Garrett Axiom 16" x 14" DD Search Coil for Gold Prospecting

The Garrett Axiom 16" x 14" DD search coil is compatible exclusively with the Garrett Axiom detector. This coil uses the proprietary Double-D construction and connector system designed specifically for the Axiom platform. Axiom owners gain three coil size options in the DD lineup: the 11" x 7" for maximum target separation in trashy patches, the 13" x 11" for balanced coverage in moderate-trash ground, and this 16" x 14" for maximum area coverage in open washes and hillsides. All three coil sizes ship with protective covers and maintain waterproof integrity for wet-ground prospecting, giving you flexibility to match coil size to ground conditions.

The 16" x 14" DD coil covers more ground per swing than the 13" x 11" coil, making it the better choice for wide-open desert washes and hillsides where nuggets scatter across expansive terrain. Both coils use the same Double-D construction for strong sensitivity on small gold, but the larger footprint lets you prospect big areas faster when target separation isn't a limiting factor. The 13" x 11" coil becomes the better option when you're working patches with moderate trash density or bedrock crevices where multiple targets cluster within a few inches of each other. Our team switches between the two sizes based on ground conditions: the 16" x 14" stays on the detector in open Nevada washes, and we swap to the 13" x 11" when we move into tighter benches or old dig sites.

The Garrett Axiom 16" x 14" DD coil is fully waterproof and built for submersion in creek beds, flooded washes, and wet hillside seeps. The coil housing and cable connection maintain seal integrity when you're working seasonal runoff channels or prospecting wet ground after storms. Axiom prospectors running the coil in Arizona and Nevada creeks report no seal failures or water intrusion after repeated wet-ground use. The included coil cover protects the housing from rock abrasion in creek beds, extending coil life in harsh prospecting conditions.

The Garrett Axiom 16" x 14" DD coil ships with a protective coil cover included in the box. The cover fits the semi-elliptical geometry of the 16" x 14" footprint and protects the coil housing from rock abrasion, brush contact, and impact damage during prospecting. Axiom operators working rocky desert terrain or bedrock exposure benefit from running the cover full-time because pulse-induction prospecting often involves dragging the coil across abrasive surfaces. The cover material is durable enough to handle repeated contact with sharp rocks without tearing, and it doesn't interfere with detection depth or sensitivity.

DD-FC stands for Double-D Focused Core, a coil construction Garrett developed for the Axiom pulse-induction platform that concentrates the electromagnetic field for stronger response on small gold targets compared to traditional mono coils. The Double-D configuration creates two overlapping detection fields that intersect in a narrow centerline, giving you better target separation in mineralized ground than a circular mono field would provide. The Focused Core element tightens the field concentration along that centerline, boosting sensitivity on sub-gram nuggets that larger mono coils miss. Axiom prospectors working patches with fine gold report better small-target response from DD-FC coils than from the mono coils they ran on previous pulse-induction detectors. The technology works across all three Axiom coil sizes, so you're not trading sensitivity for coverage when you step up to the 16" x 14" footprint.

The 16" x 14" DD coil works in trashy patches, but the larger footprint makes target separation more challenging when multiple targets cluster within inches of each other. Axiom prospectors working old dig sites or bedrock crevices with dense trash get better results from the 11" x 7" coil because the smaller footprint isolates individual nuggets that the 16" x 14" coil would blend into a single signal. The 16" x 14" coil excels in open washes and hillsides where trash density is low and the expanded coverage lets you prospect more ground per hour. If you're working a mix of open ground and trashy patches, consider running the 16" x 14" coil in the open areas and swapping to the smaller coil when you move into concentrated trash zones.

The Garrett Axiom 16" x 14" DD coil is backed by manufacturer warranty coverage when purchased from an authorized dealer like Serious Detecting. For specific warranty terms, coverage details, and service information, contact Garrett directly or refer to the warranty documentation included with your coil. The warranty typically does not cover physical damage from impact, abrasion, or improper storage, so running the included coil cover protects your investment in rocky prospecting terrain. Serious Detecting ships every Axiom coil with full warranty documentation, and our team can help coordinate manufacturer support if you need assistance. Proudly designed, engineered, and made in the USA at Garrett's Garland, Texas facility and built to the same standards as Garrett's flagship detectors.
