1. SENSITIVITY

Use and to increase or decrease sensitivity while the SENSITIVITY

line is highlighted.

Maximum sensitivity setting is 12.

Minimum sensitivity setting is 4.

If the detector beeps erratically or beeps when there are no metal objects

being detected, reduce the sensitivity.

The searchcoil produces a magnetic field and then detects changes in that

magnetic field caused by the presence of metal objects. This magnetic field

that the detector creates is also susceptible to the electromagnetic energy

produced by other electronic devices. Power lines, microwave ovens, lighting

fixtures, TVs, computers, motors, etc…. all produce EMI which can interfere

with the detector and cause it to beep when no metal is present, and

sometimes to beep erratically.

HOW DEEP WILL IT GO?

The Delta Metal Detector will detect a coin-sized object, like a quarter, to a

distance of about 11” from the searchcoil at maximum sensitivity. Large metal

objects can be detected to a depth of several feet. Detectability is directly

related to the size of the metal object -- the larger the object, the deeper it can

be detected.

Accuracy of target identification is also related to distance from the coil.

Beyond a distance of 8”, the accuracy of target identification begins to

diminish.

Discrimination and All Metals modes have independent sensitivity settings.

First highlight the mode, then adjust the sensitivity level for that mode.
