OPERATING INSTRUCTIONS
The GTI 2500 automatically operates in the All-Metal
mode when attached to the TreasureHound. Auto-
Threshold, which maintains the audio threshold at its
previously selected level, is disabled. The threshold
sound may fluctuate due to changes in temperature or
ground conditions. If this occurs, you can retune the
audio threshold by simply pressing and releasing the
All-Metal button.
