TUNING

Tuning your IMPULSE is a simple but necessary step before

beginning your search. If you’re hunting underwater, the

following steps should be performed underwater.

1. Hold the coil up and away

from any metal.

2. Set the tuner full counter

clockwise, just before it clicks

into the “BATT TEST” position.

3. Set the VOLUME control

knob to “10.”

4. Hold the search coil 1 to 2

inches above the ground and

adjust the TUNER control knob

until the audio tone can just

barely be heard (usually one or

two bars on the LCD). Then fine-

tune it just a little bit louder than a faint tone (usually about

two bars).

5. Readjust the volume control to a comfortable level

when the search coil is passed over a large target.

6. You’ve now tuned your IMPULSE to its proper “threshold

tone” and you’re ready to begin searching. When you

move from dry sand to wet sand, or as ground

mineralization or temperature changes, you will have to

readjust your tuner slightly to maintain your threshold setting.

ON LAND OR SHALLOW WATER

Using good search techniques is every bit as important as having

a good detector.

1. Make sure your IMPULSE is properly tuned (see Tuning,

above) and the VOLUME control is adjusted before

beginning your search.

2. Begin by walking slowly, keeping the search coil as

close to the ground as possible.
