The main thread on all three coils is on the Equinox Forum. 5"x10", 9"x14", and 15" round Coiltek Coils for Minelab Equinox I've been pounding the drum for three years for a 6x10 or 5x10 coil for the Equinox for nugget detecting. I was pushing for a Gold Monster style coil direct from Minelab, but no go. I was a little cautious when I heard Coiltek was doing it instead, as I imagined we would get a clone of the CTX 5x10 coil. That would be ok, but that coil was heavy and expensive.
