Minimalist Tanks

Wed Mar 22, 2017 2:53 pm

Minimalist Scuba Tanks
- One of the tanks in a Twin 38 project failed the hydrotest and left me with a single 38. I didn't have a plan for it but last Fall I cleaned it up and painted it with Galvalite zinc paint. This eventually got re-assembled with the original bushing-reducer and a nice tapered 1/2" thread USD J-Valve. But it wasn't until I returned from Sea Hunt Forever that I got the idea to make this a USD Vigo 38!
- It still needs a yellow paint job and a big round decal to be a Vigo 38 but I went ahead and dove with it at our local Sea Hunt Night. Wow, what a free feeling dive tank. Light weight and easy to don and walk around in. It was essentially neutral in the water... I wore 6 lbs of weight with and without the tank and I was neutrally buoyant regardless. Originals had K valves but mine has a J-valve.
- I'm thinking "minimalist" with this Vigo 38. I can fit an entire diving outfit including this tank into one dive bag. I can bring it along everywhere in case an opportunity to go diving comes up unexpectedly.

I think this is a cool idea. I've thought a small kit based around a pony bottle would fun to take along while kayaking. Does the harness just consist of canvas straps threaded through loops attached to tank bands?

As a kid, I remember the salty ("old guys) - probably in their late 20's using single 38's for their hull cleaning, and dropped overboard retrieval pick up jobs at the marina.

- Right now I have it set up with the 1961 plastic Bac-Pac. This is almost as compact as tank bands and harness but it does a better job of keeping the tank from rotating. The crotch strap is pretty important to keep snug for best stability.
