Have been thinking of dropping my money on one of these coils to run on my gpx4500 in particular the 18x15 coil but with so much marketing hype around these coils I have a hard time believing the claims these coils are more than just talk. I was hoping someone here has already dropped coin on one of these coils and can shed some light on just how good they really are from personal experience before I spend my hard earned. Here's a link to some performance claims in favor of the detech sef coils. http://www.kellycodetectors.com/excelerator/EXcelleratorMain.htm Apparently 35-55% deeper than conventional DD coils. I don't really see how they could perform better than a conventional round DD coil. What do you guys think? cheers
