2. Approximate.

3. Pulsegate Unipolar Audio Processing. Advanced Fisher circuitry which allows silent

operation below “audio threshold tone” with no loss in sensitivity.

4. The 1212-X is a “motion” detector while in the search mode. The search coil must be
moving at least slightly to detect a target.

5. Electro-Static-Insulated to eliminate certain types of false signals.

6. Use of headphones may increase battery life up to 100%.

Where To Use Your Metal Detector In The

National Forest and Federal Lands—Metal detecting is allowed

only by special permit acquired from the federal government.
Each area has a district ofce.

Corps of Engineers, Lakes, Shorelines and Lands—Permission has

been granted only on predisturbed sites, such as beaches and

attached swimming areas. New Corps lakes and lands must be
okayed by the main ofce of the Army Corps of Engineers. Each
area has a district ofce.

State Parks and Lands—Some state parks are open to metal

detecting, but some are not. Always check with the park ranger
before attempting to use your detector.

Bureau of Land Management (BLM) Lands—Some areas are

open for metal detecting, and some are not. Always check with
the district ofce.

City or County Park Lands—Most are open to metal detecting

unless notice is given by a sign or city ordinance. When in
doubt, always check with the city’s Parks and Recreation
Department.

Public School Grounds—Most are open to metal detecting

unless notice is given by a sign, city ordinance, law enforcement
ofcial, or school employee. You should always check with the
school ofce rst.

Privately Owned Lands (Private Property)—Permission required.

And it is always best to have the permission in writing.
Historically Marked Lands or Sites—Metal detecting is not
allowed. Don’t even think about it.

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 nd 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!
