Well the pots inside are generally for tuning the detector. Unless the factory purposely mistuned them
or you make other changes they probably won't make the detector work any better. I did retune my
Bounty hunter and gained 1 - 1.5" in depth but it threw the discrimination off.

Most things that are computer controlled have secret buttons that you push while powering up to
get into the manufactures calibration menus. You can try pressing some while powering up to see
what happens.

Where did you find some info that there were these in the Garrett MD's?
