Adjusting The Pole & Searchcoil - Laser Trident I Operator's Instruction Manual

16 TRIDENT I OPERATIOR INSTRUCTION MANUAL
Recognizing False Signals in Discriminate Mode
When operating in the DISCRIMINATE Mode, some "false signals"
may be caused by : 1) heavy concentrations of trash metal objects, 2) very
large trash metal objects 3) electrical interference. These signals are gen-
erally short, choppy sounds and sound different to "good signals" (good
target response sound).
At the end of your sweep, as you reverse the coil direction, the de-
tector is most susceptible to trash-induced noise. There are two ways to
tell whether these sounds are good deep signals or trash "noise." The first
is by repeatability. Trash-induced noises will not be regular as you sweep
the coil over the suspected target several times, whereas a good target re-
sponse will be repeatable. The second method is to switch to ALL METAL
Mode and check the target response sound. If the response is weak, it may
be a deep, good target. But if the response is very strong, it is probably
trash. Note that a coin close to the surface can give a double beep sound,
but it is regular and repeatable. Raising the coil an inch or two will restore
the single beep on surface targets.
When searching in the DISCRIMINATE Mode, it is best not to use
a higher DISCRIMINATE LEVEL setting than necessary. Nickels and
most small rings are rejected when the DISCRIMINATE LEVEL is set to
reject pulltabs on any metal detector that is a TR discriminator like the Tri-
dent I. If you don't dig any junk at all, you are surely passing up a lot of
good finds as well. Set the DISCRIMINATE LEVEL only high enough to
suit the conditions where you are searching. If there is any doubt whether
a target is good or not, dig it.
Recovering a Target
If the target is shallow and the soil is soft, you may be able to "probe"
and find the exact location of the target before you dig it. Since filling all
holes after you recover the target is so important, digging a small precise
hole is best. If the target is deep, you may need to dig a larger hole. As you
dig, occasionally check the hole with our detector to see if you have moved
the object, or have already dug it up. Be sure to fill all holes after you re-
cover the target.Two methods are shown on the next two pages that work
best. Be sure to protect your hobby by leaving the site cleaner than you
found it and with all holes filled !
ADJUSTING THE POLE & SEARCHCOIL
The pole length should be adjusted so that the detector does not be-
come uncomfortable or tiring after long periods of use. The detector grip
should rest in your hand with your arm relaxed, your elbow straight but
not locked, and with the pole extending out in front of you at the approxi-
mate angle.
You should be
able to swing the detec-
tor back and forth in
front of you – using re-
laxed shoulder move-
ment – while keeping
the searchcoil as close
to the ground as possi-
ble. This swinging
movement is often
called a "sweep".
The searchcoil
should not touch the
ground during your
sweep. The pole length
should be adjusted to
allow this without hav-
ing to lift the detector
with your elbow or
shoulder. The searchcoil
should rest about one
inch above the ground
while you are standing
erect. The angle of the
searchcoil should allow
the bottom to be parallel to the ground.
The pole length is adjusted by depressing the spring buttons and ex-
tending or shortening the pole until the spring buttons click into the set of
holes that gives you the most comfortable pole length.
To adjust the searchcoil angle, simply loosen the searchcoil thumb
nut slightly and move the searchcoil into the desired position. Tighten the
searchcoil thumb nut by hand so that the searchcoil will hold in place.
