GLOSSARY OF TERMS
Air Test - A sensitivity test performed by
outwardly moving various sized metal
samples under the metal detector search-
coil to measure the distance limit of detec-
tion. This test is not always an accurate
indicator of ground depth penetration ca-
pability. (See Bench Test)
Alkaline - A class of battery characterized
by the ability to sustain longer periods
of current drain and greater storage life
when compared to the standard carbon-
zinc type.
Bench Test - An air test to determine at
what discriminate settings various metal
samples are rejected or accepted. The test
is conducted in a non-metallic area.
Cache - Any intentionally buried or se-
creted hoard of valuables.
Conductivity - The measure of a metal
target's ability to allow eddy current gen-
eration on its surface.
Control Housing - A metal or plastic box
which holds circuit boards, indicators, me-
ter, controls and power supply.
Depth Penetration - The greatest mea-
sure of metal detector ability to transmit an
electromagnetic field into the soil matrix
and produce a target signal.
Discrimination - Adjustable circuitry
which ignores or nulls audio responses
from a specific conductivity range allow-
ing positive responses to be heard from
metals higher in conductivity above the
discriminate control setting. Designed
primarily to eliminate audio response from
trash metals.
Double Blip - A signal characteristic com-
mon to elongated ferrous targets such as
nails detected in the all-metal non-motion
mode.
Faint Signal - A sound characteristic of
targets that are sometimes deeply buried
or very small in size.
False Signal - An erroneous signal cre-
ated by automatic retuning overshoot,
ground voids or highly mineralized hot
rocks.
Ferrous - Descriptive of any iron or iron
bearing material.
Metal - Metallic substances; iron, foil,
nickel, aluminum, gold, brass, lead, cop-
per, silver, etc.
Metal Detectorist - A person operating
a metal detector in the field. This name is
preferred by many over Treasure Hunter.
Mineralized Ground - any soil that
contains conductive or non-conductive
components.
Motion Discriminator - A detector type
that requires searchcoil motion to activate
its simultaneous ground balance and dis-
criminate functions.
Non-Ferrous - Not of iron. Metals of the
precious class (i.e. gold, silver, copper,
etc.)
Pinpointing - Finding the exact target
location with respect to a searchcoil's des-
ignated center. Accomplished by interpret-
ing the centers of audio response width in
perpendicular direction or scans.
Searchcoil - A circular (can be other
shapes) plastic housing containing single
or multiple transmit and receive windings
in a specific orientation or configuration to
emit and receive signals from ground and
targets. (also called loop or coil).
Searchcoil Cable - An electrostatically
shielded cable of conductors (wires) which
convey signals to/from the searchcoil or
control housing.
Sensitivity - The measure or capacity of
a metal detector to perceive changes in
conductivity within the detection pattern.
Generally, the more sensitivity a detector
can smoothly provide, the more depth it
will achieve.
Signal - An audio response or visual in-
dication alerting the operator that a target
has been detected.
Slow Motion - A description of searchcoil
speed required to operate the motion dis-
criminate mode.
Sweep - the motion one employs in mov-
ing the coil.

ASSEMBLY —
The detector is shipped fully assembled in one carton. Only two
adjustments are necessary, and no tools are required.
1. Turn the search coil to the scanning position. It may be nec-
essary to loosen the knobs securing the coil and then tighten them
again. Make sure that the knobs are tightened (by hand) securely
after the search coil is positioned.
MIND YOUR MANNERS
Filling holes and obeying NO TRESPASSING Signs are but 2 require-
ments of a dedicated metal detector hobbyist. A sincere request that
Kellyco makes to every user of a detector is that each place searched be
left in a better condition that it was found. Thousands of individuals and
organizations have adopted this formal.
Metal Detector Operators Code of Ethics:
• I will respect private and public property, all historical and archaeological
sites and will do no metal detecting on these lands without proper permis-
sion.
• I will keep informed on and obey all laws, regulations and rules governing
federal, state and local public lands.
• I will aid law enforcement officials whenever possible.
• I will cause no willful damage to property of any kind, including fences,
signs and buildings and will always fill holes I dig.
• I will not destroy property, buildings or the remains of ghost towns or other
deserted structures.
• I will not leave litter or uncovered items lying around. I will carry all trash
and dug targets with me when I leave each search area.
• I will observe the golden rule, using good outdoor manners and conduct-
ing myself at all times in a manner which will add to the stature and public
image of all people engages in the field of metal detection.
Warning!
Any metal detector may detect underground power lines, explosives or
other items which when struck could cause personal injury. When search-
ing for treasure with your detector, observe these precautions:
Do not hunt in an area where you believe there may be shallowly buried
underground electric lines or pipes.
Do not hunt in a military zone where bombs or other explosives may be
buried.
Avoid striking any line known to be or suspected to be carrying electrical
power.
Do not disturb any pipeline, particularly if it could be carrying flammable
gas or liquid.
Use reasonable caution in digging toward any target, particularly in areas
where you are uncertain of underground conditions.

