GPX 4500 Coil Overload

[Jin]

Lately, I've been experiencing the coil overload problem. Its hard to say whats causing it but it happens often. Probably not the best thing to do but I tend to slightly lean on the detector as I'm digging a target with the coil firmly against the ground. I've done this for a while with no problems before. It only shows the overload signal or shuts down when the coil is pressed against the ground. I've noticed it happens when using different coils as well. The only thing that has changed recently is the settings I use. I often have the rx gain flat out at 15 (gpx 4500) and other setting quite high also. Is it possible that the more extreme settings (when the coil is in contact with the ground) are the cause or is likely a problem with the machine?

In my humble opinion; NO!

The problem is likely in the wiring in the handle or the connections to the box itself….leaning on those could create a problem.
