Quick Start Instructions
(full)-
1.
Set the
Auto Trac
Toggle to the
Normal “preset triangle”
position.
2.
Be sure the
Trigger Switch
(under hand grip) is in the center (search) position.
3.
Turn the
Gain
control knob clockwise until the power clicks
ON
. Rotate the
Gain
Control clockwise to the
“preset triangle”
position between
9 & 10.
4.
Lower the search coil
to the ground, and
“pump” the coil up & down
3 or 4 times.
“Auto
Trac”
with automatically balance out the ground minerals.
5.
You may now search the ground by
swinging the search coil
in wide sweeps that overlap each other,
as near to the ground as possible without scraping ground. Your “ST” is a “Silent
Search” Detector. Thus it is operating without threshold hum. You should only hear an
audio signal when passing over a target. If you do hear spurious sounds, reduce the
Gain control a bit till they go away.
See a. below.
Hints
a.
The “ST” is NOT speed sensitive, so you may sweep your coil over the ground as
SLOW or FAST as you prefer. However, about one second per foot is suggested.
At this
point or at any time during your detecting, if you experience false signals
(constant beeping or popping)
,
you may need to
reduce
(counter clockwise) the
Gain
control knob. Excessive mineralization or external
interference from power lines, nearby detectors, etc. Can require a lowering of the
Gain
(Sensitivity)
a bit at a
time
, until your audio operates quietly and only responds to metal targets.
b.
Your “ST” is designed to hear
ALL
metal targets in the ground. While searching, you will be
alerted
to a
metal target by a
repeatable audio signal
when sweeping over target in both directions. The coil must be
kept in motion to hear the target. Pause slightly between sweeps to prevent tracking into the target.
c
.
The
Audio Alert
consists of a range of 7 distinct tones that correspond directly to the types of targets
indicated on the
Visual Display
. The lower the tone the lower the
VDI number
on the visual display. e.g.
The lowest tone is a Grunt for Iron or a Higher tone for a Coin. NOW!!!
Look at the
Visual
Display number
for further identification.
Negative numbers are Iron
and
Positive numbers are
possible good targets. If you decide to dig the
target,
SQUEEZE
the Trigger under the hand grip
to pinpoint the target
per page 5
. Make certain that you k
eep the trigger squeezed while pinpoint-
ing. 1. to prevent tracking into the target 2. to allow the ST to pinpoint without having
to keep the coil in motion while crisscrossing over the target as described on page 4.
