Failure to follow the major rules will most likely result with errors. Do not turn or rotate the antenna or Super Sensor - this means that when the antenna is facing one direction, it must remain in that direction.

    • To use the Super Sensor with the eXp 4500, simply connect it to the main unit. Always hold the antenna vertical to the ground in your hand, whereby the cable should come out at the upper end of the antenna.

  • Page 91: Super Sensor Training Marks

    By putting several lines or marks on the Super Sensor (a colored electrical tape as example), others can easily see if the unit is being rotated. The user has the arrow on the top of the Super Sensor to aid in keeping the unit straight. OKM GmbH www.okmmetaldetectors.com...

  • Page 92: Super Sensor Orientation

    When the grip is too strong then the Super Sensor will not be vertical and it can be uneven like those on the right side of the image. The orientation of the antenna should not be changed during the complete measurement! OKM GmbH www.okmmetaldetectors.com...
  • Page 93 The other users need to ensure that the Super Sensor is not rotating or tilting and that it is remaining the same height over the ground. OKM GmbH www.okmmetaldetectors.com...
  • Page 94 When looking for traditional buried objects this method is also used to ensure that the item is actual. The only difference is that with a traditionally buried object that the signal values will be greatly increased for the actual object(s). OKM GmbH www.okmmetaldetectors.com...
