ABOUT YOUR DETECTOR

Your 1212-X is more proof from Fisher Research Laboratory that
a good metal detector doesn’t have to be complicated and
expensive. No frills but a lot of performance features that really
count: automatic VLF-ground rejection, automatic tuning,
variable trash rejection, headphone jack, built-in speaker and a
deep-seeking, lightweight, 8 inch, search coil. Best of all, it does
what a metal detector is supposed to do—it ignores ground
minerals and trash as it detects valuable buried targets.

One knob operation. Just pick it up, set your trash rejection level
and start searching. No tuning, no meter, no gimmicks.

Performance. If you’ve tested other detectors in this price range,
you’re in for a pleasant surprise. In fact you may find that your
1212-X goes deeper and ignores trash better than some detectors
costing much more.

State of the art. Engineered by the world’s oldest and proudest
name in metal detectors. Patented, double derivative
electronics provide up to 30 hours of silent, no drift operation on
a single 9 volt transistor battery.

Read this instruction manual from cover to cover and treat
your 1212-X as you would any high quality precision instrument.
Drop us a line if you have any questions, comments, or exciting
1212-X stories. In the meantime . . .

Happy Hunting!

SETTING UP

The 1212-X comes to you just about ready to use. The only
adjustment required is the angle of the stem. Take a look at
page 3 and familiarize yourself with the parts of the 1212-X
before proceeding.

1. Unpack your new 1212-X carefully. Save the
carton and inserts—they may come in handy for
future storage or shipment.

2. Note that the search coil cable is permanently
attached to the control housing. Be careful not to
put any undue strain on it.

3. Take a look inside the locknut on the upper stem.
Note the yellow locking pad on the left-hand side
and loosen the locknut by rotating it fully
counterclockwise.

4. Slip the lower stem into the upper stem, tighten and
loosen the fit by turning the locknut.

5. Adjust the stem length (using the locknut) and the
coil angle (using the nylon wing nut) 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 your grip
held loosely.

REMEMBER: THE LONGER THE SHAFT, THE MORE YOU
WILL HAVE TO BEND YOUR ELBOW AND THE
SOONER YOUR ARM WILL GET TIRED. THE 1212-X IS
BALANCED FOR COMFORTABLE SEARCHING IN A
TIGHT SEMICIRCLE AROUND THE FRONT OF THE
OPERATOR.

6. With the stem length properly adjusted, remove
the search coil from the lower stem (by removing
the Delrin bolt and wing nut). Wind the cable
loosely around the upper and lower stems and
reinstall the search coil.

CAUTION: MAKE SURE THE CABLE IS NOT PULLED
TIGHT AT THE CONTROL HOUSING AND THAT YOU
HAVE ENOUGH SLACK AT THE SEARCH COIL TO
ADJUST IT TO ANY ANGLE.

7. With the shaft length and coil angle
properly adjusted, you should be
able to move into your “search”
position (as shown in Figure 2) by
leaning forward very slightly and
raising your arm (still straight) until the
search coil is about 2 inches above
the ground and 12 inches in front of
your foot. The search coil should be
parallel to the ground and may have
to be slightly readjusted at this point.

1. ON/OFF - TRASH REJECTION CONTROL: Power is

turned off at the full counter clockwise “OFF”
position. All metals are detected when turned on
to zero. Most small pieces of metal trash are
rejected at the maximum level of ten. Most ground
minerals are ignored at all settings.

2. STEREO HEADPHONE JACK: Located on the right side
of the control panel, this jack accepts most stereo
and mono headphones with 1/4” diameter plugs.
When used, the speaker is automatically
disconnected. A headphone can be very helpful
when hunting in noisy areas or detecting faint signal
on small, deep targets. CAUTION: Since the 1212-X
has a fixed volume setting (loud), always use
headphones with individual volume controls
adjusted to a comfortable level. Also, If you use a

stereo headphone, make sure the stereo/mono
switch is in the “stereo” position.
