Notes

The Auto Ground Balance (AGB) procedure is now only used to
determine the direction (either up or down) for a User to perform a Manual
Ground Balance (MGB):
• Hold the coil about 15" off the ground, press and hold the AGB
button while lowering the coil in a very fast motion.
• The AGB Button MUST be released when the coil is about 3"
from the ground.
Note: Do not hit the search coil with the ground surface as this can produce
unexpected results when trying to ground balance the detector.
