HERE IS MY COMMENT FROM BRAD AT GARRETT:
Hi Anthony,
Those two pots are for internal adjustments, and are not made for tweaking. They are set against our procedures here at the factory, also the pots don’t adjust the ground balance.
As for you setting up your detector for beach hunting, I would hunt in beach mode. It will pick up all the gold, silver and coins. But it will eliminate the bottle caps, foil and iron targets. Now it will still pick up pull tabs as pull tabs read right in the middle of the gold area.
Please let me know if you have any other questions or concerns.
Thanks and have a great day,
Brad Keel

If its like the ACE 250 one of them controls the timing that the "receiver" portion of the detector is "listening" to reflected signals from the target. Setting it too low will reduce sensitivity a lot. Setting it too high will make it false all the time. The sweet spot is where its set at the factory and the balance of the circuitry determines how much of the pulse to "read" which in turn allows you to "adjust" the sensitivity.
In short, its not ground balance. Its used to compensate for slight variance of the passive and active components in the design and should be left alone.
