Owner’s Manual
like Disc mode, the All Metal mode requires that the coil be in
motion in order to respond to a target. If the coil is held steady
over a target it will get tuned out after a few seconds.
When the Pinpoint button is pressed and held it performs
the second function of enabling Pinpoint mode, which is typi-
cally used to assist in pinpointing a detected target. Pinpoint
mode is a true static mode in that audio response is maintained
as the coil is held steady over the target.
In both All Metal and Pinpoint mode a threshold audio is
applied and a target will cause the loudness to increase. The
CoinGT also supports VCO

audio whereby a target causes the
pitch of the threshold to increase. VCO audio is enabled by
pressing the
Tone ID
button while in Pinpoint mode.
Display
The CoinGT display provides information on the operation
of the detector as well as the detected target. On the right is the
segmented bar which shows the sensitivity level. On the left is
another segmented bar which shows the estimated target depth
in increments of 2”. A “TONE ID” icon indicates that multi-
tone audio is enabled. A low-battery icon will appear when bat-
tery voltage falls below about 9 volts.
A large 2-digit number gives the VDI response of the target
in both Disc and All Metal modes and the depth of the target in
Pinpoint mode. VDI responses are covered in the “More Info”
section. The numeric depth is given in 1/2” increments with no
decimal point. Therefore, a depth readout of “50” is 5 inches,
and a readout of “55” is 5.5 inches.
Across the top of the display are the segments for the 9 dis-
crimination zones. When a target is detected a pointer/cursor
points to the zone that corresponds to the type of target. Addi-
tionally, these zones can be disabled (rejected) by using the
Disc keypad buttons to move the cursor and select/deselect each
1. “VCO” means voltage-controlled oscillator
