Have to see it to believe it!

I shot this while on vacation in Cozumel in 2005. David is a DM with Dive With Martin.
I thought everyone here would enjoy it. :14:

Air ring swim thru brought to you by TheAquaPlanet.com

That looked pretty damn cool!

Looks great but isn't he holding his breath all the way up?

Probably not much breath to hold after blowing the ring

True, but highest rate of expansion is in the shallowest water, and the amount of air needed for a ring is not that much. Air compresses to 1/2 in 33 ft of water. Wouldn't take more than 1/2 lung full to overexpand. Looks like he starts in about 30ft or less.

Still impressive.

Yes, we were at 32 feet.
Back on the boat, David told me had only been doing it for a couple of months. I will see him the week of 4/4-4/11 and ask him if he still does the famous "air ring swim thru".
