BASICOPERATION

POWERING UP

Press the POWER touch pad.

• The detector will beep 4 times

• All display segments will illuminate momentarily

• The SENSITIVITY

and BATTERY indicators will stay illuminated

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
