Garrett 14" X 11" DD Reaper Search Coil for ACE Series Metal Detectors defragmenter up to 15 hours runtimeThe Garrett 14" x 11" DD Reaper search coil is a waterproof elliptical coil built for ACE series detectors hunting large open areas. ACE owners covering farm fields, pastures, and cache sites gain 25% more ground coverage per swing compared to the stock 8. 5" x 11" DD coil. The larger footprint reduces the number of passes needed to grid a site and improves detection depth on medium to large targets while preserving sensitivity to smaller objects.
