Proper Scanning Techniques
Swing the searchcoil back and forth in front of you in
a straight line. Keep the searchcoil moving at a rate
of about one to two feet per second. Because of the
sensitivity of the GTAx 550 and its PROformance™
searchcoil, it is not necessary to operate with the
searchcoil touching the ground. The recommended
operating method is to hold the coil at a constant
height about one or two inches above the ground.
Detection of a metal target will be indicated by an
increase in sound and indications on your display.
Garrett's exclusive Belltone Coin Alert will indicate
you have discovered a target of high conductivity,
probably a coin.
Locate your target precisely by scanning back and
forth over the target to determine where the signal
is the loudest.
