Vintage Double Hose

I just purchased a "floater" aluminum tank, a tall 2475 psi cylinder, it was part of a group of steel tanks that someone wanted to sell. I looked inside for a quick visual, no neck cracks, I will hydro it tomorrow. Assuming that it passes I haven't a clue what I am going to do with it. I am pretty sure that I am not going to use it. It will probably become part of my collection of unusual and odd sized scuba cylinders.

I have two of those that need to be converted into wind chimes.... I think they are still sitting full from about 14 years ago.....

Is it one of the early USD or the really tall DACOR?

It is really tall and has Dacor stamped on it.

Those cylinders should have had this sticker on them.

Oh, boy....it passed visual and hydro. I am now the proud owner of a tall, low pressure aluminum 72....that I will probably never use.....I know, I will loan it to house guests that are annoying.

Use it with a DACOR Nautilus for the ultimate in buoyancy

Get another one like it and make a small pontoon boat.

I have two of the old girls (US Divers), set up as doubles. Brought them up to Portage this year and dove them. Floaty as can be (6 - 8 pounds positive each). Threw my trim all to hell. Because I didn't have tank weights on them, I added about 14 pounds of lead to my weight belt and suffered the indignity of feeling like someone was grasping me by the backside and lifting while weighing me down with the extra lead round my torso. Also the length of the tanks make them uncomfortable when placed low on the back for a dh regulator.

More a curiosity piece than anything else.

Sorry I missed that George

Perhaps it is better (for my dignity at least) that no video record exists of that dive. I may be buying some tank weights in the future to make these gals somewhat more diveable; otherwise, they make great conversation pieces.

I too fought those danged floaters when they first came out, and finally poured some round disks of lead, the same diameter as the cylinder. They fit between the tank boot and the bottom of the tank. I don't remember the weight, but it seems like they were only about 1/4" to 3/8" thick. You can determine your weight preference and then pour your own to suit.

One downside we discovered was that the rubber boots of the time could sometimes slip off the tank, but a big hose clamp around the boot will take care of that. The modern self-draining plastic boots may fit tighter, but can be done the same way if needed.

I have a couple of aluminium tanks in the UK.

Not sure about in the USA but we have to have our tanks (steel or aluminium) tested every 2.5 years including the valve (visual test at 2.5yrs and hydraulic at 5yrs).

Also with aluminium tanks we have the added cost of a "Visual Eddy" test.
