Super Tune Your Trident I
The Trident I can be set up to get even better depth and sensitivity
while operating in the DISCRIMINATE Mode. Super tuning is accom-
plished by working in the DISCRIMINATE Mode and turning the
THRESHOLD knob to the highest setting.
Super tuning your Trident I will cause the threshold audio level to be
set too high for accurate All Metal or Pinpointing operation.
To start, turn the DISCRIMINATE LEVEL knob to just above the
IRON setting and turn the SENSITIVITY knob as high as it will go with-
out causing the detector to chatter. Check a target or two and notice how
far away you can get from the coil and still receive a repeatable audio sig-
nal. Now, turn up the THRESHOLD knob and recheck the targets. You
should see an increase in the distance from the target to the coil. Push the
PINPOINT button. Notice that the threshold tone is far too loud to accu-
rately identify some of your targets.
Take some time to try different targets and settings in an air test to see
how well your detector will work in the ground.
Adjust FREQ Switch
Your Trident I comes equipped with a frequency shift switch
(FREQ1, FREQ2, and FREQ3). This switch is used to change the operat-
ing frequency of your detector. This ability will help you work a larger
Adjust THRESHOLD
To adjust the threshold tone, push and hold the PINPOINT button
and then turn the THRESHOLD knob clockwise until you hear a slight but
steady tone. You will have to turn the knob to somewhere between the 10
o’clock and 3 o’clock position to get the best hum. Once you have set the
THRESHOLD, release the PINPOINT button. This will put you back into
the DISCRIMINATE Mode and you can continue with the Quickstart.
The purpose of the threshold tone is to give you a reference to judge
targets for pinpointing and to super tune the Trident I. (For more informa-
tion on super tuning, see the “Super Tune Your Trident I” section on Page
13.)
In the field, some targets may be small enough or deep enough that
they will not be able to generate an audio signal by themselves. By mon-
itoring a threshold tone, you already have an audio tone so changes are
easier to hear. However, if the threshold is set too soft or too loud, small
changes in the signal will be hard to hear. Take some time and find a thresh-
old level that is right for you.
Adjust SENSITIVITY
The discriminate circuit uses a silent search mode, meaning that no
sound will be heard until the coil goes over a target. The most common
way is to use the detector is to hunt in DISCRIMINATE MODE and push
the PINPOINT button to pinpoint a target. This will give you the advantage
