Fisher Gold Bug Series 10-inch Solid Biaxial DD White Elliptical Coil

This 10-inch DD coil is compatible with the Fisher F5, Gold Bug, and Gold Bug Pro metal detectors. The coil uses a xxxx -on connector that fits these three models directly. It does not fit the Gold Bug II, which uses a different connector system. Before ordering, confirm your detector model matches one of the three compatible units listed. The DD biaxial design provides excellent depth and sensitivity across all three compatible models, making it a versatile upgrade for prospecting, relic hunting, and coin shooting.

The 10-inch DD coil provides deeper detection than stock coils, especially in mineralized soil. The DD geometry's main advantage is ground cancellation, so the depth gain is most noticeable in hot soil where stock coils force you to reduce sensitivity. In mineralized ground the larger coil footprint and biaxial winding work together to punch through ground noise and reach targets that smaller coils mask. In neutral soil both coil types perform well, but the 10-inch covers more ground per swing and offers better overall depth. The elliptical shape also improves target separation in trashy sites, letting you isolate good signals more effectively.

This coil is waterproof and handles shallow freshwater creeks, wet sand, and light surf without issue. The coil itself is fully submersible, so you can hunt creek beds, river edges, and wet beach sand safely. Check your detector's control housing waterproof rating before submerging the entire unit. The 6.6-foot cable is sealed and waterproof along its full length, and the xxxx -on connector provides a secure, moisture-resistant connection. Rinse the coil with fresh water after saltwater or mineralized water use to prevent corrosion on the connector threads and maintain long-term durability.

The cable is 6.6 feet long from the coil to the xxxx -on connector. This length works for most arm-mounted detecting configurations where the control box sits on the upper shaft. If you prefer a hip-mounted control box setup, the cable may feel slightly short depending on your detector's shaft length and your arm extension during swings. Most Gold Bug and F5 users mount the control box on the upper shaft and have no cable-length issues. The cable is durable and waterproof along its full length, with solid construction that resists kinking and wear during field use.

Yes, the 10-inch elliptical DD coil separates targets better than round concentric coils in iron-dense sites. The elliptical footprint is narrower along one axis, so when you sweep perpendicular to a line of iron targets, the coil isolates good targets near iron more effectively than concentric coils. In colonial relic sites where square nails cluster around buttons and buckles, the DD geometry lets you hear keeper signals that a concentric coil would mask. The improvement is most noticeable when you slow your swing and overlap passes. The biaxial winding also reduces ground noise, so you can focus on target signals rather than fighting mineralization chatter.

The DD coil's biaxial winding cancels ground mineralization more effectively than concentric coils, so you can run higher gain settings in Arizona caliche, Nevada desert washes, and other hot soil without constant ground chatter. In mineralized ground the 10-inch DD detects small gold nuggets deeper than stock coils by cutting through ground noise that masks faint signals. Ground balance your detector carefully at each new site, and expect to run manual ground balance adjustments as you move between soil types. The elliptical shape also helps you work around hot rocks and mineralized patches more precisely. For even finer gold sensitivity, consider the Fisher Gold Bug Pro metal detector with its high-frequency operation.

Yes, this coil is manufactured in the USA. Fisher manufactures this coil domestically, so you get quality control and direct access to Fisher's US-based technical support team if you encounter any issues. The solid construction and waterproof housing reflect Fisher's rugged manufacturing standards. The biaxial DD winding is precision-wound for consistent ground balance and target response, and the elliptical housing is built to withstand rocky terrain, brush, and repeated impacts during field use. The xxxx -on connector is machined for a secure fit and long-term reliability across thousands of detecting hours.

The coil weighs 14 ounces, which is light enough for all-day swinging without significant wrist strain. If you are covering large areas in gold country or working a relic site for extended sessions, the 14-ounce coil keeps fatigue low compared to heavier 11-inch or 12-inch coils. Balance the detector by adjusting the armrest position and shaft length to distribute weight evenly. The elliptical shape also reduces swing effort because the narrower profile cuts through air and brush more easily than round coils. Proper technique and balanced setup let you hunt comfortably for hours without excessive arm or shoulder strain.
