World Record: Dave Mullins (NZ) 265 meter dynamic apnea

Interesting stroke, very slow. I was wondering when he started to feel the need to breath. Then after 200m he visibly accelerated his stroke so that answered my question. Anyone know what kind of monofin that is? Looks like fiberglass.

So rad! Way to go, Dave!

Dave uses a Hyperfin, but I can't remember from which manufacturer. And yes, it's fiberglass.
