ASSEMBLING YOUR DETECTOR
Your detector is standardly equipped with 9X9" and 12X12" new SEF PRO
coils. These coils have better sensitivity and depth, better pin-pointing, keep
perfect balance even in high temperature range.
For getting acquainted with the detector’s operation we recommend you at
first use the smaller sized 9X9" coil. The 12X12" coil is more sensitive and
deep, but to use it you should have some more experience with the
operation of the detector.
For first tests and acquaintance with the detector we recommend you make
this in field conditions, away from the electromagnetic interferences of the
built up areas.
The length of the handling should be adjusted so that
the detector does not become tiring or uncomfortable
after long use. The detector grip should rest in your
hand with your arm relaxed, with the shaft extending
out in front of you. You should be able to swing the
detector back and forth in front of you, using relaxed
shoulder movement. The search coil should not touch
the ground during your sweep. The angle of the search
coil should allow its bottom to be parallel to the ground,
as shown on Figure 1 .
Swing the detector from side to side in about three foot
arc, overlapping succeeding strokes well. The detector
is designed to get maximum depth without the requirement
for speed of sweeps, so go at a pace that is comfortable for
you. In fact, trying to hunt too fast may even cause a loss of depth in heavily
mineralized locations. Regardless of which mode you are using, try to keep
your search coil height constant and at about an
inch over the ground surface. Most people tend to
raise the coil at the end of the sweeps, much like a
pendulum, especially if they are in a hurry (Figure 2)
Try to avoid this as any increase in height from the
ground will cause a corresponding loss of detection
depth. This is easy in lawns, where you just allow
the coil to rest on the grass as you sweep from side
to side. In rough and rocky areas it is not so easy.
Hitting the ground or rocks may cause false signals.
The sharp lowering, pressing the coil to the ground,
especially in wet and heavily mineralized grounds,
could also cause false signals.
