Golden mask 4WD GB too low

[Rivers rat]

Hello to all i got an issue to GB my GM4 WD i bought it with 3 large coils but got no use to them as my plan was to use a 5" coil

Problem is while testing it in a river on Sunday i couldt GB and all hot rocks sounded like targets.I asked the dealer and he mentioned the machine will need to be adjusted from inside.

Do any of you know where and if a fine tuning GB is located on the PCB.


Thanks for your help

Are you unable to use the detector in either "Manual" as well as "Auto" ground balance?

There is no auto in this version it must work with the other coils.

According to page 5 and 6 of the manual you are able to use Auto GB with the 4WD (although there is no switch, you adjust the potentiometer to the left red portion of the scale)

RR, got a schematic for a Gold Mask, purportedly a 4WD, tried to upload it, but it is too smart for me. If you still got my email, let me know if you want it and I will email it to you. Wll, do not need to send it, it finally uploaded by itself. Like I said, it is too damn smart for me... How is digging for the relics in the Thames River? Still making desserts?
