Sensitivity Adjustment
To change the detector's sensitivity,
press SENSITIVITY
or
. A
double beep indicates the setting is at
the maximum or minimum. At
maximum sensitivity, a quarter can be
detected at a distance of approximately
8" to 9" from the searchcoil.
ELECTROMAGNETIC
INTERFERENCE (EMI)
The principle use for the Sensitivity
Control is to eliminate Electromagnetic
Interference (EMI).
A hobby metal detector is an extremely sensitive device; the searchcoil creates its own magnetic field
and acts like an antenna. If your detector beeps erratically when the searchcoil 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 6m (20 feet) apart.
If the detector beeps erratically, REDUCE THE SENSITIVITY by pressing Sensitivity
on the left of the control panel.
SEVERE GROUND CONDITIONS
A secondary use for the Sensitivity Control is to reduce false detection signals caused by severe ground
conditions. While your Adventure 5500 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 sometimes 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.

Quick-Start Demonstration
I. Supplies Needed
• A Nail
• A Quarter
• A Zinc Penny (dated after 1982)
II. Position the Detector
a. Place the detector on a table, with
the searchcoil hanging over the edge.
(or better, have a friend hold the
detector, with the coil off the ground)
b. Keep the searchcoil away from walls,
floors, and metal objects.
c. Remove watches, rings and other
jewelry or metal objects from hands
and wrists.
d. Turn off appliances or lights that
cause electromagnetic interference.
e. Pivot the searchcoil back toward
the detector body.
III. Power Up
Press
IV. Wave each object over
the Searchcoil
a. Notice a different tone for each object.
Low Tone: Nail
Medium Tone: Penny
High Tone: Quarter
b. Motion is required. Objects must be in
motion over the searchcoil to be detected.
V. Press
DISCRIMINATION
The detector will beep and an "X"
will appear over the iron segment.
