This is a 12VDC single diver deck unit similar to model 130-D on the Sea Breathe website. Used maybe 3 times. Includes spare parts kit. $800.00 + shipping.
I've got one. These are great for doing zinc replacements and work under the boat. With the price of haul-outs - even left in the slings - I've paid for mine already. No affiliation with the seller, just a satisified user .
