Just a reminder and brief explanation of Ground Balance on the CTX from this months Minelab FBS Newsletter:
USE OF THE GROUND BALANCE OPTION ON THE CTX 3030
The last few Bootcamps I have been asking who uses the Ground Balance function and was surprised to get some hands to go up. The thing you need to remember is that this option was added for one thing and that was for hunting in SEVERELY mineralized ground where the Noise Cancel function would not help. Pressing the lower touchpad brings up the GB menu and pressing the center touchpad activates it. The downside is that you balance to the ground under the coil and if conditions change 10 feet away, performance suffers unless you redo it – it is not a tracking ground balance as found on some detectors but fixes the value to where it was when you did the GB adjustment. If you are not hunting in the Southwest or Australia, leave this function OFF and you will not have any issues. In the last two sessions, there were 5 people that had it active and when removed, they were shocked at how much more stable their detector was. Check it before you head out and make sure it is unchecked.
