Fisher 1236-X2 warranty Control Functions, Operating Tips

CONTROL FUNCTIONS

1.SILENCER: When the toggle switch is flipped ON, the 1236-X2 runs in the 3rd derivative SILENCER discrimination mode, eliminating the annoying “pops” and “clicks” heard when searching in extremely

trashy areas. Flipping it to OFF, the 1236-X2 runs in classic 2nd derivative discrimination mode.

2.DISC: This control sets the discrimination level. At a setting of 0, all types of metal are detected. At higher settings, less conductive objects and trash are rejected. When the DISC control is fully rotated (counterclockwise) to the IRON preset, the 1236-X2 is set to reject common trash and nails.

Note: The DISC Control has no effect in PINPOINT mode.

3.SENSITIVITY: This control adjusts sensitivity to targets and ground minerals. The higher the setting, the deeper you’ll detect. However, you will also pick up more false signals in highly mineralized or trashy soil. At a setting of 10, a slight amount of audio threshold is provided so the faintest of targets can be heard. At the BATTERY setting, a battery test tone is sounded.

A loud tone indicates good batteries. A faint tone

OPERATING TIPS

1. We’ve already said it, but it bears repeating: TAKE

YOUR TIME AND OVERLAP YOUR SWEEPS.

2. Use good headphones. You won’t miss faint

targets, you won’t attract unwanted attention and

you won’t bother others.

3. Practice pinpointing. There’s nothing sacred

about the methods described in this manual. Many

1236-X2 users have developed their own pinpointing

methods.

4. Always BURY A COIN when working in unfamiliar

territory, and check it at different discrimination and

sensitivity levels. There may be some sensitivity loss

at higher levels of discrimination. The greater the

ground mineralization, the higher the sensitivity loss.

For example, you may be able to detect a penny at

6 inches with zero discrimination, but no deeper than

4 inches at the pull-tab discrimination point.

5. The 1236-X2 is an easy detector to use, but if you’re

having trouble with any aspect of its operation

(pinpointing, searching, false signals, etc.) go back

and reread the part of this manual relating to your

problem.

6. If a target gives a strong response in the search

mode but no response in the NO-Motion Pinpoint

mode, you may have “tuned out” your target (and

all others) by pushing the PINPOINT button over

another piece of metal. If you suspect this may be

the case, move the search coil to another spot

before pressing the PINPOINT button again.

7. When in doubt about the possible identity of a

target, dig it up.
