MOTION and NO-MOTION MODES
Depending on the operation mode selected, the Discovery 3300
detects metal both with the coil in motion, or with the coil motionless.
In the PINPOINT mode of operation, metal is detected with the coil
motionless over the ground. This no-motion operation helps to locate
the exact location of buried objects, and is very useful in
understanding the size and shape of buried metal objects. The
PINPOINT mode offers deeper ground penetration, but cannot
classify targets, nor indicate their depth.
The other operating modes require the coil to be in motion to detect
a target. When in the DISCRIMINATION, ALL-METAL or NOTCH
modes, the coil must be in continuous motion. It is often useful to
search for targets in a motion mode, and when identified, pinpoint
their location with the PINPOINT control.
SENSITIVITY
At its default sensitivity setting, the detector will detect a coin-sized
object, such as a quarter, buried approximately seven inches deep.
To change the sensitivity level, and thus the detection depth, press the
SENSITIVITY

or

keys. The 6-segment scale at the left of the
display, above “coin depth”, indicates the sensitivity level when these
touch pads are depressed.
CAUTION:
At higher sensitivity levels, the detector is susceptible to electromagnetic
interference from electronic devices. Reduce sensitivity if demonstrating
indoors or if using near power lines or electrical equipment.
Reduce sensitivity if detector emits false signals
