Vintage U.S. Divers Co Conshelf XII.
4000psi Service.
Pretty darn rare to find one new in the box.
I’ve had this thing for a ridiculously long time and never needed it. When I do get back in the water I have my trusty old XIV and my R109.
Sure, you can find them used, but if you really want to own a new one, and don’t have a Time Machine, here it is.
Box weighs in at about 5lbs. USPS Priority Shipping.
Thanks for looking, and or bidding.
Ps. It’s going to need a new more flexible mouthpiece and hose I would image. The serial number starts with a 75. If that’s the year…professional servicing is on order of course.
