  • LENGTH: 55"
  • WEIGHT: 3 lbs
  • DEPTH: pending type of metal and density of soil approx. 6", but ideal for finding objects 1" to 4".
  • SEARCH LEVEL: 2" above ground, 12" in front of you
  • FREQUENCY: 4.2 kHz Unipolar
  • POWER: 9 volt batteries
  • HOW TO SEARCH:
  • 1. To start off set the search coil about 2 inches above the ground and 12 inches in front of your foot. Search slowly and systematically, sweeping in a tight semicircle. Keep the coil parallel to, and as close to the ground as practical.
  • 2. ON/OFF - TRASH REJECTION CONTROL: Power is Turned off at the full counter clockwise "OFF" position. ALL metals are detected when turned on to zero. Most small pieces of metal trash are rejected at the maximum level of ten. Discrimination points are determined by such factors as size, shape, depth, type of metal and ground mineralization. Audio responses over 1 inch deep targets with search coil sweeping 2 to 3 inches above ground.
  • 3. HOW TO SET THE DETECTION SENSITIVITY: Increase the TRASH REJECTION control to a setting of 3 and pass over test targets, find a similar object which you are trying to find to set the sensitivity as a test object. Repeat this process at settings 4, 5, 6 and so on to 10. You will note that as you increase the level of trash rejection, will reject some targets and continue to respond to others. You have now determined the discrimination points for the rejected objects. For example, the small nail discrimination point may be at 4 and a ring discrimination at 6. Note that as you increase the discrimination level, you progressively eliminate more targets including some good ones, such as nickels and gold rings.
  • 4. It will remain silent when some objects are rejected, however, other objects may snap, crackle and pop as they are rejected. This is a perfectly normal response indicating that the powerful discrimination circuitry is doing its job. Large pieces of trash such as beer cans or jar lids may sound like a good target no matter what.
