The Gold Standard

This machine is a metal detecting beast. In the four years I have owned my CTC have found literally hundreds of coins. That's no exaggeration, in decimal currency alone I have recovered the purchase price of the CTX. Even with pre decimals I have found over 300 coins. Then there's ALL the other relics I've recovered on the beach and in the dirt. Unfortunately two months ago my CTX was stolen from my house. Despite a multitude of cheaper and more up to date machines being available I will be purchasing another CTX when my insurance comes through. By the way I also own an Equinox but the CTX is way better. Its not just the incredible detection power, its the stability of the machine, its phenomenal discrimination capability and the incredible endurance of the Battery, you will never run out of battery on a single days use. And for multiple days detecting you can buy a second battery if you are out in the bush with no recharging facilities. One thing I hear often about this machine is that its too heavy, sure it is heavier than other machines, but having the battery behind your elbow makes the machine so very well balanced that you can swing it all day without fatigue. And who in their right mind doesn't want to detect all day. Am i right?????
