AUTO GND BAL (AGB)
Setting range 1-200
Factory preset at 100
Description
The Auto Ground Balance (AGB) procedure is as follows:
Note: This procedure is required if the current GB setting is far different from
the current ground.
•
Hold the coil about 15" off the ground, press and hold the AGB
button while lowering the coil
•
The AGB Button MUST be released when the coil is about 3"
from the ground.
•
Take note of which direction (up or down) the Ground Balance
number changed.
o
If a minor manual precision adjustment is required, use
the MGB procedure aided by the above step.
•
For minor GB adjustments press and hold the AGB button and
bob the coil up and down to the ground.
•
When the tone has faded to a minimum, the detector will be
ground balanced.
Note: Do not hit the search coil with the ground surface as this can produce
unexpected results when trying to ground balance the detector.

Notes
Tip:
The AGB is less
effective at low
Threshold B settings
(less than the neutral
position), so when using
these settings use MGB
instead
