I was watching a show called Wild Pacific this morning, and these guy's dive plan was to dive to 190' to collect a sample of coral from that depth. Then they giant strided off the boat with what looked like a single AL80 strapped on. No Nitrox, extra bottles or other gases evident. Then they descended to "190 ft".
They collected the sample and the narrator said they "hurried back up" to give the researcher the sample they'd collected. They didn't show any stage bottles or decompression stops. They just showed them getting back on the boat.
Now, I'm no deep diver. Deepest I've ever been was to about 90 ft in Cozumel.
Is it even possible to go down to 190 ft and return to the surface with just one bottle of air, let alone spend 10 minutes down there hammering a piece of coral loose?
Second of all, will coral even grow at 190 ft?
