Sierra Super Trac Owner’s Guide
1. Trigger (on bottom of Hand Grip)
CENTER POSITION “Search” -
With the two position spring loaded Trigger on the hand grip in the center, the
ST
is in the
Search Posi-
tion.
In this position
ALL
metal targets will produce an Audio Response from a menu of seven different tones
which relate to the
VDI
numbers which appear on the Visual Display.
IRON
produces the
“Lowest Tone”
(Grunt)
thru
COINS
the
Highest Tones
. This feature makes the detectorist
immediately aware
of
the likely category of the metal item
without having to watch the Visual Display while search-
ing
. Each of the seven tones relates to the group of Display Categories as shown on the diagram at the bottom
of
page 4. Gold jewelry
will make a clearly
higher tone
than the
Iron Grun
t but
Lower than
the
high coin tones. After hearing the
Tone Alert, THEN
stop to look at the
Visual Display
for more informa-
tion before deciding whether or not to dig the target.
Personally, I usually dig ALL targets which
are NOT clearly Iron. In this way I don’t miss any good targets.
As you get more experience,
however, you will be able to sort out the different higher sounds along with watching the
VDI numbers
dis-
played on the screen and be able to ignore some of the
“non iron”
pieces of trash.
SQUEEZED POSITION “PINPOINTING & DEPTH READING”
After deciding you wish to dig the target,
Squeeze and Hold the spring loaded Trigger
on the hand
grip and crisscross the target as shown on the bottom of page 2. At this time the display will also indicate the ap-
proximate depth of a coin sized target in inches.
Once released the trigger will automatically return
to the Center “Search” position.
It will also be noted, that while the
Pinpoint Trigger
is
squeezed
, the
Sierra ST will STOP Track-
ing. It is very important to prevent tracking during pinpointing
as repeated passes while Xing
over the target may cause the tracking system to track
INTO
the target and diminish the signal smaller or deeper
targets.
