The objective of the manual ground balancing is to achieve no change in the All-Metal mode's Audio Threshold (constant background humming) when performing the procedure called "pumping the coil" - slow raising the search coil up to 12 inches (30 cm) above the ground and then lowering the coil to 1 inch ( cm) off the ground surface. When the Audio Threshold is stabilized, the metal detector will be ignoring ground minerals under the search coil. The Ace is still a great detector for soil or dry sand, but not wet sand even with manual ground balance. So, manual ground balance may give you some extra depth, and may be worth doing. It's still not even close in performance to the AT Pro. Manual Ground Balance: Press Shift Button, then use (+) or (-) keys to change ground balance setting (pg. 22).
