SENSITIVITY ADJUSTMENT
ELECTROMAGNETIC
INTERFERENCE
The principle use for the Sensitivity
C o n t rol
is
to
eliminate
Electromagnetic Interference (EMI).
A hobby metal detector is an
e x t remely 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 pressing the
Sensitivity ▼ Pad 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 Titan 2000 XD 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.
