Indoor testing
1. Remove any watches, rings, or other metal jewelry you are
wearing, then place the detector on a wooden or plastic table.
2. Adjust the search coil’s angle so the flat part faces the ceiling.
Note: Never test the detector on a floor inside a building. Most
buildings have metal of some kind in the floor, which might
interfere with the objects you are testing or mask the signal
completely.
3. Rotate VOLUME to the 11 o’clock position.
4. Set DISCRIMINATION to its midpoint.
5. Move a sample of the material you want the detector to find (such
as a gold ring or a coin) about 2 inches above the search coil.
Notes:
The search coil will not detect without motion. You must move the
object since you are not sweeping with the detector at this time.
If you are using a coin, the detector detects it more easily if you hold
it so a flat side is parallel with the flat side of the search coil (not the
edge).
If the detector detects the material, it sounds a tone and the pointer
moves to the left and the TARGET indicator indicates by red light (ferrous)
or to the right and the TARGET indicator indicates by green light
(non-ferrous) while the detector determines the type of metal it is
detecting.
If the detector does not detect the material, check the battery power and
verify that the search coil is properly connected. Also, you might need to
fine-tune the detector (see “Fine-Tuning the Detector” ).
