Fisher CZ-3D manual Depth Reading

DEPTH READING

Your CZ-3D will give you a quick and approximate depth reading of coin-size targets, usually within an inch.

1.Place the search coil lightly on the ground at least twelve inches away from your target area.

2.Press and hold the PINPOINT button.

3.Still pressing the PINPOINT button, bring the coil back over the target and pinpoint its location by stopping the coil over the point where you get maximum pitch, volume and needle response.

4.Place the search coil lightly on the ground directly over the target, and still pressing the PINPOINT button, note the position of the needle over the depth reading scale. For example, if the needle is midway between the four inch and six inch marks, your target is approximately five inches deep.

You will quickly realize that the depth reading procedure is just like pinpointing, however there is one very important difference: When pinpointing, where or when you press the pinpoint button is not real critical. It is often desirable to “detune” your target by pressing the button when the search coil is very close to your target and either on the ground or slightly above it. When taking a depth reading, however, it is important that the coil be placed lightly on the ground at least twelve inches away from the target (or any other metal) before pressing the PINPOINT button. Also, remember that while you can pinpoint just about any size target, depth reading is only accurate for coin size targets.