IN THE FIELD TIP FOR USING YOUR Viper TRIDENT
2. The Viper TRIDENT is an Ultra Slow Motion Metal Detector.
When using this detector the coil must be in motion to detect any
target. A sweep speed of about 2 feet per second is perfect. You
can hunt as fast as you want or as your pace dictates.
3. Correct arm position. Adjust
the lower stem so that your arm
is hanging in a comfortable posi-
tion by your side with the coil
about 1 inch off the ground.
1. Always keep the bottom of the coil level with the ground. Try
to maintain coil 1 inch off the ground at all times. You do not need
to scrub the ground with the coil.

Locate the round battery door
cover and using a coin unscrew the
cap in a (ccw) direction. (See inset)
Remove cap to expose the 9 volt
battery. Now you can carefully pull
the battery out, unsnap it from its
contacts and replace. Only use high
quality 9 volt batteries designed for
electronic devices.

Battery Test Feature –
The Viper TRIDENT has a built-in automatic battery testing
circuit. When the batteries get below 7.2 volts you will hear, through
the headphones, a continuous 400 Hz tone. When the tone is heard it
is time to replace the battery with a new one.

The Viper TRIDENT is a slow motion type detector, in other words
the coil must be in slow motion to respond to any target. By sim-
ply moving the coil back and forth over the ground this motion will
activate the automatic ground balance and tuning circuits of you
detector and keep it at its optimum tuning levels. When scanning
the ground try to keep the search coil about 1 inch off the ground.
DO NOT scrub the ground, you may get some "False Signals" by
doing that. Please refer to the following drawings for the correct way
to sweep and hold your metal detector.

OPERATION OF THE DISCRIMINATION CONTROL –
The DISCRIMINATE Control works in the 3 different Zones.
The Viper TRIDENT has been designed to be easy to use by dividing
it into 3 discrimination (at a glance) zones. Each Zone has a mini-
mum and maximum range and the discriminate information below
will give you a guideline as what targets are accepted or rejected in
each given Zone. Each Zone can be fine-tuned by the operator to
accept or reject most trash targets. If you want to hunt in All-Metal
you simply rotate the discrimination control fully counter clockwise
position.

SENSITIVITY CONTROL –
As you know, this control has 2 functions, to turn the Viper
TRIDENT metal detector on and off and also enables you to set the
amount of operating sensitivity (SENS). It is recommended that
you start out in the Factory recommended starting point or pre-set
position marked on the detector itself. By starting out at the pre-
set point the Viper TRIDENT is set at the normal detection depth
range. The normal range is good for most soil conditions, but by
increasing this control clockwise to the maximum position you will
get better depth on older coins. This control is extremely helpful
in elimination false signals caused by high minerals. If you are
experiencing false signals you should decrease this control until
these signals are minimized.
NOTE: Some "False Signals" are normal, particularly on Salt
Water Beaches.

NOTE: Most Eliminated Trash Targets will give a broken or chattered sound when discriminated, this
is normal and is a design feature of this underwater detector. It was designed this way so you can eas-
ily identify trash targets. Some trash targets will give NO sounds at all. Practice using the Elimination
control by putting some different coins and trash items on the ground in a straight line about 10 inches
apart. Pass each item once and then come back and increase the elimination control knob little by little
and listen to the changes in the audio response on the trash targets as you keep increasing this control.
Remember even good targets can be eliminated at the maximum discrimination settings.
TIP: Always keep
the Trash Elimina-
tion Control at its
lowest possible
settings so you
will not reject
nickels and
small gold rings.
