FALSE SIGNALS
A “False Signal” occurs when something sounds like a good target, but is not. Your 1270 does a great job of discriminating, but bad “targets” with similar electrical characteristics can fool it. Large pieces of trash or items very close to the search coil will occasionally sound “good”. Experience is the best teacher. As you accumulate more hours with your 1270, you will soon learn how to distinguish “false signals”. Initially when you pass over a target, and get a good response, you will find that crossing over the target once or twice more, the signal will break up or completely disappear.
Here are some sources of false signals and the solution.
1.Electrical Interference: Caused by radio and TV towers, power lines, or other metal detectors.
SOLUTION: Move farther away from the source, slow down the sweep speed, or lower the sensitivity.
2.Highly Mineralized Soil: Soils with a high iron or salt content. SOLUTION: Reduce the sensitivity, raise the discrimination level, or if searching in the
3.Extremely Trashy Areas: May result in a lot of “chatter”.
SOLUTION: Utilize the SILENCER mode, adjust the discrimination level (the use of the IRON DISC mode can be very helpful here), or reduce the sensitivity. In some areas, a smaller coil will be beneficial to better achieve target seperation.
4.Metal Interference: The 1270 will pick up metal ABOVE and on the SIDE of the coil, as well as under. WATCH FOR: Large metal structures, your digging tool, and your coil cable hanging loose above the coil.
BATTERY REPLACEMENT
Your 1270 comes equipped with two
(+)inside the 1270 battery compartment. Slide the top of the battery in pushing against the copper contacts. Gently push the bottom of the battery into the compartment. Replace the Battery Cover.
