The Garrett Axiom 13" x 11" DD-FC search coil is a waterproof Double-D accessory built for Axiom pulse-induction detector owners prospecting in mineralized ground where mid-sized coverage balances target separation and depth penetration. Axiom operators working open washes or hillside patches where nuggets scatter across wider ground gain better area coverage from this semi-elliptical geometry than the smaller 11" x 7" coil provides, while maintaining tighter target separation than the 16" x 14" option. The DD-FC (Double-D Focused Core) design delivers detection performance that exceeds traditional mono coils on small gold targets, letting you cover more ground per swing without sacrificing sensitivity on sub-gram nuggets.
What's Included with the Garrett Axiom 13" x 11" DD Coil
- Garrett Axiom 13" x 11" DD-FC search coil
- Protective coil cover
Why Garrett Axiom Owners Reach for the 13" x 11" DD Coil
- Balanced coverage for open-ground prospecting: the 13" x 11" semi-elliptical footprint covers more area per swing than the 11" x 7" coil while maintaining better target separation than the 16" x 14" option in patches with moderate trash.
- Focused Core technology boosts sensitivity on small gold: the DD-FC construction concentrates the electromagnetic field for stronger response on sub-gram nuggets that larger mono coils miss.
- Waterproof construction supports wet-ground prospecting: run the coil through creek beds and flooded washes without worrying about seal integrity.
- Included coil cover protects against rock abrasion: the durable cover ships in the box, extending coil life in rocky terrain.
- Proudly manufactured in the USA: engineered to the same standards as Garrett's flagship detectors.
Wider Coverage in Mineralized Gold Fields
Open Wash and Hillside Prospecting
The 13" x 11" footprint gives Axiom operators working open desert washes or hillside patches faster ground coverage than the stock 11" x 7" coil. When nuggets scatter across wide areas with moderate mineralization, the mid-sized geometry lets you cover more ground per hour while the DD-FC technology maintains strong response on small targets. Prospectors working patches where trash density is low gain the speed advantage of a larger coil without the target-masking drawbacks of the 16" x 14" option. The semi-elliptical coil geometry concentrates the detection field along the long axis, giving you better depth on deeper nuggets in open ground.
