I have a bh platinum with the 8" concentric coil. I have not used it a lot but it is the same as a gamma 6000 from teknetics i think. Its recovery speed is very fas, the depth seems to be the same as my omega 8000. Also the coils from my land ranger pro interchange with it and the 5" f5 coil really makes it fun to use. What i was wondering is i have not seen very many people talking about it. What do all of you out there think about this detector?
