His contributions to our safety will live on for many moons.

Sundial. :)

My statement is based on: http://www.diversalertnetwork.org/news/article.asp?newsid=514 "What is interesting, and not necessarily intuitive, is that an in-water stop with a relatively rapid ascent rate appears to be more effective at eliminating inert gas than a very slow ascent rate. As can...

:D!!!

From another lively thread that wasn't generally about this topic: Information on the 'latest' best ascent profile? Why, right here, Stan. (First, I always like to remind you that I don't know what I'm talking about. Really. I'm not an expert. I'm not even very experienced. I have only...

Thanks for the link. Looks like there may be some interesting articles there. I'll read up.

(Clearly, I'm much less of an expert than you.) I agree with your first paragraph completely. A few DIR-F students here have mentioned having been taught a 30 second travel - 30 second stop (very slow) linear ascent profile on rec no-deco dives. That is a different "DIR model" than the "DIR...

(I know this doesn't really add anything of substance to this discussion, but...) Sounds kinda like a dive computer to me.

That means you could empty a 12L tank filled to 1 bar in less than a minute. Cool. :D

Oh, bah. What does he know? He can't even get his mask de-fogged!

Great. Then we'll have SAC, SCR, RMV, and now BR. Another (semi-)synonymous term to deal with.

Lynne, you are certainly on my top 5 QUALITY SB Posters list! Pretty darn good for a yearling! Mazel Tov!

Perfect answer, Capt Gary. I'll remember that next time I'm headed down to the Keys.

I've done this one before, so I'll repeat myself: My opinions, and most people disagree with me: 1st priority: exposure suit. It's personal equipment. It's all over your skin. It's like underwear, and I won't wear other people's underwear. Also, like a mask, fit is everything. Buy it...

So, where have Uncle Pug and his valve been lately? I know he took a moratorium from the board, but maybe it's time for a return.

Especially fairybasslet, eh, Frank?

From this DAN publication (worthwhile reading): "In spite of gradual reductions in bottom time over the past decades, ascent rate and the addition of an arbitrary shallow safety stop at 5 m (15 ft) for 3-5 minutes, neurological decompression sickness remains a significant problem in...

First BC, a used ScubaPro came with a patch. Replaced one bladder in an old Zeagle BC. One welded seam blew in a Halcyon bladder-less wing. Replacement came with pinholes. Recently punctured the third Halcyon through both front and back bladder-less layers. That's all in about 350 dives. I...

Dive Jupiter. BTW, It may be too early in the season for the Manatees.

Not an answer to your question, but a bit of advice: Are you wearing a hood? Nothing will help keep you warmer than a hood!
