Basic Care

The Trident I  IS A STURDY INSTRUMENT, BUT IT IS NOT DE-

SIGNED TO WITHSTAND ABUSE. In caring for you Trident I there are
several important “DO NOTs” to remember. DO NOT use it to pry rocks
loose or to beat bushes out of the way. DO NOT drop the machine into
water. DO NOT use it unprotected in the rain. DO NOT leave it exposed
at night where dew could form on it. DO NOT store it in places that could
get extremely hot (next to a woodstove, in an attic). DO NOT leave it in the
boot of a car or in the back of a hatchback-style car where high tempera-
tures could build up. DO NOT store it with the battery installed as batter-
ies may leak. DO NOT spray lubricants such as WD-40, or any type of
cleaners, solvents, sealants or other chemicals into or onto the electronic
parts, switches or controls. And finally, DO NOT attempt to modify or re-
pair the detector’s electronics as this will void you detector’s warranty.

THE WARRANTY DOES NOT COVER DAMAGE

RESULTING FROM AN ACCIDENT, NEGLECT OR ABUSE

.

Protecting your investment

Often detectorists are disappointed when their new detector slowly be-

comes less and less responsive and seems to have lost some of its original
peak performance. You can help avoid this from happening to you detec-
tor by following these basic care and protection guidelines:

Operate your detector exactly as recommended in this operator in-
struction manual. 
Use only high-quality alkaline batteries of the correct voltage. Never
substitute a different voltage. When using a Ni-Cad battery, always
use a separate convertible pack with the proper voltage output for the
detector’s design.
Remove the battery from the detector after each use. This will prevent
damage to the detector if the battery leaks.
The searchcoil cable is hard-wired to the searchcoil and protected by
a strain relief. It is very important that the strain relief remains intact
and should never be adjusted or tampered with.   

Your Trident I is equipped with an automatic battery test circuit so

that you can always be sure you are getting top performance. The battery
should be checked after the detector has been on for about 10 minutes and
then periodically when used for long durations.

To install or replace the battery, first make sure the SENSITIVITY

control is set to POWER OFF-turned completely counterclockwise past
the “click.” Remove the battery door from the back of the control housing.
Do this by pressing you thumb firmly on the louvered square – at the bot-
tom of the battery door- and sliding the battery door upward in the direc-
tion of the arrow.

Check the polarity on the battery and on the diagram inside the bat-

tery compartment. Make sure that they match and simply drop a fresh 9
volt alkaline battery into the compartment.

Note: If the battery is not in-

stalled properly, damage may occur to your detector.

Replace the battery door by sliding it into place making sure the

upper mount slots are in line and the lock tongue is snapped in place.
