GENERAL INFORMATION 23
Thank you for purchasing the Laser Trident I. The Trident I was designed for the user who requires top line performance combined with total
ease of use.
The Trident I has the power and stability to handle the most hostile terrain. Its ability to punch through the ground should satisfy the most demanding operation. Sensitivity to tiny gold, silver, bronze coins and
artifacts should result in more of this class of find. Take the time to study
this manual & familiarize yourself with your detector and you can look
forward to many hours of fruitful searching in the years to come.
Good Hunting!
Sincerely,
Frank Mellish

Headphones
Most metal detectorists prefer to use headphones instead of the detector’s built-in speaker. Headphones help block out background noise (such
as wind) and make it easier to hear faint signals.Headphones with a built
in volume control will allow you to adjust the sound volume to your preference. Headphones also use less energy, and can increase your battery life.

Tesoro/Laser metal detectors and genuine Tesoro/Laser accessories
are sold only through independent Tesoro Authorized Dealers, who are
almost always metal detectorists themselves. They can answer your
questions about your Tesoro detector, what accessories may be helpful
and about metal detecting in general.
See your Tesoro Authorized Dealer for more information and prices
on optional accessories.
Searchcoils
The 9x8 monolithic searchcoil provided with the Trident I is designed for best all-around performance. Optional searchcoils may add to
your detector’s performance.
Smaller searchcoils give better “target separation”- that is, more
distinct target response for metal objects buried closely together-which
is very useful when hunting trashy sites. Very small searchcoils can deliver the best response and depth to small targets such as fine gold chains
with some sacrifice in depth on larger objects. Larger searchcoils give
a wider sweep, covering more ground, and provide greater depth especially on larger objects; however, they may not detect some very small
objects such as half-dimes and will have difficulty in very trashy areas.
Widescan searchcoils ignore ground mineralization better than
concentric searchcoils and may offer improved performance in extreme
ground conditions.
Selecting the right optional searchcoil depends on factors such
as what you are searching for and search site conditions. No one searchcoil is better than all the rest. Several optional interchangeable searchcoils are available for the Trident I. They are all easy to mount and
require no special tools.
OPTIONAL ACCESSORIES
GENERAL INFORMATION 21
Your Trident I was shipped with these parts:
1 - Upper Pole Assembly
Fully assembled, including upper pole system with handle grip,
padded arm bracket, and control housing.
1 - Middle Pole Assembly with Pole Lock
1 - Nylon Lower Pole Assembly
Fully assembled, complete with two friction washers, mounting
screw, and thumb nut.
1 - 9x8 Monolithic Searchcoil with 3’cable and scuff cover
1 - 9 Volt Alkaline Battery
1 - Operator Instruction Manual
If any of these items are missing, immediately contact the Laser
Dealer where you purchased your detector.
Assembling the Trident I is simple and requires no special tools. Just
install the battery, mount the searchcoil on the lower pole assembly, connect the pole assemblies together, wrap the excess cable around the pole,
and plug the cable into the control housing. Finally, adjust the pole length
and searchcoil angle and you’re ready!
Keep cables properly wound around the pole stems and protect them
during use. Floppy, pinched, or cables that become snagged during
use may short, causing erratic noises or unnecessary replacement of
the searchcoil.
Sweep the searchcoil carefully, especially when using it around rocks
and building foundations. Avoid hitting the searchcoil against hard,
solid objects and surfaces.
Keep your searchcoil slightly off of the ground during the sweep. especially when using in gravel or hard rocky dirt.
Always use a properly designed protective scuff cover on the search
coil.
Remove and clean out scuff covers periodically to avoid buildup of
mineralized dirt particles which will affect performance.
The searchcoil is waterproof and can be submerged in either fresh or
salt water. After the searchcoil is used in salt water, rinse it and the
lower stem assembly well with fresh water to prevent corrosion of the
metal parts.
The searchcoil is waterproof but the electronics are not, so always
prevent any moisture or water from entering the control housing and
never allow the cable connectors to become submerged in water.
If working in or near water, or if there is a possibility of rain, use a protective weather resistant pouch or plastic bag to cover the control
housing. Make sure it can “breathe” in order to ensure against condensation buildup inside.
After each use, clean the detector with a soft cloth to remove dust,
moisture, or other contaminants.
When transporting the detector in a car during hot weather, store it on
the floor of the passenger compartment if possible. Using a carry bag
gives additional protection. In any case, never allow the detector to
roll around unprotected in the boot or back of a pickup truck.
Protect your detector from dust, moisture, and extreme temperatures
during storage.
When shipping, use the original factory carton or similar heavy-duty
container and provide a minimum one inch of padding around all
parts.
Treat your detector as you would any sensitive electronic instrument.
Though ruggedly constructed and designed to withstand the demands
of normal treasure hunting, proper care is essential.
