Used (under 30 dives) Scubapro ® 200 bar (3000 psi) DIN Isolator manifold with Sherwood rubber knobs and inserts. Oxygen cleaned. Has 3000 psi burst disk installed (easily replaced if you must). There is nothing wrong with this manifold, other than I replaced it with Halcyon (yeah, I know, whatever, get over it). I was going to set up another set of doubles with this manifold but school got in the way and X-mas is at the door, so this pristine manifold can be yours for the wee bit of $110 plus shipping (shipping weight is 6 lbs) and insurance (optional, but I would take it…after all it is only $3.20). The best deal is Priority Mail (believe it or not, it’s only a 70 cent difference between that and Parcel Post) for $15.95 within the contiguous 48 states. I will consider delivery to cave country, I will be there for Thanksgiving. So if you’re really interested send me an e-mail. I can e-mail you pictures of actual manifold (still having trouble with linking the image to this message but you can see it under images look for Scubapro 200 bar manifold. Thanks for looking and dive safe. cevesque@nefcom.net
