Setting Up - Fisher M-Scope 1280-X Aquanaut Operating Manual

MAINTENANCE
CLEANING
Hose down your 1280-X with clean fresh water whenever you've
had it on the beach or in the water. Pay particular attention to the
following areas:
1. Stem adapter. Sand or dirt between the coil "ears"
and stem adapter will literally grind away the ears
and adapter.
2. Headphone. The ear pads may be removed, rinsed
and squeezed out to remove any seawater salt build
up. Rinse out the cups to keep the vent holes clear.
NOTE: These vent holes MUST be kept clear when
diving to equalize ear pressure.
3. Between the upper and lower stems. Sand, silt or
fine dirt will cause the lower stem to freeze up.
4. Control Panel. Rinse the area under the three knobs
thoroughly.
5. Battery Cover. Always clean and dry the area
around the battery cover seal before opening.
BATTERY COMPARTMENT
1. Remove the battery cover and check for water
after each use in water.
2. Keep the sealing surfaces of the battery cover and
control housing clean and free of scratches and nicks.
Remove and clean the neoprene gasket frequently.
Lubricating the gasket is not recommended. Cleaning
the gasket should only be done by using mild soap
and warm water. Do not use petroleum jelly or silicone
grease at any time.
STORAGE
Remove the batteries from the battery pack when storing your
1280-X for extended periods to prevent damage caused by battery
leakage.
Never leave your 1280-X in an auto trunk or even in a closed
passenger compartment during hot weather. Temperatures in
excess of 120°F are possible which could damage electronic
components and ruin the batteries.

SETTING UP

FOR LAND OR SHALLOW WATER
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
A. Extended stem for land or
shallow water
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
B. Short stem for diving
T h e r e c o m m e n d e d s e t u p f o r
underwater use is the shortest possible
Figure 2. Setting up. When the
stem length with the search coil
stem length is properly adjusted,
adjusted parallel to the sea bed or
the 1280-X is balanced for
lake bottom. Keep the headphones
sweeping in a tight semicircle.
Always overlap your swings by at
around your neck, off your ears, while
least 50%
descending or ascending.
