    Nemrod Snark III OPV Assembly

    The original OEM Nemrod Snark service manual exploded views of the OPV are very low resolution and a bit hard to see. Here's an updated version!

    I'm now turning my attention to the Nemrod Snark LP diaphragm... Scuba Museum has recreated the exhaust valve in food grade silicone rubber: Scuba Museum Nemrod Exhaust Valve The original LP diaphragms were moulded from neoprene rubber, and are often found totally disintegrated on older...

    Nemrod Snark III Double Hose LP seat assembly?

    Continuing my Nemrod Snark DH reproduction parts, I'm now looking at the LP seats... These are co-moulded around a metal shaft and X shaped stabiliser ribs, and I need to understand what this substructure looks like to create accurate RFQ drawings for the metal and co-moulded rubber parts. Food...

    Heinke Merlin DH reg info?

    Morning vintage team… I have just been given a Heinke Merlin DH reg from a former marine biologist now retired and downsizing his household. He used to use it as his primary regulator back in the day so I’d like to restore it back to working order. Trouble is while I’ve successfully restored a...

    Poseidon Jetstream servo valve repair

    Clearly I need to get out more… Here’s my procedure for overhauling a Jetstream servo or pilot valve that may be dribbling some gas… easily checked using my service test collar (shameless plug).

    Nemrod Snark III Double Hose LP port adaptor?

    Just canvassing expressions of interest if I get a run of Nemrod Snark III DH LP adaptors made up? Later model Snarks replaced the iconic 'coin slot' LP Chamber Plug #2994 with #10769 LP Port adaptor which allows the usual LP SAE-3 3/8-24 UNF hose fittings to attach. Price will depend on...

    WWII Plane wreck dive sites in the Pacific?

    Just wondering where the best dive sites are to see WWII plane wrecks? Having dived on a few now in PNG, I've found I enjoy plane wrecks more than shipwrecks! Solomon Islands springs to mind at first... any resort or LOB recommendations? Other sites close to Australia?

    For Sale Poseidon Jetstream XStream second stage service tool 2894A

    I designed this as a successor to the 2894 OEM service tool (which was essentially just a cut down Jetstream body) long discontinued by Poseidon. It enables a LP valve housing assembly to be easily pressurised and checked for leaks in a water bath outside the regulator body. When using a cut...

    Atomic Comfort Swivel hose onto a Poseidon XStream or Jetstream...

    I've long been a fan of the 'elegant simplicity' of the Atomic Aquatics Comfort Swivel hose, and have a couple on my Atomic (OEM) as well as Sea Hornet Command Air regs (Universal). Seems not all on SB agree with me, but its a personal preference for having easy 360 deg rotation without having...

    Source for plastic SAE -3 and -4 LP HP port plugs?

    Just wondering if anyone has a source for those plastic threaded port plugs that fit LP SAE-3 and HP SAE-4 ORB ports? Very handy to plug spare first stage regs and much easier to remove/replace than the usual unthreaded tapered plastic plugs, and actual port plugs are not required in storage...
