3) Notice the Target Indication

Note: You can only ZAP objects that register under the seven left-most segments (from Iron to Zinc).

4)Press ZAP. An "R" appears under the segment to be eliminated.

5)Pass the search coil over the same object again. The undesirable object is eliminated from detection

The ZAP control is easy to use in the field. As you are detecting, and encounter an object which you wish to eliminate from detection, simply press the ZAP touch pad after detecting the object.

The ZAP control eliminates the most-recently detected object category from detection. The category eliminated is indicated with an "R".

PIN POINT MODE

Since long-buried objects can appear exactly like the surrounding soil, the process of finding the exact location of a small object, such as a coin, can be time-consuming and frustrating. Objects buried many inches deep present an especially daunting challenge. In addition, during the unearthing process, care must be taken not to damage valuable relics. The best solution to these problems is the no-motion PINPOINT mode.

At any time during operation, press the PINPOINT touch pad, and the detector enters the no-motion mode. In the PINPOINT mode, any object in the coil’s detection field will induce a monotone hum. The location of a coin-sized object can be discerned with pinpoint accuracy as it will induce a tone only when it falls within the inner circle of the search coil. Pass the coil slowly over and around the target zone, and you will quickly see the target’s exact location.

Be sure that the detector is properly GROUND BALANCED before using the PINPOINT MODE. See page 20 for manual ground balancing instructions. Also, consult page 22 for proper no-motion field techniques.

The Target Identification and Target Depth indicators are disabled in this mode. To discern the identification and depth of an object, you must use one of the motion modes of operation.

HEADPHONE JACK

Using headphones (not supplied) with your metal detector makes it easier to identify subtle changes in the threshold levels for better detection results, and also reduces drain on the batteries. The Discovery 3300 Metal Detector has a stereo headphone jack located at the rear of the case.
