Fisher 10-inch DD White Elliptical Search Coil for F75 and F70 Metal Detectors

The Fisher 10-inch DD White Elliptical coil is compatible with the Fisher F75 and Fisher F70 metal detectors, as well as the Teknetics Patriot. All three models use the same xxxx -on coil connector, so this coil mounts directly without adapters. If you own one of these detectors and need a narrower search profile for trashy sites or shallow water hunting, this coil is a direct swap for the stock round coil. The DD configuration and elliptical shape make it particularly effective in mineralized soil and tight spaces where target separation is critical.

The coil measures 10 inches by 5 inches (25cm by 13cm) in an elliptical footprint. Fisher does not publish the weight in the product documentation. The elliptical shape is lighter and easier to swing for extended periods than a 10-inch round coil of equivalent coverage area, reducing arm fatigue on all-day hunts. The solid construction ensures durability while maintaining a balanced feel when mounted on the F75 or F70 lower shaft, making it comfortable for extended prospecting, relic hunting, and coin shooting sessions.

The Fisher 10-inch DD coil is waterproof and built with sealed solid construction, making it suitable for shallow water hunting in creeks, river edges, wet sand, and rain. Fisher does not specify a depth rating in feet or meters, so treat it as splash-proof and submersible to shallow depths rather than a fully submersible coil rated for deeper wading. The xxxx -on connector is designed for water use, and the coiled cable resists water intrusion at the attachment points when properly installed on your F75 or F70.

The DD (biaxial) configuration on this Fisher coil provides better target separation in trashy ground than concentric coils. When you swing over a nail and a coin lying close together, the DD coil's narrow detection pattern lets you hear the coin signal separately as the field passes between the two targets. DD coils also handle mineralized soil and saltwater beaches better than concentric designs, making them the stronger choice for iron-heavy sites and variable soil conditions. The 10x5-inch elliptical shape further enhances separation by reducing the width of the detection field.

The 10x5-inch elliptical shape excels in trashy parks, old homesteads with dense iron scatter, shallow water hunting in creeks, and any site where you need to maneuver between obstacles or isolate targets in tight clusters. The narrow 5-inch width lets you swing between fence posts, tree roots, and rocks without the coil catching, while the 10-inch length maintains decent ground coverage. Relic hunters working iron-contaminated sites use elliptical coils to separate good targets from iron fragments. Coin hunters in urban parks use them to cut through pull-tab and foil layers to reach older silver underneath.

The Fisher 10-inch DD coil is suitable for gold prospecting, particularly in areas with iron trash and mineralized soil where the DD configuration helps reduce ground noise. The elliptical shape lets you work between sagebrush and rocks in Western desert washes and navigate tight spaces in goldfields. This coil is listed for prospecting use along with relic hunting, coin shooting, jewelry hunting, and shallow water hunting. The 10-inch size provides good depth and ground coverage when you are hunting nugget patches or working old mining camps where you need to separate targets from iron trash.

The Fisher 10-inch DD coil uses a xxxx -on connector that attaches to the coil mount on your F75 or F70 lower shaft. The xxxx -on design locks more securely than push-fit connectors and resists loosening during long hunts on rough terrain. The coil is designed for direct mounting without adapters, making it a straightforward swap from your stock coil.
