Garrett Metal Detectors Metal Detector GTI 1500 - Manual (Page 55)

Last Mode
Use of this touch pad can be particularly
helpful while scanning because it effec-
tively converts your GTI 1500 into an
instantaneous dual, or triple-mode detec-
tor. Pressing and releasing this touch
pad returns detector operations to the
mode that has just previously been used.
Thus, it is easy to alternate between any
two operating modes, such as Coins and
Zero or Custom. Pressing the TREASURE
IMAGING touch pad, then, provides a
third, all-metal mode.
More On Target Audio
It is important to remember that the GTI's
audio causes weaker targets to be detect-
ed with shorter "beeps" and stronger tar-
gets to be detected with longer “beeps.”
When a metallic object is accepted, the
detector will, of course, “beep”. Some
rejected targets, however, may cause
audio to “break Up” or sound erratic. This
is generally a response to shallow, trash
targets and can be remedied by rais-
ing the height of your searchcoil slightly
when scanning (always keeping it level).
