    CONTROL PANEL SENSITIVITY These controls change the detector’s sensitivity; higher settings enable detection of deeper targets. At power-up, the detector is pre-set to 75% of maximum sensitivity. At minimum, the sensitivity is 35% of maximum. With each press of the touch pads, the sensitivity level is displayed on the bar graph on the left of the display.
  • Page 8 CONTROL PANEL (continued) PINPOINT Press and hold to activate this feature This is a static detection mode; no coil motion over the target is required to detect metal while pinpoint is depressed. This feature most effective pinpointing the exact location of small buried objects.

    4-TONE AUDIO SYSTEM While the LCD (Liquid Crystal Display) is very accurate in identifying buried objects, the user in the field does not always maintain the display screen in his field of vision. Therefore, we have incorporated an audio feedback mechanism to alert the user to the nature of buried objects.

    To manage chatter, which is most likely from electrical interference: until the chatter stops. Try sweeping it over the ground. If the F2 chatters while held still, or held up in the air, it may be much quieter when sweeping over the ground. SEVERE GROUND CONDITIONS A secondary use for the Sensitivity Control is to reduce false detection signals caused by severe ground conditions.

    SEARCH TECHNIQUES (in DISC mode) After detecting a target, do the following: WRONG Walk around the target in a circle. While circling target, continue sweeping searchcoil across the target. Sweep once every 30° or 40° of CORRECT the circle. If the tone does not change and the target ID value is consistent as you circle the target, you can be highly...

  • Page 14: Target Pinpointing

    TARGET PINPOINTING (no-motion PINPOINT mode) After you have identified a target using a motion mode of detection, press to identify the target’s exact location. This technique can yield more information about the target’s shape and size and also find its exact location to facilitate excavation. Position the searchcoil just barely off the ground, and to the side of the target.
