SENSITIVITY ADJUSTMENT

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 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 3000 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.
