If you want to cover more ground or find larger targets, Garrett has designed a 14" x 11" coil compatible with your AT series metal detector.

Heard of Super Separation tech? This highly sensitive Cors 5" DD Point coil for AT Max has it. Fully waterproof for use in all conditions.

This Garrett AT Pro Bundle is complete with the original 11" coil and a 5x8" coil for working in smaller areas or trashy parks.
