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 searchcoil 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 searchcoil 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 searchcoil
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
The 1280-X is supplied with permanently attached waterproof
headphones. They cannot be removed by the user. If they are
damaged or need service, you must return the entire detector
assembly to the factory repair or replacement.
Headphones 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.
SEARCHCOILS
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.
