Find an area on the ground outside where there are no metal objects.
Bury few samples at a separation distance of 1-2 feet apart as targets for the testing.
While holding the search coil level to the ground about 1-2 inches above the surface,
slowly move the s earch coil over the area where you placed the samples, sweeping the
search coil in a side-to-side motion.
When a sample is being detected, a tone will be generated.
Slowly lifting up the search coil, the depth indicator on the LCD display increases. This
means that the target is a real one. Return to the original position to read the depth level
of the target.
Note: The indicator reading is for reference only. The exact depth of a target depends on
the projection area on the search coil
4.5 OPERATION TIPS
4.5.1 Objects not on the list
If the highlight indicator jumping from one target icon to another or vice versa while an
object is being detected, the detected object may be an object not in the display list or the
soil is highly mineralized. The latter one can be ruled out by decreasing the sensitivity
level and search again.
4.5.2 False Signal
The detector is extremely sensitive and will find very deeply-duried object. Because of this,
trash-induced signals and other sources of interference might cause signals that seem
confusing. The key to handling these types of signals is to dig for only those targets that
emit a strong, repeatable signal. As you sweep the ground, learn to recognize the
difference between signals that occur at random and signals that are stable and
repeatable.
To reduce false signals when searching in very trashy ground, scan only a small area at a
time using slow, short overlapping sweeps.
4.5.3 Searching Coil Sweeping
Keep the search coil moving at a comfortable rate. TAKE YOUR TIME. If you walk too
fast you can t overlap yours sweeps and you ll miss a lot of ground. Also if you sweep too
fast, you ll lose sensitivity and miss the target.
Keep the search coil parallel to and as close to the ground as practical. This is important
for maximum coverage and depth. If you re hunting on a lawn you can rub the coil right on
the grass.
