This is a Coiltek 10x5 coil for the Minelab Equinox (800 or 600). Great for small, tight areas where larger coils cannot reach. I bought this about a year ago but only used it a few times. The Equinox is my backup machine to my 3030 otherwise it would have seen more use. Price is 150 plus 15 shipping if needed. Local pickup available.
