GMT or coil fault

[TheGoodKnightKiwi]

Curious to know if anyone has experienced a gain/overload issue in the past and what may be the underlying fault. Issue I has is with a 4x6 DD Shooter coil which overloads at anything over '3' on the gain (irrespective of location) and also seems non-responsive when the auto-balance is selected. I have tried the stock-standard Goldmaster DD coil and it max's out at anything over '7' but at least does auto-balance. I have emailed White's support but no response to date. would be interested in any suggested remedy or similar experiences.

I would say your GMT has a fault. The only other thing that's possible is the EMT (stray electrical fields) are really bad where you're located, and that's causing the overload. I'd also look at the socket where the coil plugs into the detector and be sure none of the pins are bent, or missing.

I've had an overload issue with my MXT and was a bad coil, it started out at a higher gain overload but got worse and would overload at a lower gain setting over a short time. HH
