Garrett 8.5 x 11 in DD Search Coil for AT Series
The Garrett 8.5 x 11 in DD PROformance, also called the Raider, is the all-round search coil for the AT series and the size that ships as the stock coil on the AT Pro and AT Max. It fits the Garrett AT Pro, AT Gold and AT Max through the 2-pin AT coil connector.
This is the coil to reach for when you want one size that does most jobs. The 8.5 x 11 in footprint balances ground coverage with target separation, and the Double D winding delivers depth on coin-sized and larger targets while running smooth in highly mineralized soil and on salt beaches. Whether you are replacing a worn stock coil or adding a spare, it is the dependable everyday choice. The whole coil is submersible to 10 ft.
GeoWork Supply ships the 8.5 x 11 in coil with its protective cover in the box. The AT Pro and AT Max owner's manuals are linked in the resources below.
