Description
The most useful coil is often the one that just works everywhere, and does not weigh you down. The 7 inch concentric is the light everyday coil for the F11/F22/F44: enough coverage and depth for general hunting, little enough weight to swing all afternoon.
At a glance: This is the genuine Fisher 7 in / 18 cm concentric search coil with the First Texas screw-in connector, for the F11, F22 and F44. It is the light, balanced everyday coil: more reach than the 4 inch, easier to swing than the big coils, and a clean concentric response for confident pinpointing.

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 F11, Fisher F22, Fisher F44, Fisher F5.
Why the 7 in concentric coil
A 7 inch concentric coil sits right in the sweet spot for general detecting. It covers more ground and reaches deeper than the little 4 inch, yet it is light and maneuverable enough for long hunts and moderate trash. The concentric winding gives a symmetrical detection cone that many hunters find easy to pinpoint under. On the F11, F22 and F44 it is the coil you leave on for most of your hunting, dropping to the 4 inch only in heavy trash and stepping up to the 9 or 11 inch when you need to cover open ground or chase depth.

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 7 inch is the light everyday coil. Use the 4 inch for heavy trash and tight spots, the 9 or 11 inch concentric for more coverage, and the 11 inch DD for depth in mineralized ground.
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.
