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.
6.3 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.
6.4 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.
6.5 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.
2) Adjusting GROUND [T]
Setting GROUND takes a little time, but is critical for accurate operation. GROUND tunes out false
signals from mineralised soil.
1. Set MODE to VLF and lower the search coil to 1/2 to 2 inches (1 to 4cm) above the ground.
2. If the pointer swings to the right, turn GROUND to the left. If the pointer swings to the left, turn
GROUND to the right.
3. Raise the search coil about 1 foot (30cm) from the ground and press the red button on the handle.
The pointer returns to the centre.
4. Repeat Steps 1-3 until the pointer stays close to the centre each time you lower the search coil to
the ground.
After you set GROUND, the detector is set for the soil type of that particular site. Do not reset it until
you use the detector at a different site.
