Follow these steps to set TUNE:
1. Rotate VOLUME to the 11 o'clock position.
2. Set DISCRIMINATION to its midpoint.
3. Hold the search coil about 1 foot (30cm) away from the ground and any metal object, hold down the red button
on the handle, and slowly rotate TUNE left and right until the pointer on the vu-meter rests at or near 0, then
release the red button.
As you search, you can fine-tune the detector using DISCRIMINATION (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.
b. Testing and Using the Detector
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.
IMPORTANT: If the device emits a signal for nonferrous metals and none for ferrous metals, start the setting
procedure again. Do it slowly to make sure that the procedure is executed correctly.
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.
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. Rotate VOLUME to the 11 o'clock position.
4. Set DISCRIMINATION to its mid-point. Keep the red button on the handle pressed down and slowly turn the
TUNE button to the left and right until the needle of the VU meter indicates "0". Release the red button
5. 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, it sounds a tone and the pointer moves to the left (non-ferrous) or to the right
(ferrous) while the detector determines the type of metal it is detecting.
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").
