Threshold Adjust:shrug:

[silversmith]

Hi...! I use an old Big Bud 220D that I love dearly. And it's fine on discriminate, however when using it in all-metals mode, looking for nuggets I sure wish I could set the threshold to a level that's hear-able Any one know if there's an adjustment pot inside these units to set this? Thanks for help. Ron.

Look for a small hole on the bottom of the box...If there is none, your gonna need the schematics for the machine to know which pot to tweak..if you see the small hole, you should be able to fit a jewelers screw driver in it to tweak the pot...Most of the time the only hole you will see is either for manual ground balance adjustment, or threshold adjustment...
