10 x 12" Inch DD COIL for the Garrett ATX
Garrett 10 x 12″ inch DD Search Coil for the Garrett ATX Metal Detector. This is the standard waterproof stock coil for the Garrett ATX. The unique configuration allows for greater detection sensitivity in the center ring of the coil, especially on small targets like gold nuggets. The Iron discrimination feature works only with ATX DD coils, not with the Mono design.
DD Coils also have better target separation capabilities and do better overall in highly mineralized soil. While the mono coil design "might" edge the DD coil out in depth in "some" areas and one can detect off the edge of the coil. They both have their strengths and weaknesses.
