Fisher 1270 - Manual (Page 4)

NOTES
1. Subject to modification without notice.
2. Approximate.
3. PULSEGATE UNIPOLAR AUDIO PROCESSING.
Advanced Fisher circuitry which allows silent operation below the “Audio-Threshold
Tone” with no sensitivity loss. (See Note 6 also).
4. The 1270 is a “motion” detector while in the search modes, meaning that 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. The 1270 can operate silently with no “Threshold Tone” (See Note 3); however, in the
“maximum” sensitivity position, a low audible threshold is provided.
7. Fisher does not warrant suitability to specific use. Fisher shall in no event be liable for
any direct or, incidental, consequential or indirect damages.

are in for some exciting treasure hunting. Drop us a line if you
have any questions, comments or good finds to tell us about. In
the meantime... HAPPY HUNTING!
CONDENSED OPERATING INSTRUCTIONS
We recommend that you first read this entire operating manual
before taking your new 1270 out for a test. You’ll be more
knowledgeable, and have a better chance of finding more
treasure. But, we also understand the excitement of the “hunt”,
so here are some simple instructions for setting up the 1270.
Set the controls as follows:
NORMAL DISC = 5 (iron, lead, small brass & foil discrimination)
SILENCER switch = ON
IRON DISC switch = OFF
ALL METAL GROUND ADJ. = 0, OFF
(completely counter clockwise)
SENSITIVITY = 8
Turn the 1270 ON with the ON /OFF Volume control.
(adjust volume to a comfortable level)
Take your 1270 outside. There’s normally too much metal inside to per-
form a proper test. Hold the 1270 as shown in Figure 1, and slowly sweep
the search coil left and right while moving forward slightly with each
sweep. A slight motion is required for the 1270 to detect a target.
It is often helpful to bury a few known targets in the soil to get a “feel”
for how the 1270 responds to different targets at various sweep rates. Re-
member, at a DISC setting of 5, certain targets such as iron or aluminum
should be ignored.
When the 1270 “beeps”, you’ve passed over a metal target with the
search coil. Swing the 1270 left and right, then forward and back, making
an “X” over the “beep” area. Another method is to “bounce” the coil,
raising only about an inch off the ground, as you move the coil across the
target. The loudest audio response will occur in the center of the search
coil.The target will be directly below the center of the search coil. There are
exceptions to the center of coil pinpoint. For example, when a target is at
an angle or irregularly shaped. Because the 1270 is a “motion” detector,
with practice, this may be the only mode of pinpointing you will need.
To use the no-motion pinpoint mode, place the coil on the ground
away from the target, pull and hold the MODE TOGGLE SWITCH (on the
bottom of the housing). This switches the 1270 into ALL METAL no motion
PINPOINT mode. Keeping the search coil level with the ground, and mov-
ing the coil near the target you will hear an audio increase. Next, move
the 1270 in an “X” pattern over the target and stop where the loudest
tone is heard. This will be the center of your target, directly under the
center of the search coil.
