Its detection field is small and sharply focused, so in iron-infested homesites, old foundations and dense-trash parks it isolates a single good target where a stock coil reads a coin and a nail as one signal. It also reaches the tight places finds hide: fence corners, between roots, along foundations. What it gives up is coverage and depth on open ground, so most hunters keep it as the trash-and-tight-spaces coil alongside a larger all-rounder.\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\u003e4COIL-FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003econcentric search coil, 4 in \/ 10 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 F11, Fisher F22, Fisher F44, Fisher F5, Teknetics Alpha 2000, Teknetics Delta 4000, Teknetics Gamma 6000, Teknetics Omega 8500, Teknetics EuroTek Pro\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.
