Gone for diving

Got mine from tsc. It's more of a farm/ implement tube.
You need one with a small inside diameter. And still big enough to orally inflate. With a powerinflater it's the ultimate bungee wing. I have run it without a dump valve no problems.
Other than once I overinflated and the bulkhead hole was oversized, and it stretched the rubber and the bulkhead came out. So any holes you put in the rubber make them quite abit smaller then you need.
