Note: Press the red button on the handle at any time during operation to automatically return the
pointer to 0.
b. Indoor testing
To learn how the detector reacts to different metals, you should test it before you use it the first
time. You can test the detector indoors or outdoors. You need to fine-tune the detector before every
use (see "Fine-tuning the Detector").
1. Remove any watches, rings, or other metal jewellery you are wearing and place the detector on a
wooden or plastic table.
2. Adjust the search coil's angle so the flat part faces the ceiling [P].
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 coin) about 2
inches (± 5cm) 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 (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.
c. 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 a 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 place the sample, sweeping the search coil in a side-to-side motion
[Q].
5. Try finding other metal in the area.
When you find a metal item, wait a few seconds after the tone stops before continuing, to allow
the detector time to reset (or, press the red button on the handle to return the pointer to the
centre of the vu-meter.
d. Search coil sweeping hints:
• Never sweep the search coil as if it were a pendulum. Raising the search coil while sweeping or at
the end of a sweep causes false readings [R].
• Sweep slowly - hurrying makes you miss targets.
• If the detector detects the material, it sounds a tone and the pointer moves to the type of
material if found. Set MODE to TR2 to determine the quality of the metal.
• If the detector does not detect the material, make sure you are moving the search coil correctly.
Notes:
• The detector responds with a strong signal when it detects most valuable metal objects. If a
signal does not repeat after you sweep the search coil over the target a few times, the target is
probably junk metal.
• False signals can be caused by trashy ground, electrical interference or large irregular pieces of
junk metal. False signals are usually broken or non-repeatable.
e. Fine-tuning the detector
When you become familiar with how your detector works, fine-tune it to make it more selective
in what it finds.
1) Adjusting SENSITIVITY [S]
To adjust the search coil's ability to detect objects at different depths in the soil, rotate
SENSITIVITY between MIN and MAX. For maximum detection depth, leave SENSITIVITY set
as high as possible. If the detector makes a "chattering" noise, decrease SENSITIVITY until
the "chatter" stops.
