ˆOperation

Your RadioShack Metal Detector distinguish- es between ferrous and non-ferrous metals. Ferrous metals contain iron, while non- ferrous metals such as gold, silver, copper, platinum, aluminum, lead, and zinc do not.

When the detector senses a metallic object, the meter reading changes and the detector sounds one of three tones. The tone de- pends on what metal is detected. The higher the tone’s pitch, the stronger the detection.

PREPARING THE

DETECTOR

Turning On the Detector

Hold the detector in a comfortable position, then rotate MODE to the desired position.

VLF (Very Low Frequency) — to adjust TUNE and GROUND. (See “Adjusting Ground” on Page 9 and “Tuning the Detector” below.)

— to detect extreme differ- ences in metals, such as iron and gold. The difference between iron and gold shows on the meter (iron in the ferrous section, gold in the non-ferrous section).

TR2 (Transmit 2) — to detect finer distinctions between metals, such as aluminum and gold (see “Adjusting Discrimination” on Page 9).

Tuning the Detector

TUNE fine-tunes the balance between the de- tector’s receiver and transmitter circuitry to provide consistent pointer and tone indica- tions. Follow these steps to set TUNE.

1.Rotate VOLUME to the 10 o’clock posi- tion.

2.Set MODE to VLF.

3.Set GROUND, DISCRIMINATION, and

SENSITIVITY to mid-range.

4.Hold the search coil at least 1 foot away from the ground and any metal object, hold down the red button on the handle and slowly rotate TUNE until the analog meter pointer resets at or near 0.

As you search, you can fine-tune the detec- tor using the other controls (see “Fine-Tuning the Detector” on Page 9).

Note: Press the red button on the handle at any time during operation to automatically re- turn the pointer to the center of the analog meter.

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 in- doors or outdoors.

Indoor Testing

1.Remove any watches, rings, or other metal jewelry you are wearing, then place the detector on a wooden or plas- tic 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.Set MODE to TR1.

4.Move a sample of the material you want the detector to find (such as a gold ring
