The Coil/Rx control changes the search pattern and sensitivity
of the coil. This improves the versatility and characteristics of
GP Series and Commander Double D coils. This is achieved by
altering the pattern of transmit (Tx) and receive (Rx) fields of
the coil, and how the control box interprets the response. Each
switch position changes the electromagnetic field of the coil,
thus giving better performance in certain situations.
Coils not specifically designed by Minelab may behave
erratically, or be ineffective, in either the Mono or
Cancel positions.

You will need to re-Ground Balance every time you select a
new position for the ‘Coil/Rx’ switch.
Caution: Iron Reject will not work when using a
Monoloop coil.
Iron Reject will give the best results when used in
conjunction with the specially designed Commander
Double D coils.
