Any other divers in the house? For reference, a PADI or NAUI course is what, a week? And makes you qualified to go to 30m with an instructor? If you look at the dive tables you'll see that 20 minutes is all you get at 30m before you have too much dissolved nitrogen in your blood but that's okay 'cuz if you're doing a single-tank recreational dive you're going to use it all up in like six minutes that deep but honestly who fucking cares because nearly everything interesting - reefs, fish, recreational wrecks - are all within about 10-15m anyway so frankly that two-day intensive you take at the resort is likely plenty for your fuckin'-around-off-the-dive-boat vacation diving adventures. But that's okay 'cuz they said my safeword: "Trimix is largely outside of the scope of recreational diving practices because it requires extensive training and equipment. For a basic class, for instance, you’ll have to meet the requirement of being an experienced certified diver. In terms of equipment, trimix requires a lot." Trimix is cave-diver shit. Heliox is salvage-diver shit. Recreational divers generally live as long as anybody else, so long as they don't get too rambo on it. Commercial divers? murkier picture. I'll say this: when you substitute the air you breathe for a calculated admix of oxygen and helium, and then compress yourself to ten atmospheres, you're either aware of the stacked risk or blissfully oblivious to far too many indicators. So yeah - like Everest if instead of having to train for six months just to get to basecamp and then pay $20k and wait for permits, you just pay a dude a Benjamin and... step off the beach.It's easy to dive through the tunnel in the Blue Hole with Trimix or Heliox, but not with compressed air.
In Dahab, however, divers can buy depth. It's easy to find a guide who is willing to surreptitiously take a diver into the tunnel for €100, without asking unnecessary questions.
It doesn't take much to learn to dive. It also doesn't take much to dive. You basically need to book a trip to the Bahamas or Hawaii, spend a few days at a resort and drop like $400. From a price profile scuba is pretty much skiing. If you can afford to ski once in a while you can afford to dive, and diving is vastly less athletic.
I thought it was this one, but nay. Hopefully I can SCUBA, without sunscreen, before we destroy all the coral reefs. I dunno, I'm reassessing whether I deserve to pollute the planet by traveling around to see it.
It's also not this Blue Hole, which is where I got my open-water certification, which is hilarious, because a 50m x 50m x 45m deep pH 10 artesian aquifer halfway between Amarillo and Albuquerque isn't about to be a "world famous dive site." Everywhere worth diving requires a Farmer John at least.
Blue Hole battle initiated (this will end tastefully, for sure)
