SETTING UP
FOR LAND OR SHALLOW WATER (See Figure 2-A)
Put the headphones around your neck to keep them out of the
way while making the following adjustments.
1. Adjust the length and coil angle so
that the search coil rests flat on the
ground about 6 inches in front of and
slightly to the right of your right foot
(to the left of your left foot for left
handers.) Your arm should be straight
and relaxed with the handle grip held
firmly but comfortably. Remember,
as you increase the shaft length, you
also increase the strain on your wrist
and arm. The 1280-X is balanced
for comfortable searching in a tight
semicircle around the front of the
operator.
2. Leave enough slack in the coil cable
to allow the coil to swivel as far as
it can in either direction. The coil
wing nut should be tight enough to
prevent the coil from moving.
3. You should now be able to move into
your “search” position by leaning
slightly forward and raising the
search coil approximately 1 inch
above the ground. Your arm should
still be straight and the coil should
be parallel to the ground, about
12 inches in front of your foot. The
coil angle may have to be slightly
readjusted at this point.
FOR DIVING (see Figure 2-B)
The recommended setup for
underwater use is the shortest possible
stem length with the search coil
adjusted parallel to the sea bed or lake
bottom. Keep the headphones around
Figure 2. Setting up. When the
stem length is properly adjusted,
the 1280-X is balanced for
sweeping in a tight semicircle.
Always overlap your swings by at
least 50%
B. Short stem for diving
A. Extended stem for land or
shallow water

USING HEADPHONES
Using headphones (not included) improves battery life, and
prevents the sounds from annoying bystanders.
It also allows you to hear subtle changes in the sound more
clearly, particularly if searching in a noisy location. For safety
reasons, do not use headphones near traffic or where
other dangers are present. This device is to be used with
interconnecting cables/headphone cables shorter than three
meters.
SEARCH COILS
The 1280-X is available with either the standard 8 inch “Spider”
coil or the 10.5 inch “Spider” coil. As a general rule, the 8 inch coil
is preferred for tight spots, fast moving surf and high density trash
areas. For normal conditions however, the 10.5 inch coil will cover
a little more ground with each sweep and will give slightly more
depth 5 to 20 percent in air, less in soil, depending on target size
and mineralization. The most noticeable depth improvement will
be on large targets in non-mineralized soil.
The coils are not interchangeable since each instrument is
factory tuned to each coil. However you may have your 1280-X
retrofitted by the factory, phone or write for details.
