OPERATION
The Fast Tracker is a MOTION metal detector; the search coil must be in motion over the targeted object in order for the machine to detect the object and emit a tone. Motion is required in order for the detector to automatically GROUND BALANCE. All soil and sand is different, containing varying amounts of naturally occurring minerals. As you sweep the search coil over the ground, your metal detector is constantly READING and AVERAGING the ground’s mineralization, in order to differentiate between the naturally occurring ground minerals and a metal target.
Adjust the SENSITIVITY
After powering the unit on, turn the left knob, SENSITIVITY, 100% clockwise. If the detector chatters or emits erratic sounds, reduce the sensitivity by turning the knob to the left. The detector will work well at the 2:00 or 3:00 position.
This adjustment is necessary due to
electromagneticinterference. Household appliances, lighting fixtures, outdoor power lines (overhead and buried) all emit electromagnetic fields.
Electromagnetic energy also occurs naturally in the environment. Your metal detector creates its own magnetic field; so you need to adjust your SENSITIVITY to compensate for any interference.
