Q
UICK-START DEMONSTRATION
I. Supplies Needed
• A Nail • A Quarter
• A Pull-Tab from a beverage can • A Zinc Penny (dated after 1982)
II. Position the Detector
a. Place the detector on a
table, with the search coil
hanging over the edge.
(or better, have a friend
hold the detector, with
the coil off the ground)
b. Keep the search coil 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 search coil back toward the
detector body.
III. Power Up
Press the ON touchpad.
The detector will beep twice and
the full sensitivity setting will be
indicated on the left of the display.
IV. Wave each Object over the Search Coil
a. Notice a different tone for each object.
Low Tone: Nail
Medium Tone: Pull-tab & Zinc Penny
High Tone: Quarter
b. Motion is required. Objects must be in motion over the search coil
to be detected.
V. Press the MODE touchpad(*)
The detector will beep twice and
the sensitivity setting will flash
on the left side of the display.

Upon power-up, the detector defaults to 3/4 sensitivity. To increse to full
sensitivity, press the Sensitivity
▲ touch pad.
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 magnetic 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 will 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 pressing
the Down-Sensitivity Arrow
▼ 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 Outback
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.
