OPERATION

Clockwise rotate the "SENS" control to power on the detector.

1. "DISC" function

By adjusting the Discrimination control you will be able to ignore small pieces of metallic trash while detecting valuable targets. Discrimination points are determined by such factors as size, shape, depth, and type of metal and ground mineralization. Scatter some sample targets such as coins, pull tabs and small pieces of foil on the ground 1 to 2 feet apart.

(2) Turn the Sensitivity Control to clockwise full to set sensitivity to maximum.

(3) Turn the Discrimination control to counterclockwise full.

(4) Put the headset on and turn on the POWER. Hold the search coil about 2 inches above and parallel to the ground. Move it slowly over the samples and note the LED and Audio response as you pass over each one. Keep in mind that HP-1029 is a motion detector and responds only when the search coil is moving.

(5) Turn the Discrimination Control clockwise to several points of the white region and again pass over the targets. Repeat this process at yellow region and so on
to the red region. You will note that as you adjust the discrimination level, HP-1029 will reject some targets and continue to respond to others. You can determine the discrimination points per your needs. For example, the small nail discrimination may be at some point of the yellow region and the pull-tab discrimination point at red region.

(6) Some objects such as shallow bottle caps, bent pull tabs or trash less than 2 inches from the coil may be difficult to reject. The headset will give out a broken signal that will usually disappear if the search coil is raised slightly. The strong signal of a good target will just get weaker too when the coil is raised.

(7) HP-1029 will remain silent when some objects are rejected, however other objects may "snap, crackle and pop" as they are rejected. Those are normal responses
indicating that the powerful discrimination circuitry is doing its job.

(8) Large pieces of trash such as beer cans or jar lids may sound like good targets no matter what you do. With a little practice, however, you will be able to tell
the difference between a large target and a small coin sized object.

2 "SENS" function

Clockwise rotate the switch to turn on the power, go on clockwise rotating to increase the SENS generally, rotate to the full to set the highest SENS. High SENS should be used in the most detections.

Counter-clockwise rotate the switch to decrease the SENS. Fully counter-clockwise rotate the switch to turn off the power.
