Description
When the T2's standard coil has cleared the easy depth, the 12 inch Double-D goes deeper. The 12 inch is the T2's big-coverage deep coil: the most ground per sweep and strong reach on the deepest targets, with a Double-D winding that stays stable on mineralized soil.
At a glance: This is the genuine Teknetics 12 in / 30 cm Double-D search coil for the T2 and T2 Special Edition, with the First Texas screw-in connector. It is the big-coverage deep coil, clearing the most ground per sweep and reaching the deepest targets, with a Double-D winding that runs quiet on hot ground.

Why the 12 in Double-D coil
Coil size is depth, and at 12 inches this is one of the T2's deepest and widest-covering coils. It clears more ground per sweep than the 11 inch and reaches the deep coin, the plow-zone relic and the target below the range of a smaller coil. The Double-D winding rejects ground mineralization and electrical interference, so it stays quiet on the hot soil the T2 handles so well. The cost against the smaller coils is weight and less separation in heavy trash, where the 5 inch is the better tool. When you want to work the widest open ground, the 15 inch is the coverage step beyond this one.

Frequently asked questions
Will this coil fit my detector? It fits the Teknetics T2 and T2 Special Edition, which use the First Texas screw-in connector.
How is this size different from the others? The 12 inch Double-D is a big deep-and-coverage coil. Use the 5 inch for trash, the 8 inch bi-axial for everyday balance, the 11 inch as the standard deep coil, and the 15 inch for the widest open-ground coverage.
Double-D or concentric, does it matter? This is a Double-D coil. Overlapping D-shaped windings reject ground mineralization and run smoother than a concentric coil in bad soil, which matters most on a large deep coil.
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.
