Somewhere in the bottom of that pile are 2 K bottles of Helium, 2 K bottles of O2, 2 sets of doubles, and a few more stages.

I was my first dive in Chan Hol. We T left, T left. I noticed a lot of side passages that I'd like to check out!

I like the frantic pointing of "OMG, it's a seal!" :)

Thanks! The pottery was just inside the cave at Chan Hol. :)

I spent a week in Tulum in early November. Here's a video from a couple dives. http://www.youtube.com/watch?feature=player_embedded&v=UeMVhvcHZEY

I've only been down to 100ft in Blue Abyss. I was basing the 240 foot comment based upon the cave map. I do know that is current exploration in the Blue Abyss and The Pit that has pushed the line in both caves recently. It's my understanding that Blue Abyss is now 100m deep past a no mount...

The Blue Abyss is 240 feet before the TKM restriction, I believe. But that wouldn't be the best training ground for advanced trimix, as it is a 40 - 60 minute swim just to get to the Blue Abyss, depending on which line you take. Beyond the swim, that would be a lot of logistics to stage the...

Very nice video! The upstream and downstream tunnels are a couple of my favorite dives!

That sucks! I've lived in the area for a few months and have only had a bicycle stolen so far. Knock on wood, that'll be the only thing! If I come across anything, I'll let you know.

I'm moved in and mostly settled. Start the new job Monday. My hours will be weird, but I'm looking forward to getting some dives in soon!

Thanks! I'll do that!

I am going to miss Santa Rosa actually! Diving at Rock Lake pretty much monthly has been a treat and I have some awesome friends in the NM and CO areas. I'm moving because of a job and I'm looking forward to it. :)

Howdy! After many years in the high plains of the Texas Panhandle, I'll be moving to San Antonio in the next few weeks and I'll be looking for dive buddies. :)

No matter how many times I read it, all I see is that you don't believe in self rescue in technical environments as that's what your words say. I believe what you're really referring to was you don't believe that diving in restrictive areas where your team is slow to respond or unable to...

Not necessarily. The necklace is tied into the distribution block, thus going to the necklace gives you gas from the same gas source. But again, on a downstream designed second stage, you're generally going to either be out of gas or be in a valve roll off scenario if the second stage stops...

So, in a gas loss situation (with backmount doubles, deco/stage, or an inflation system) you don't do ANYTHING except let your team mates fix the problem for you? In a maskless situation, you don't attempt to deploy a backup or attempt to signal team mates? In a run away inflator scenario, you...

Of course, and I've been agreeing all along that I don't think that the z system is the best solution for being in a tiny hole.

I don't know about your cave class, but in ours, we were required to exit at the same speed or faster that we went in while sharing gas in a zero-vis scenario. If you're taking twice as long, then something is very wrong.

Bubbling doesn't automatically mean a failed regulator. You don't automatically swap second stages on manifolded doubles. In manifolded doubles, if you hear bubbling behind your head, your first quick move is to determine which side is bubbling and shut down that side. If you are unable to...
