What is in the box with the Fisher 10COIL-GB2 coil
Fisher's standard contents for the 10 inch Gold Bug 2 coil (Fisher part 10COIL-GB2)
- Fisher 10 x 5 inch solid concentric elliptical search coil with screw-on connector
Which detectors the 10COIL-GB2 fits
- Fisher Gold Bug 2 built before July 2026 (screw-on coil connector)
Fisher's Gold Bug 2 manual lists interchangeable elliptical searchcoils in 6.5, 10 and 14 inch sizes. Fisher sells the 10 inch coil in two versions: 10COIL-GB2 for Gold Bug 2 detectors built before July 2026, and 10COILGB2-5P with the 5-pin connector for units built from July 2026. Check the coil connector on your Gold Bug 2 before ordering, because the two versions do not interchange. The Gold Bug, Gold Bug Pro and Gold Bug DP use their own coils. Every Fisher part sorted by detector is on our Fisher parts and accessories by detector model page.
When to use the 10COIL-GB2
Fisher's Gold Bug 2 manual describes its coils as waterproof, electrostatically shielded and co-planar elliptical, on a 7 ft (2.1 m) cable, and the Gold Bug 2 runs at 71 kHz. Fisher ships the Gold Bug 2 with a 10 inch or a 6.5 inch coil as standard, with a 14 inch coil as an accessory. The manual says to hand tighten the coil connector only and never use tools on it.
On Gold Bug 2 units built before July 2026, the 10 inch coil is the everyday prospecting size: wide enough to search open ground at a reasonable pace, yet still manageable around rocks. Where boulders stop the coil from sitting flat, the 6.5 inch coil gets closer to the target. Keep the coil low and the sweep slow when you are after small gold. Our metal detector coil guide explains how coil size and type trade coverage for separation.
