Detech 15 x 8 Mono Coil Test/review

I got a Detech 15x8 for my gpx4000 couple months back, got to use it quite a bit in Nevada in June on a six day trip, I am now using that 15x8 as my go to coil for most hunting due to how well it works for its size, no gold yet but its pulling tiny metal out of previous minelab dig holes left by others, its just what Kon said, sensitive as a smaller coil yet goes deeper than a larger coil. I am headed back to Nevada for a weeks detecting last part of August, to an area well known for small gold as well as multi oz nuggets, I am confident I will find the goods this next trip with the 15x8. I have pared down my gpx coils to a 8" round mono commander coil, the Detech 15x8 mono, and a Coiltek 14" Elite mono.
