When searching very trashing ground, it is best to scan small areas with slow, short sweeps. You will be surprised just how much trash metal and foil you will find in some areas. The trashiest areas have been frequented by the most people, and frequently hold the most promise for finding the most lost valuables. To make searching easier in very trashy areas, consider purchasing a 4inch Search Coil. The 4-inch coil’s narrower detection field can better distinguish between two objects in close proximity. Also maintain the search coil positioned just above the surface of the ground, without making contact with the ground. Making contact with the ground can cause false signals. False High Tones: If detector emits false high tones in DISCRIMINATION mode, rotate the GROUND BALANCE knob slightly counter clock wise. 20 IN THE FIELD TECHNIQUES - Pinpoint Mode GROUND BALANCING Before using the PINPOINT mode, it is necessary to ‘Ground Balance” your detector, this ground balancing adjustment offsets the effects of minerals and slats in he ground. To GROUND BALANCE your detector: 1. Using the ALL-METAL mode, find a patch of ground which is free of metal objects. You will use this section of ground to test the detector. The presence of any metal objects in this area will interfere with this procedure. 2. Begin with the ground balance KNOB in the PRESET position. 3. Lift the search coil waist high in the air. 4. Press the PINPOINT touch pad. 5. Lower the search soil to the ground, maintaining it elevated about 1/2 inch above the surface (be sure that this ground does not contain metal). • If the detector emits sound with the search coils 1/2 inch over the ground, further ADJUSTMENT IS NECESSARY. • If the detector remains silent with the searchcoil 1/2 inch over the ground, no further adjustment is necessary; the detector is “GROUND BALANCED” - Pinpoint Mode IN THE FIELD TECHNIQUES 6. If the detector emits sound with the coil over the ground in STEP 56, further adjustment of the ground balance KNOB is required as follows: • Lift the search coil waist high • Rotate the ground balance KNOB clockwise 1/16 of a turn • Press PINPOINT • Lower the search coil to the ground again If the detector still emits a tone, repeat the procedure. You are searching for the ground balance knob positiion where the detector is just silent. It is important to move the knob in small increments in order to find the first setting (moving clockwise) at which the detector remains silent. To insure yourself of the optimal adjustment, move the KNOB slightly counterclockwise from a silent-adjusted position to check for the most counterclockwise silent position possible. If the KNOB is over-adjusted in the clockwise direction, the detector can lose sensitivity. An over-adjusted condition can also cause the detector to sound off when the coil is lifted away from the ground. As your search takes you to different areas, verify the ground balance setting periodically using the above procedure. Within a geographical area, ground conditions can change. Varying elevation, proximity to water, and concentration of rock, sand or clay can all affect ground condition and sometimes require recalibrating with the ground balance knob. • If the detector remains silent with the search coil 1/2 inch over the ground, no further adjustment is necessary; the detector is “GROUND BALANCED” If the KNOB is over-adjusted in the clockwise direction, the detector can lose sensitivity.

Rather, user retuning is critical. The detector does not automatically adjust to changing ground and environmental conditions; the operator is required to make the adjustment. If the detector sounds a constant tone over all areas of the ground, retune the detector by pressing the PINPOINT button. Pinpoint is used to find the exact location of a target which was previously located and identified using the discrimination mode. As this mode does not require motion over the target, the user can move the coil more slowly and then narrow the detection field when near the target. How to Pinpoint Position the searchcoil an inch or two above the ground, and to the side of the target. Then press PINPOINT. Now move the searchcoil slowly across the target, and the sound will communicate the target’s location. As you sweep from side to side, and hear no sound at the ends of the sweep, the target is located in the middle of that zone, where the sound...
