BASIC OPERATION

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.
