL – Overload, the detector has received a signal which is too strong to interpret. This usually indicates a large metal target is too close to the coil. Move the coil away from the source of the overload. This condition does not damage your detector; it simply indicates the signal cannot properly be identified.
The X-TERRA coils come in Low (3khz), Medium (7.5khz) and High (18.75khz) Frequency configurations.
- X-TERRA 305 is compatible with Medium and High Frequency coils.
- X-TERRA 505 and X-TERRA 705 models are compatible with all 3 Frequency coils.

1. Ensure you are using a High Frequency Double-D coil.
2. Ensure you are in Prospecting mode. This is indicated by a pick icon at the top of the screen. If a coin is displayed then the detector is in Coin & Treasure mode and will have a reduced sensitivity to small nuggets.
3. Run Noise Cancel and ground balance the unit, especially if you have switched the machine from Coin mode to Gold Prospecting mode.
Replace the batteries with new ones. A low battery can sometimes result in the unit failing to initialise properly.
If problem persists return unit to your nearest Authorised Service Centre.
For each model high sensitivity settings can be used on dry sand. On wet sand, or in transition areas where dry and wet sand combine, lower sensitivity settings on the X-TERRA 305 and X-TERRA 505 will reduce false sounds. Users in any case should not be afraid to reduce sensitivity. By being able to work more quietly you can often increase your "finds" through the increased quietness. We also advise against allowing the coil to touch the sand's surface - keep it flat and level and about an inch (2-3 cm) from the wet surface. Try "walking the beach" - adopting a line toward the surf line with sensitivity set to maximum. If the X-TERRA begins to "chirp" lower the sensitivity setting until the sounds disappear. Then turn and walk parallel to the surf line adjusting sensitivity so that the detector remains quiet.
Most X-TERRA Coils are waterproof - feel free to walk in the water if you wish but protect the control box! Continue to increase the sensitivity as long as the detector remains quiet.
After use at the beach, remove the batteries and clean their terminals. Clean and dry the rest of the detector with a soft cloth.
We always recommend selecting based on comfort and audio quality so check as many sets of headphones as possible before purchasing.
The following specifications will further assist in guiding your decision:
Frequency response: 18 - 20,000 Hz
Impedance: 100 ohm
Audio levels on the X-TERRA 305, X-TERRA 505 and X-TERRA 705 are set separately for headphone or speaker operation. Connecting or disconnecting headphones resets the audio level to the previously set level for that mode.
There are two issues to consider - frequency and coil type and size. Your choice of coil will depend on the type of ground you want to search and the types of targets you wish to find. Double-D coils are best suited to mineralised ground. A 10.5" Double-D coil is well suited to beach detecting. Double-D coils provide the best depth. Concentric coils suit soils that are cluttered with many individual targets - both wanted and unwanted. Pinpointing is sharper on concentric coils.
High frequency coils, such as the 18.75 kHz 10" x 5" elliptical coil, are recommended for gold hunting and for searching productive ancient sites where low conductivity items are more likely to be found. High frequency detecting can result in an increased tendency to signal more ferrous (unwanted) items. Smaller 6" coils are ideal for finding jewellery in manicured lawns, cluttered sites where wanted and unwanted targets might be located very close to each other, gold nugget hunting in rocky areas and working in shallow streams.
For more information, see the X-TERRA Coils comparison table below.
Generally speaking modern gold coins (such as those found in Europe that are less than 200 years old) are smaller and will likely produce a mid-range Target ID. Typically, smaller gold coins will usually have Target IDs in the range 13-19. Medium sized gold coins will usually have Target IDs in the range 20-29. Very large gold coins can have Target IDs of 30 or more. Some very small Celtic type gold coins have been found with a lower-than-normal conductivity and as such can have a Target ID less than 10.
When detecting allow experience to guide you since you may experience some variability due to your choice of X-TERRA model and coil. With experience you will find the sound of gold is fuller and more rounded. Take account also of the tonal response of all targets.
The value of experience lies in the ability to assess the signal tone and sound in addition to the numeric display when specifically searching for gold coins.
Use Prospecting Mode for nuggets. It is more sensitive to gold than other modes.
Ground Balance continuously.
Always use the Noise Cancel feature.
Use the highest Sensitivity setting that your ground conditions allow.
It may help to reduce the Preset Iron Mask to 0 (zero).
Always have a Threshold Tone on such that you can hear sounds which are faint but which are not confused by sounds from the ground itself.
Search slowly. Before proceeding allow the detector to reset after detecting unwanted targets.
Switch to Coin/Relic Mode to discriminate a target or, preferably, dig it anyway.
Always dig targets found in Prospecting Mode if they disappear in Coin/Relic Mode.
Use a Double-D high frequency coil (the elliptical 10" x 5" coil is recommended) for goldfields with highly mineralised soils.
Always Noise Cancel and Ground Balance before switching on Automatic Tracking.
Listen for faint, repeatable sounds. If they are faint but repeatable, dig them.

If no targets are detected or buttons pressed for 3 minutes, then the unit will start a slow beep.
This allows you to find the unit if it’s left behind on the ground after digging a hole. The beeping does not occur if it is in vibrate only mode .After 5 minutes of slow beeping the unit will turn itself off.
Unit probably didn’t finish the power on calibration and therefore will turn off 10 secs after the end of the power up beeps.
There was probably metal present when it was turned on. Commonly this is a ring on the finger of the hand holding it.
Tips for switching on:
Make sure there is no metal close to the probe
Listen for the third beep (short) before trying to detect with it
If it has been a long time since the unit was last used(several days) or there has been significant temperature change since it’s last use, then it may take about 5 seconds to calibrate
Calibration usually takes less than a second when the unit has been used recently
In highly mineralised soils:
Use the buttons to reduce the sensitivity to stop false triggering
Audio on and off:
Hold down the plus button while turning the unit on to enable audio tones
Hold down the minus button while turning the unit on to turn off audio tones
If your PRO-ALLOY meter is not functioning as well as it normally does, it probably needs a new battery.
To replace the battery:
1. First remove the black rubber protective case from the meter body.
2. Remove the two phillips head screws from the back of the case.
3. Replace the single AA battery and reassemble.
Note: because of the unique operating system of this meter, use only new, fully charged batteries!
If, after replacing the battery the meter is still behaving unusually, you may need to replace probe.
The test probe supplied with the PRO‑ALLOY is a consumable part that will need to be replaced.
A new probe is only necessary after several months if it's used frequently, or if the probe cap is left loose or off.
If the pen has reached the end of its useful life, the unit will most likely behave with similar symptoms of a low battery. While attempting to calibrate on 18K, you will not be able to adjust the needle up (or down) to the 18K mark. If you ever experiences this, try the following:
1. Make sure that the 18K sample is absolutely clean.
2. Change battery to a fresh one to see if the problem disappears. We recommend alkaline batteries as they hold a flatter and more consistent discharge curve.
3. If the two above points do not fix the problem, check the probe for a dry tip or other irregularities.
When your meter will not calibrate to 18K, it normally means the battery needs to be replaced. It can also mean the probe needs to be replaced. This will depend on usage and probe care. Always replace battery first, then replace the probe if the problem persists.
NOTE: It is important to make sure the probe cap is always snapped on tightly when not in use. If the cap is loose of off, the test tip will dry out and will not work properly.
