or a coin) about 2 inches 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 point- er moves to FERROUS or

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 LOW BATT indicator and verify that the search coil is properly connected. Al- so, 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 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 place 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 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.

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.

•Sweep slowly; hurrying makes you miss targets.

If the detector detects the item, it sounds a tone and the pointer moves to the type of metal it found. When you detect metal, switch MODE TR1 to TR2 to deter- mine the quality of the metal.

If the detector does not detect the mate- rial, 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 areas containing large amounts of trash, electrical interference, or large irregu- lar pieces of junk metal. False signals are usually broken or non-repeatable.

5.Try finding other metal in the area. When you find a metal item, wait a few seconds after the tone stops before con- tinuing to allow the detector time to reset (or, press the red button on the handle to return the pointer to the center of the analog meter).
