AVSL 499.921 PROFESSIONAL METAL DETECTOR - Manual (Page 10)

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. Set MODE to TR1.
4. 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 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 (not the edge) is parallel with the flat side of the search
coil.
If the detector detects the material, the NON-FERROUS and FERROUS
indicators flash and the pointer moves to FERROUS or NON-FERROUS
while the detector determines the type of metal it is detecting. If it detects
non-ferrous metal, it also sounds a tone.
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” on Page 9).
Outdoor Testing and Use
1. Find an area on the ground outside where there is no metal.
2. Place a sample of the material you want the detector to find (such as a
gold ring or a coin) on the ground. (If you are using valuable metal such
as gold to test the detector, mark the area where you placed the item,
to help you find it later. Do not place it in tall grass or weeds.)
3. Set MODE to TR1.
4. While holding the search coil level and about 1-2 inches above the
ground, slowly move the search coil over the area where you placed
the sample, sweeping the search coil in a side-to-side motion.
