DEPTH SELECT (Sensitivity Adjustment)
Upon power-up, the detector defaults to 3/4 sensitivity. To increase to full
sensitivity, press the DEPTH SELECT touchpad once.
ELECTROMAGNETIC INTERFERENCE
The principle use for the Sensitivity Control is to eliminate
Electromagnetic Interference (EMI).
A hobby metal detector is an extremely sensitive device; the search coil
creates its own magnetic field and acts like an antenna. If your detector
beeps erratically when the search coil is motionless, the unit is probably
detecting another electromagnetic field.
Common sources of EMI are electric power lines, both suspended and
buried, motors, and household appliances like computers and
microwave ovens. Some indoor electronic devices, such as dimmer
switches used on household lighting, produce severe EMI and can cause
the detector to beep erratically. Other metal detectors also produce their
own electromagnetic fields; so if detecting with a friend, keep two metal
detectors at least 20 feet apart.
If the detector beeps erratically, REDUCE THE SENSITIVITY by using the
Depth Select Control.
SEVERE GROUND CONDITIONS
A secondary use for the Sensitivity Control is to reduce false detection
signals caused by severe ground conditions. While your Pilot contains
circuitry to eliminate the signals caused by most naturally occurring
ground minerals, 100% of all ground conditions cannot be anticipated.
Highly magnetic soils found in mountainous and gold-prospecting
locations can cause the detector to emit tones when metal objects are not
present. High saline content soils and sands can also cause the detector
to false.
If the detector emits false, non-repeatable, signals, REDUCE THE
SENSITIVITY.
MULTIPLE TARGETS
If you suspect the presence
of deeper targets beneath a
shallower target, reduce the
sensitivity to eliminate the
detection of the deeper
targets, in order to properly
locate and identify the
shallower target.

V. Press the TARGET REJECT
touchpad
a. An “X” will appear under
the IRON segment.
b. The “X” tell us that Iron
has been eliminated from
detection.
VI. Wave the Nail over the Search Coil
a. The Nail will not be detected.
b. The Nail has been "Discriminated Out."
VII. Wave the Quarter, Penny, and Nickel over the Search Coil
These non-ferrous objects will be detected with their own
distinctive tones.
VIII. Press the TARGET
REJECT
touchpad again
Another “X” will
illuminate under “AL ZN”.
IX. Wave all objects over the
Search Coil
The Zinc Penny will not be detected. make sure the penny is post-
1982; these are made of Zinc. CAUTION: some zinc pennies
within 1/2” of the coin surface will induce a high tone.
X. Press the TARGET REJECT touchpad again
a. A third “X” appears.
b. Pass all object over the search coil.
The nail, penny, and nickel are all eliminated from detection.
XI. Press the TARGET REJECT touchpad to return the detector to all-
metals detection, with no “X”s illuminated.
