Is there ever a circumstance when someone would use an AL80 as their O2 bottle? I saw an O2 bottle marker sticker the other day - the thing was...

Ran into this on another board: You ask for 18/45. You show up at the shop, and the O2 analyzes as 18%, spot on. The helium is only 30%, though. ...

Divers A & B plan to conduct a staged cave dive. Plan called for a bottom time of approximately 120 minutes at an average depth of ~60'. All gas...

For those of you who tech dive off small boats (six or fewer divers, say), how much do you worry about the necessity to recover a disabled diver from...

I'm not talking you gotta re-build your dub regs, or add another first stage to your deco reg, or dive your wacky Dive Rite uniwing with both your...

I recently got rid of my gigantic AL13 that I had mounted to my doubles in favor of a luxfer AL6. How do you guys have it mounted to the backplate?

Does this look ok? I like the low profile but am concerned with the bends in the secondary and wing inflator hose. The first stages are SP MK16s. ...

Well I always enjoy reading writeups of other people's classes so figured I'd post about my current one that I hope to finish up next week. I have a...

I'm a photographer. I scooter. Guess that makes me a phootering scootagrapher. :rolleyes: No can do the deco cylinder on the left. I...

Lynne's thread on "Working on the Hard Stuff" has had some very good advice (and I hope y'all have noticed I've stayed away from posting there even...

Some of you may know but if not, Lynne hurt herself the other day at Alki Cove 2. She slipped and fell and in doing so fracturing her cheek; I'm...

I have one spot open for an Advanced Nitrox and Deco Procedures class taking place in the Chicago, IL area. Dates: June 10-14 Location: First 3...

A while back, Ben V had brought up Mo2vation's old Fundies class reports. Definitely a great read, and it's too bad that a lot of similar reports...

And I'm OK with that. I'm open to changing my mind, but nobody's convinced me. "Exploration." I think it has taken on a very wide and liberal...

I'm by no means the perfect diver, but it pains me to see these demonstration videos on YouTube: lkEmfkHMFXw or ...

This is specifically about staged decompression diving, rather than about technical diving in general. (Because, if you know me, you know that I...

Just wanted to let everyone know that after several months of working on this, I have finally earned my technical and cave diving instructor ratings....
