Which detectors the 10COILGB2-5P fits
- Fisher Gold Bug 2 built from July 2026 (5-pin coil connector)
Fisher sells the Gold Bug 2's 10 inch coil in two versions: 10COILGB2-5P with the 5-pin connector for units built from July 2026, and 10COIL-GB2 for units built before July 2026. Check the connector on your Gold Bug 2 before ordering, because the two versions do not interchange, and send us your serial number if you are unsure. 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 10COILGB2-5P
Fisher builds its Gold Bug 2 coils waterproof and electrostatically shielded, in a co-planar elliptical design, and the detector runs at 71 kHz, which sets the coil's frequency. Fisher offers the Gold Bug 2 with a 10 inch or a 6.5 inch coil as standard and a 14 inch coil as an accessory. The coil can go under water; the control housing cannot.
A newer Gold Bug 2 with the 10 inch coil fitted has a general searching size that covers ground at a steady pace. Change down to the 6.5 inch coil when rocks keep the larger coil off the ground, and up to the 14 inch coil for open, easy ground. Keep sweeps low and level whichever coil is on. Our metal detector coil guide explains how coil size and type trade coverage for separation.
