Other: to satisfy a legal requirement, as in cozumel.

DCS is far down in my worry list while diving, even when doing deepish longish stage deco dives. But Matt's post seems more of a "here's a general flow of conversation" type of deal than specifically suggesting being supervised to mitigate DCS risk. My .02? If you aren't comfortable diving...

Too bad. When PAC star was is king harbor it was my favorite op (being minutes from my house helps). Never had any issues regarding cancellation refunds. Sorry to hear that.

So your go ahead plan is to learn the dubs in a wetsuit? If so, keep in mind the weight of those things. Steel plate, bands, valves, manifold (I assume) and two steel 130s. If you have a catastrophic wing failure, can you make it to the surface? You could ditch your gear, but with any...

3) Only way to know is to do a weight check. Runs search for how to do so. Note that you are compensating for twice as much gas weight as with singles 4) it could be a lot of things. Your suit could be too tight, your undergarments could be too tight, the plate could be too low, etc. You kinda...

Have you been diving doubles before or are you adding both a new configuration and a new suit at the same time? 1) I use a bungee to keep the inflator hose in check, but aside from my initial descent dump almost exclusively from the butt dump. I'm generally prone, and the hose is less...

I personally prefer to switch sooner (50% at 70) - helps mitigate how much reserve gas i need to carry. It's a solid 120' dive (average depth).

I've never experienced anything I'd call "feeling" narcosis. I have recognized its affects, though. Generally, my memory/attention goes to hell (look at my gauge and immediately have to look again type of stuff), and sometimes I get nervous. I attribute this to narcosis because reducing depth...

There's no good or bad, there's what you breathe (i.e. need). I need less gas than some of my friends, but put me in the water with someone like Ligersandtions and I'll probably go through 30% more gas than she does. That's not bad, that's just the way it is. The closest you'll come to good or...

It's good to see that nothing's changed in my (more-or-less) hiatus from scubaboard. Oy. To paraphrase NWGratefulDiver's oft description of some DIR folks, I'm going back to be the best I can be at something else now (in particular: parenting).

You're shooting Hogan too, right? It's even worth being blinded by 70 watts of mercury gas arcs (or whatever...)

Just watched this again. So good.

One more comment. It's not that it will supposedly be 2. There are two factors involved in that number. One: twice as many people are now breathing from it, and Two: perhaps your individual consumption rate will increase due to stress. Assuming you each have an average sac rate of .8, holding...

You aren't consuming gas at 1+85/33 ATM throughout the entire ascent. At the inception you're at 85. A minute later you're at 57. A minute after that you're at 28, and a minute after that 0. *If you truly hold a constant ascent rate* the average pressure at which your regulator will deliver...

You're heavy on reserve, but that's not a bad thing. For your 3 minute ascent from 85 you've computed 3 minutes AT 85 (should be at 43 for a constant ascent rate, i.e. halve that segment's requirement).

You can breathe off a cylinder at a known depth (eg 0) watching an SPG for a known amount of time and do some minor math to come up with a value for PSI/min/atmosphere. If you always use that (type of) cylinder, there may be no practical reason to do the further math of computing the...
