TESTING AND USING THE DETECTOR
To learn ho w the detector reacts to different metals, you should test it
before you use it the first time. You can test th e detector indoors an d
outdoors.
1. INDOOR TESTING
z
Remove any watches, rings, or other metal jewelry you are
wearing, then place the detector on a wooden or plastic table.
z
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.
z
Rotate VOLUME to the 11 o’clock position. Set DISCRIMINATION to
its midpoint. Rotate slowly left and right until the pointer on the view
meter rests at or near 0.
