Nokta Simplex Ultra. NEW only used 3 times. Water proof up to 16ft. The 11" AND the 9.5" x 6"coil AND the wireless headphones are included. This package would cost you $530 brand new!!! I bought 2 and my partner can't detect anymore so I'm selling one of them. Asking $350 for a new Simplex Ultra, 2 coils and wireless headphones. It was bought last Christmas and still a 2 year warranty on it.
