2 complete OMS Modular DIN h-valves. NEW! Left and right post, plus h valves for each post, plus yoke adapter inserts, plus end caps (if you want to just use as a K-valve. Great for full redundency; better than a "pony bottle". Just use the H and a larger tank; then dive the "rule of thirds". Perfect for doubles divers who want to use their regs on a single tank setup. And if you are thinking of heading towards doubles diving, then just add the OMS crossover. For sale on EBAY; look for auctions by JHC2 or go to http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1827636204
