Unidentified dive gear, what is this?

[Ted55]

I just put it in water. It's slightly buoyant. I also made a greater effort to remove the foam, I couldn't. It may be glued on.

Maybe it's a "lifestyle" thing?

It’s a takeroff. Works in the opposite of a leaveron.

Problem solved

Nothing, seems to be solid. I know where you were going with that though. In Cuba I dove with a dive master who had BB's in an aluminum cigar tube. When shaken, it was great attention getter.

If it seems solid it's because the banger is frozen in it. It's definitely an attention getting shaker. Shake it harder. Never mind the neighbors driving by while you are in the garage furiously shaking your yellow thing. Nothing to see here, move along. Smile weakly.

Wookie wins! Mystery solved. After repeatedly banging it on my tile floor I was able to get something inside to move. Still not sliding freely, but I think it is noise maker. Thanks everyone.

I'd like to see more divers with a tank banger with a soft foam covering to prevent it from making any noise

Well, if it wasn't a noisemaker before it is now!

And what am I, chopped liver ??
"...but are you pretty sure the inner part isn't hollow? If so, it might possibly be one of those attention-getting rattles, with the inner ball stuck somehwhere inside."

Yeah, but I made him go make it work.

Maybe it floats just over the diver as a diver/pair/group id float:
Diver: "Jim in red, sally is blue, tom is green"
Pair: "Why are none of the buddy teams together??"
Group: "If you are a blue diver, and you find yourself surrounded by red divers, this is not your group."
