METAL touchpad while scanning the searchcoil for only a few seconds in a normal manner.
Release the touchpad and Auto Track will continue to track ground minerals and instantly
make all necessary adjustments.
SETTING DISCRIMINATION: The GTI 2500 features fully adjustable notch discrimination. It
offers multiple selectivity and the ability to reject and accept targets in both the ferrous (iron)
and non-ferrous ranges.
SEARCHING: Begin your search for coins or other treasure by lowering the searchcoil to a
height of from one to two inches above the ground. Scan in front of you at a speed of one to
two feet per second by moving the searchcoil from side to side in a straight line (not an arc).
Always try to maintain a constant height. At the end of each scan path, move the searchcoil
forward approximately one-half to two-thirds its diameter and scan a path in the opposite
direction. This overlapping insures that you do not miss targets.
When any acceptable target is found, the sound level from the detector’s speaker or
headphones will increase to alert you. The voice feature, if activated, will supply verbal target
information at this time also. The Imaging Grid will display target size and depth information at
this time as well.
TARGET IDENTIFICATION: Target ID, conductivity classification, and size and depth of the
last target over which the search coil passed will be indicated on the LCD Display Panel.
Encrustation or patina, however, may result in improper classification. It is recommended that
you always dig any weak, but audible target signal. It might be a coin just at the edge of your
search coil’s detection range.
TREASURE IMAGING (Electronic Pinpointing): Electronic pinpointing offers greater accuracy
in target location. When a target is located, press and hold the TREASURE IMAGE touch pad
to activate the detector’s electronic pinpointing mode. A wealth of information is now beneath
your fingertip, The Imaging Grid is displaying target size and depth data and the Graphic
Target Analyzer (GTA), the Upper and Lower Scales, providing information to assist in the
targets recovery. As long as the touch pad is pressed, the detector will operate in this mode.
Still pressing the touchpad, place the searchcoil near but not above the target. Then, move the
searchcoil over the target area. When sound is loudest and the upper scale reading is at its
greatest deflection to the right, the target will be beneath the center of the searchcoil. At the
same time, the lower scale reading is at its greatest deflection to the right, measuring depth.
These two scales, upper and lower, cannot overlap each other. Depth reading is automatically
calibrated regardless the size searchcoil coil used. After the touchpad is released, the detector
will automatically return to the mode previously being used.
Practice pinpointing by placing a coin on the ground. Scan over this coin and use both
pinpointing techniques just described. Notice how accurately you pinpoint. You should quickly
become proficient to within one-quarter of an inch.
SEARCHCOILS: The GTI 2500 may be used with three (3) Scorcher and two Imaging (2)
searchcoils and Garrett’s Treasure Hound depth multiplier attachment with Eagle Eye
Pinpointing.
