Press 

• The detector always starts in the DISCRIMINATION Mode.

Motion is required.

• Default sensitivity is at about 70% of maximum, (08).
• All target categories except iron are illuminated, meaning that all metal

objects will be detected except iron.

MENU SELECTIONS

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 Metal Modes have independent sensitivity settings.
First highlight the mode, then adjust the sensitivity level for that mode.
