This is a replacement of the standard search coil for the Garrett ATX metal detector. The 11x13" Mono coil provides greatest detection depth in most soil conditions. Garrett exclusive sliding mount design provides the advantages of a center-mounted coil (balance, easy tilting). Solid coil design is more resistant to impact. Front half of solid coil’s top surface provides a large, flat surface to spread a handful of dirt to sift for a tiny nugget. Ideal coil for prospectors and relic hunters for improved gliding/scrubbing over brush, rocks, etc.
