Garrett Metal Detectors Metal Detectors GTAx 550 - Manual (Page 29)


MAKING ADJUSTMENTS
When you first press the POWER touchpad, your
GTAx 550 is ready to hunt, in the B (Coins) operating
mode with threshold, depth and discrimination preset
at the factory. Any or all of these operating levels
can be easily changed.
Whenever your detector is on it will return to the
detection mode in which it was previously being
used. Mode selection will be illuminated on the
graphic display. You can change to the other mode
simply by pressing the Last Mode touchpad.
In addition to the familiar Zero and Coins
discrimination detection modes preset at the factory
as Modes A and B, the GTAx 550 permits a user
to design personal modes through use of the (+)
and (-) touchpads. It is important to remember that
these special modes of detection can be chosen at
the discretion of the individual operator. Many GTAx
550 owners will never use individual modes and will
hunt only in the preset B (Coins) or A (Zero) modes.
