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...
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...
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...
NEW design Poseidon Jetstream XStream second stage to Atomic Aquatics Comfort Swivel adaptor
This specialist adaptor allows a Poseidon Jetstream or XStream second stage regulator to be connected to the 'elegantly simple' Atomic Comfort Swivel hose.
While both the Jetstream and XStream...
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).
Often there are white crusty deposits on the tiny seat face that will have built up over time mainly...
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...
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?
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...
An image of US Navy divers recovering debris of the downed Chinese surveillance balloon came up recently... one thing caught my eye, they are using debadged Poseidon XStream regulators!
So there you go...
Been following up some PNG dive operators for a potential return trip in 2023...
Sadly it seems MV Chertan is no longer operating, the vessel has been listed for sale and the website is no longer active.... FYI

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...
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...
Quick 5 minute 'overview' video on diving New Britain PNG primarily from Walindi Resort and aboard MV Febrina.
I plan on uploading a longer version incorporating footage from Kavieng when I get time.

I was using the Kraken DH when...
I've got a vintage Poseidon Cyklon 300 reg that needs a new LP hose.
These originally had a G1/8" port that sealed with a plastic washer vs an o-ring, the LP hose had a non-standard M14x1.25mm connector to the all-metal second stage.
The original hoses are rigid and cracked but the connectors...
Quick heads-up to Australian divers and any foreign visitors to Melbourne... OZTek is back!

Currently chasing Poseidon Cyklon, Jetstream or XStream first and second stage service tools.
I've stripped down and cleaned my metal bodied Cyklon and its in surprisingly good condition, certainly worth rebuilding...
Also a LP hose to suit an early Cyklon 300 (without integral OP valve) if...
Part 1: Getting there is half the fun…
Travel to PNG is generally fairly straightforward, with daily flights from Cairns in Australia and regular Air Niugini direct flights from Brisbane and Singapore however things change radically the moment you leave Port Moresby Jacksons International...
