1. Move the search coil
When moving, you should move the search coil in a steady speed, not unsteadily.
Let the search coil be parallel with about 1/2 inch from the surface, not to swing it
like a pendulum to move it up and down from the ground(See Fig.12,13).
NON-MOTION mode
In water or on the uneven ground, it is difficult to move the search coil quickly.
You can choose the NON-MOTION mode, move the search coil slowly to detect. In
the areas where electromagnetic interference is relatively strong, the NON-MOTION
mode can also be selected. The detector gives out blue light and sound Du tone
occasionally, which means the NON-MOTION mode works normally. If it is found that
the detector doesn’t give out blue light and sound Du ton internally in the NON-MO-
TION mode, it means that there is metal, strong mineralizer or conductive soil
around the search coil. You can switch the MOTION-DISC button one or two times, to
reduce the interference.
Note: If the unit has no interval blue light and “DU” tone in NON-MOTION mode, you
can reduce the interference by switching the MOTION-DISC button one or two times.
