Comprehensive Operating Manual & Guide to Metal Detecting
LCD VISUAL DISPLAY (continued)
The target indicator arrows are coded for signal strength — bold arrow for strong signals, caret
(
) arrow for medium signals, and small triangle for weak signals. When sweeping back and
^
forth to check a target, the indications corresponding to the strongest signals will usually be
the most accurate.
TARGET DEPTH
When the trigger is pulled to facilitate pinpointing an object, the numerical display indicates the
approximate depth of the object, in inches, based on the assumption that the object is a typical
US coin. Small objects will read deeper than they actually are, and large objects will usually
read shallower than they actually are.
G.C. PHASE
This is the ground cancellation setting, 0-99. It is displayed when in the Manual G.C. menu
setting, and when the trigger is pushed for FASTGRAB computer-assisted ground cancellation.
SETTING
This is illuminated when you are in the menu. When the word "SETTING" is indicated, the
number being displayed is a setting, and not, for instance, a Target ID indication.
MESSAGES
If a metal object or highly magnetic soil is so close to the searchcoil that the signal is
overloading the circuit, the message OVERLOAD - RAISE COIL will appear.
Such overloads will not harm the detector, but the detector will not detect metals properly
under these conditions. Raise the coil until the message disappears; the siren sound will also
stop. Resume normal detection.
The message RAISE COIL only appears when using the 3b or dP methods, accessed through
# OF TONES menu selection. This message indicates the presence of a target which may be
too close to the searchcoil to be accurately identified. For better target identification, sweep
the searchcoil farther away from the surface of the ground.
The message PUMP COIL TO GC will
appear when you push the trigger forward
to ground cancel. See the Manual Ground
Cancellation section of this manual for
instructions.
The message CAN'T GC can only appear
when the trigger is pushed forward,
invoking FASTGRAB automatic ground
cancellation. This message appears when
the detector is unable to measure the soil
in a manner suitable for ground canceling.
This message is usually the result of the
presence of metal. Try another spot to find
an area free of metal.
