Garrett Metal Detectors Metal Detectors GTAx 550 - Manual (Page 30)

Relic hunters, prospectors and others may adapt
one of these to hunt for specific targets.
Any personal preference adjustments you have set
in the GTAx 550 with the various operating functions
will be retained when the detector is turned off.
Because ground and / or atmospheric conditions
can vary from place to place, it may be necessary
for you to adjust DEPTH (Sensitivity) occasionally.
Remember that you can instantly restore the
factory-set levels of all its controls. Simply press
and hold the POWER touchpad for approximately
ten seconds, or until the detector beeps.
Operating Mode Descriptions
The GTAx 550 is a slow-motion detector with precise
ground balance. The searchcoil can be hovered
over a target for only a few seconds because of
automatic circuitry. It should always be kept moving
slightly for proper target detection to occur, except
when the pinpoint touchpad is pressed. Detection
will then continue with the touchpad depressed,
even when the searchcoil is stationary.
