Personally, I think what Doug did was wonderful. I just went along for the ride.

dsteding and I did it simply. He offered an item here. I PayPal'ed the fund the amount he asked for it (plus a just little more). He's sending the item. Simple.

1. I've only used a Pelagic (Aeris, Oceanic, Sherwood, others?) computer a couple of times many years ago, so I'm talking out my butt here, but from reputation (reviews in magazines and Scubaboard) I wouldn't suggest you go with a Pelagic unit if you do any deco based on your computer. Their...

I'll mark the mask with a "TDG".

Age is considered a predisposition to DCS. Nitrox reduces your nitrogen loading when compared to air, assuming the same time and depth exposure. The advantage of nitrox is not more oxygen, it's less nitrogen. Anything oldies can do to reduce nitrogen load is considered good: nitrox...

1. I am not a doctor and I don't know squat. 2. I agree with Charlie; Call DAN. 3. It's Immersion Induced Pulmonary Oedema.

Yep. Known bug. I was corresponding with Cressi-USA about it for a few months from September 05 - March 06 with the assistance of my LDS. They took back 2 of them from me for analysis, replacing them very promptly. The programmers in Japan determined that it was a stack overflow in the...

Splashdown or Starfish in Boynton. Jupiter Dive Charters (Temptation) in Jupiter.

I like the reefs better in Boynton. YMMV. Splashdown or Starfish for Boynton.

A day in Boynton Beach and a day in Jupiter (just below and above West Palm Beach, respectively) will be worth your while to plan on for good drifting. They're on the route to the Keys. Each spring really is different, each their own personality. They don't hold my interest like the ocean...

We'll see about that when they dump the water out of Lake Okeechobee down the canals added to all the runoff. We do need the rain though.

Boynton was like that yesterday, too. 81 degrees, drift 25 feet, 73 degrees, drift 25 feet, 81 degrees... We were heat seekers, like missiles.

You didn't happen to find my virginity there, did you?

Always do what the seat-of-your-pants is telling you. (oh, and make sure to sip the cool-aid. twice) ;)

You're right, LS. "Table models" is your sloppy term. It borders on outrageous ignorant bs. See how I twisted what you said into something you didn't say? Kinda like you've twisted something I said into "computers don't use this kind of math and algorithms".

Good answer to the original question. But I disagree. Learning to use tables is difficult for many (most?) OW students. That is why so much classroom time is spent on them. I'm not familiar with how to use the new NAUI tables. They may be much easier. I'll check 'em out as soon as I can...

What are "table models"? What was "outrageous bs.!!"? I've read of mechanistic models, empirical (probabilistic) models, and (most widely used) mathematical models. I've never read of "table models". Results of these models may be only lists (tables) in the case of empirical models, or they...

And I know HOW to use a slide rule. Do you? They stopped teaching that tool a while ago. Has that hurt your ability to function? I think not. There is that same 'understanding' myth again. When you learned arithmetic did you learn flip-flop logic? Did they teach you binary arithmetic? Do you...

Yes, they did. And I agree, teach arithmetic first. But I see nothing in OW class that equates to learning arithmetic. I see tables as the same as learning log tables, slide rules, even an abacus. I suggest demonstrating them to the student, and if they want to know more about them send...

Quote from Deeper Into Diving, Lippmann and Mitchell, October 2005: "In any event, the use of any decompression tables by recreational divers is diminishing, rapidly being replaced by dive computers. Divers Alert Network (DAN) Project Dive Exploration data from 1998 to 2002 indicated that...
