Description
On open ground, the coil that covers the most acreage per sweep finds the most targets. The 11 inch concentric teardrop is the coverage coil for the F11/F22/F44: the widest concentric sweep in the line, for clearing fields and parks fast without giving up pinpoint precision.
At a glance: This is the genuine Fisher 11 in / 28 cm concentric teardrop search coil with the First Texas screw-in connector, for the F11, F22 and F44. The largest concentric coil offered, it sweeps a wide line for fast coverage on open ground while keeping the clean, symmetrical response that makes concentric coils easy to pinpoint under.

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 11 in concentric teardrop coil
When the site is open and the finds are scattered, coverage wins, and the 11 inch teardrop clears the most ground per sweep of any concentric coil in the line. Its concentric winding holds a symmetrical detection cone for confident depth and pinpointing in mild to moderate soil, so you cover fast without losing target ID. On the F11, F22 and F44 it is the go-to for fields, pastures and large parks. In hot, mineralized ground the 11 inch DD stays quieter; in heavy trash, drop to the 4 inch for separation.

How is this size different from the others? The 11 inch teardrop is the widest concentric coverage coil. Use the 4 inch for trash, the 7 inch as a light everyday coil, the 9 inch teardrop for a lighter coverage option, 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.
