Its Double-D winding overlaps two D-shaped coils to reject ground mineralization and electrical interference, so it runs smooth where a concentric coil would chatter, and you cover more ground per sweep. The cost is a little weight and less separation in heavy trash, which is exactly when you would clip on the 5 or 6.5 inch instead. For even more depth on open ground, the 12 inch Double-D is the next step.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e11COIL-F75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble-D search coil, 11 in \/ 28 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFirst Texas screw-in (twist-lock) connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFisher F75, Fisher F75+, Fisher F75 LTD, Fisher F70, Teknetics Patriot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNot published by First Texas.

Use the 5 inch for trash, the 10 inch for lighter open-ground coverage, and the 12 inch for the deepest reach.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDouble-D or concentric, does it matter?\u003c\/strong\u003e This is a Double-D coil. Overlapping D-shaped windings reject ground mineralization and run smoother than a concentric coil in bad soil, which is why Fisher ships it as the F75+ standard coil.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it waterproof?\u003c\/strong\u003e First Texas search coils are submersible; keep the control housing dry.
