Description
When you are covering a big gold patch or chasing the deep nugget, the biggest coil reaches furthest. The 11 inch Double-D is the Gold Bug's coverage-and-depth coil: the most ground per sweep and the deepest reach, with a Double-D winding that holds steady on hot, mineralized goldfield ground.
At a glance: This is the genuine Fisher 11 in / 28 cm Double-D search coil with the First Texas screw-in connector, for the Gold Bug, Gold Bug Pro and Gold Bug DP and the wider Fisher and Teknetics screw-in family. It is the coverage-and-depth coil: the widest sweep and the deepest reach for working large gold patches and open coin ground.

Which detectors does it fit?
This coil uses the First Texas screw-in connector that the Fisher F-series and the Gold Bug, Gold Bug Pro and Gold Bug DP share. It does not fit the Gold Bug 2, which has its own dedicated connector, or the plug-in Teknetics EuroTek and Digitek. This coil is compatible with: Fisher Gold Bug, Fisher Gold Bug Pro, Fisher Gold Bug DP, Fisher F11, Fisher F19, Fisher F22, Fisher F44, Fisher F5, Teknetics Alpha 2000, Teknetics Delta 4000, Teknetics Gamma 6000, Teknetics Omega 8500, Teknetics G2+, Teknetics EuroTek Pro.
Because it shares the First Texas screw-in connector, this coil also fits the Fisher F-series and Teknetics screw-in machines listed above. It does not fit the Gold Bug 2, which uses its own dedicated connector.
Why the 11 in Double-D coil
When the ground is open and you want to cover it fast, or the nugget is deep, the 11 inch Double-D is the Gold Bug's answer. It sweeps the widest line of the Gold Bug coils and reaches the deepest, and its Double-D winding rejects ground mineralization so it stays usable on the hot soil and hot rocks of real gold country. The trade-off against the small coil is sensitivity to the very smallest gold and separation in heavy trash, so many prospectors carry both and switch by ground. Drop to the 5 inch for tiny gold and tight, trashy spots.

Frequently asked questions
Will this coil fit my detector? This coil uses the First Texas screw-in connector that the Fisher F-series and the Gold Bug, Gold Bug Pro and Gold Bug DP share. It does not fit the Gold Bug 2, which has its own dedicated connector, or the plug-in Teknetics EuroTek and Digitek.
How is this size different from the others? The 11 inch DD is the maximum coverage-and-depth gold coil. Use the 5 inch for tiny gold and trash, and the 10 inch DD for an everyday balance.
Can this coil help me find gold? Yes. This coil fits the Fisher Gold Bug (19 kHz) gold machine and is the largest of the Gold Bug coils, for covering ground and reaching deep nuggets. Any detector finds gold jewelry; for nuggets, the Gold Bug plus a Double-D coil is proven. For the smallest gold at higher frequency, Fisher's Gold Bug 2 runs at 71 kHz.
Is it waterproof? First Texas search coils are submersible; keep the control housing dry. For a verified depth rating on your exact machine, call us and we will confirm before you hunt water.
History Seekers is a small American business and an authorized First Texas dealer (Fisher, Teknetics and Bounty Hunter are one El Paso company). Everyone here detects, top down, for coins, relics, jewelry and gold, and prior field experience is a hiring requirement, not a coincidence. The person who answers your fitment question may be the one who packs the coil and drives it to the UPS drop. The story is more important than the artifact.
