4.Sweep slowly to avoid missing tar- gets. Never raise the sweep coil while sweeping; sweep back and forth as if it was a pendulum (see Figure 18).

5.If the Tool detects the item, it sounds a tone and the pointer moves to the type of metal it found. After detect- ing metal, switch MODE TR1 to TR2 to determine the quality of the metal. If nothing was detected, try again (make sure the search coil is being moved properly).

6.The detector will respond strongly when it detects most valuable metal objects. If the signal does not repeat after being swept over the target a few times, the target is probably junk metal.

7.False signals can occur from elec- trical interference, large, irregular pieces of junk metal, or finding trash on the ground. False signals usually occur broken or are non-repeatable.

8.After finding a metal item, wait a few seconds after the tone stops before continuing; this allows the detector time to reset. You can also press the red button on the handle to return the pointer to the center of the viewmeter.

Fine Tuning

Once you practice with the unit, you can fine tune it to make it more selective in what is found.

Adjusting SENSITIVITY

To adjust the search coil’s ability to detect objects at different depths in the ground, rotate SENSITIVITY between MIN and MAX. For maximum detection depth, leave SENSITIVITY set as high as pos- sible. If the Tool begins to “chatter”, de- crease SENSITIVITY until the noise stops.

Adjusting GROUND

For accurate operation, it is criti- cal that you take the time to correctly set GROUND. GROUND tunes out false sig- nals from mineralized soil.

Figure 19

To set GROUND:

1.Set MODE to VLF and lower the search coil to 1/2 to 2 inches 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.Lift the search coil about 12 inches from the ground and press the red button on the handle. The pointer will return to the center. Repeat these three steps until the pointer stays close to the center each time you lower the search coil to the ground.
