6.1 Preparing the detector
1. Set BATT TEST to OPERATE.
2. Hold the detector in a comfortable position, then rotate MODE to the desired position. Set it to VLF to test
battery power and adjust TUNE and GROUND. (See "Fine-tuning the detector" and "Adjusting GROUND").
Set it to TR1 to detect extreme differences in metals, such as between in metals, such as between iron and
gold. The difference between iron and gold shows on the meter (iron in the ferrous section, gold in the non-
ferrous section). Set it to TR2 to detect finer distinctions between metals, for example between aluminium
and gold (see "Adjusting DISCRIMINATION") [N].
Follow these steps to set TUNE [O]:
1. Rotate VOLUME to the 10 o'clock position.
2. Set MODE to VLF.
3. Set DISCRIMINATION, GROUND and SENSITIVITY to their midpoint.
4. Hold the search coil about 1 foot (30 cm) away from the ground and any metal object. While pressing the
red button on the handle, slowly position TUNE until the pointer on the vu-meter rests at 0. Release the red
button.
As you search, you can fine-tune the detector using the other controls (see "Fine-Tuning the Detector")
Note: Press the red button on the handle at any time during operation to automatically return the pointer to 0.
6.2 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
( 5 cm) 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.
