Tips for Searching in Different Environments

There are many factors which influence the sensitivity and accuracy of detecting objects, including the angle, depth, size and oxidation

of the target object. Various soil or seawater conditions, and also electromagnetic and electrical interference surrounding the target can also affect readings. Other metal detectors in the area will also cause interference, so when there is more than one unit in use, be sure they are at least 10 yards apart. Some ways to help increase success are:

1.If there is interference from similar metal detectors in your searching area, lower the SENS setting to stop the interference.

2.If there is interference from electrical cables, TV, radio, or other electrical devices in your searching area, lower the SENS setting.

3.When searching in highly mineralized areas, the unit may sound even if there is no metal. Lower the SENS setting, set the DISC to high and increase the distance of the Search Coil from the ground until the false signal disappears. To set the DISC setting, place a test metal object

in highly mineralized earth or wet sand and adjust the setting before beginning.

4.When searching in a trash area, set the DISC to the middle setting so that the unit can reject most invaluable metals such as nails, bottle caps, cans, and small pieces of iron.

5.Move all metal digging tools when searching.

6.The SENS level is generally opposite the DISC setting. The higher the sensitivity level is, the worse the discrimination will be. You can lower the sensitivity to have better discrimination.
