Twin HP 40's with USD single bar manifold

Mon Dec 29, 2014 7:24 pm

Here are a few shots of my latest creation. Thanks loads to several forum members contributed assorted parts for the project.

Karl at Scubamuseum - Indianapolis.
Bill at PSI - Texas.
Rob at The Scuba Museum - Cincinnati.
The guy at the dive show whose truck the 40's fell off the back of (good story which I will recount another time).

I took it out for a test dive yesterday and caught dinner! No bubble leaks at 3442 PSI!. Mark.

Nice! New marketing strategy....Argonaut Kraken red hoses cause lobsters to jump on your back and beg to be taken home.....:)
Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB

The balance on a short twin set is amazing. For some reason I figured it would have similar buoyancy characteristics as my steel LP 95. Turns out I had to take 10 pounds of weight off so I wouldn't do a Capt. Nemo away-mission walk along the bottom.

That looks like a lot of fun. Diving and getting lobsters at the same time.

Very cool! I'm very interested what wing, bands and harness you are using.

I have a pair of OMS LP 45's that for some time I've hoped to double-up. I believe they are 5.3" longer than yours, hopefully not too long for good buoyancy while using my double-hose regs. Each of my cylinders are about three pounds heavier than yours, but I always dive in a drysuit here and the extra weight is not a disadvantage.

18lb Oxy-Cheq wing; 5.5 in. bands from DiveGearExpress.com; and a VDH backplate with 2 in. webbing. Good luck. Mark.
