I have used Detech coils and still do, I also use Nuggetfinder coils...I have used coiltek but found them a bit to touch sensitive working around rocks and bushes. My most successful coil in Detech is the Elliptical 15x10 Mono.... I have used the Nuggetfinder Evo coils, and prefer the 12" round over the larger ones. The Evo and I am sure the Elite coils are the same, super hot and react to hot spots, you will dig more ground noise or what appears to be real soft deep targets...reducing gain helps. Reality is.....all the major brands are good coils...I have no allegiance to any of them, as long as they squeeze out gold for me I keep them. Detech makes a good coil, built well, and run stable, and are not bump sensitive. Over the years, all others now have a slight sensitivity to bumping into rocks and such...the Detech not. Don't get to hung up on which brand..just decide on one and buy it....they will all find you gold if you get the coil over a nugget. Good luck........and Happy Hunting.
