Fisher 1236-X2 warranty False Signals, Body or Hipmounting

FALSE SIGNALS

A “false signal” occurs when something that shouldn’t, sounds like a good target. Your 1236-X2 does an excellent job of ignoring junk, but it’s so sensitive to good targets that it can be fooled by bad targets with similar electrical characteristics. Large pieces of trash, for example, or even some kinds of bottle caps and pull tabs can fool you. Small pieces of trash less than 2 inches from the search coil will also sound good occasionally.

So what do you do about false signals? Well, 90 percent of them will sound suspicious to you after you’ve had some experience, and you’ll just ignore them. They may be very faint or very abrupt with static. Often when you go back over the same spot, a false signal will simply disappear. Other false signals may be very loud and sharp, but most of these will disappear if the coil is speeded up or raised slightly. Some shallow, large or irregular pieces of junk, however, will fool the 1236-X2 no matter what you do.

Here’s some other sources of false signals and what to do about them:

1.Detector Interference: Caused by nearby metal detectors operating at the same (or close) frequency. SOLUTION: Adjust the FREQUENCY control to the left or right of zero.

2.Electrical Interference: Caused by radio/TV stations, power lines, etc. SOLUTIONS: Move further away, lower the sensitivity, reduce the sweep speed.

Try changing the FREQUENCY control position. Wrap the search coil cable tightly around the stem.

3.Highly Mineralized Soil: Usually causes constant static or good target sounds. SOLUTIONS: Lower the sensitivity, increase the discrimination. Raise the search coil until false signals disappear and sweep at that height.

4.Wet Sand: Same as highly mineralized soil.

BODY or HIPMOUNTING

1.Disconnect the search coil cable from the control housing and unwind all but the last 12 inches or so from the upper handle. Secure the lower end of the cable with a Velcro® strap at least 12 inches up from the coil.

2.Remove the control housing from the hand grip by holding the grip with one hand and sliding the housing toward you with the other.

3.Attach your belt to the control housing by slipping it through the slots on the underside of the control housing.

4.Reconnect the search coil cable to the control housing.

5.The control housing can also be mounted on on the optional Fisher Chest Harness. It is especially important that the cable connector be installed tightly (hand tightened only) to prevent false signals during body-mount use.

Note:

For belt mounting, left handers should wear the housing on their right hip and right handers should wear it on their left hip.

  Once removed from the stem, the control box can be hip or chest mounted leaving only the stem and search coil to swing.
