Fisher 1225-X manual False Signals

FALSE SIGNALS

between the beeps, or if you sweep at right angles to your original direction, you’ll receive a single beep directly over the target (except for the very shallow coin). One way to tell the difference between a coin and a nail is to set your discrimination at about 5. Most small nails will be tuned out while most coins will respond with a good, smooth signal.

6.EXTREMELY TRASHY SOIL: May result in a constant chatter or “snap, crackle and pop” with assorted, hard-to-find good signals.

SOLUTIONS: Increase the discrimination level. An even better solution is to try the optional 5 inch coil. You’ll be able to zero in on good targets much closer to junk.

7.DIGGING TOOL: If you’re carrying a metal digging tool in one hand, your 1225-X may sound off each time you swing the coil beneath it. SOLUTIONS: Hold it behind your back or up above your waist.

False signals may also occur in the Zero Motion Pinpointing mode. When in this mode the 1225-X detects all metals so you may pinpoint a piece of nearby junk instead of a good target. For this reason, you should always recheck your target area after recovering any target to insure that you haven’t missed anything.

You may also receive false pinpointing signals in highly mineralized soil. In this case, it is important to keep the coil parallel to the ground and at least an inch above it.
