Old Surface Air Diving rig

[webetics]

I have been diving with an evinrude aquanaut for over 40 years. I just picked up a rig that said Snuba on it from the international water sports LTD. It has a float, dive flag, 10 foot hose and air regulator similar to the scuba tank hookah rigs. I can't find anything about this at all. It has no power assist and I'm trying to find out some information about it. Anyone ever see this before.
thanks,
Mark

I don't see a compressor or tank anywhere. Is there one? I hope so.

No tank or compressor, only surface air.

Wow really.I haven't tried it and I'm not a physics major but I have heard you can only snorkel about two feet deep. The pressure on the lung is to great after that to try to suck air in or exspell air. Along with c02 build up.So I don't see what good an 10 foot hose will do.Looks like a death trap to me.

It might work for going under something flat like a raft but you can't go much more than a foot deep, 2 if you're hearty. The other thing is the length of the hose. Unless that mouthpiece has in and out check valves so it's direct exhaust the dead volume of that long hose is a killer.

It actually has check valves so you can only breath in clean air and the used air is expelled through the bottom. Possibly would be useful for working on a prop of a boat or something. Just trying to find out more about this unit.

That would be about it.

Water pressure on the lungs limits depth but the one way flow will allow some lateral freedom near the surface.

I'm trying to envision what niche it could occupy that a plain old snorkel couldn't fill...

It should be surface supplied from a SCUBA tank. There was a thread on it back a few months, it's used for tourists under supervision in shallow water.

So I tried the snuba unit this weekend in Lake Ontario. 10' of hose and a mouthpiece, but no pump. I could swim on the surface just fine, but 2 to 3 feet down, nothing, not even a breath, just like physics says. Nothing ventured nothing gained!
