No computers currently on the market are based on tables. There haven't been any table based computers since the early 90s. This post is a perfect example of thinking you know something about decompression theory because you know how to use a table. There is no correlation.

Retail sales in a dive shop. Medical doctor, if you also have a degree in medicine. Attorney, if you've also passed your bar exams. etc.

My answer would be, "That's correct, you don't need any more theory". (You may need a little more practical application than stated, but I believe that was a bit of humor there.) If you, like me, want more theory (I have studied well beyond just practical application), it would be no problem...

In-depth knowledge is available to any student that wants it, both through self-generated education (on the web and in books), and through formal education with advanced courses (Adv. Nitrox, trimix, deco, a wide variety of tech courses, etc.). This in-depth knowledge is not necessary for for...

Per the specs: The Worthington X7-100 is 2.5 lbs. neg. empty. The PST E-7 100 is 1.3 lbs. neg. empty. Individual tanks will vary slightly, but not much.

I'm looking forward to the oceans warming. I figure the coral will just move further north, and I won't have to drive as far to go diving. :11:

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 locally. Try on a lot of them and buy the one that...

I was wrong. I apologize.

Don't kick the reef. Don't ride the turtles. Don't eat the Timex Helix.

EDIT: Vented, posted, thought about it for a while, deleted it.

PF, I thought you were a standard mix, 32 only, men-in-black, kind of guy. (Just building my post count here; no real content; move along.)

Happy B-Day, Clay. I bought your book about a month ago, but didn't get to read it at all. I shipped it off to my sister, a new diver, in Israel for her B-Day. She's really enjoying it and says she has learned a lot from it. That makes you an Internationally Acclaimed Author!

And they call "us" clowns! Sheeesh! Tech divers, do you carry redundant fins? You're up the creek if your fins break? What's your sanity check to know if your fins are moving you at the correct speed to get you out of that overhead environment at the right time? :D Actually, I see and...

Anyone here propose teaching Ratio Deco or another seat-of-the-pants method to OW students? Anyone here propose teaching Ratio Deco or another seat-of-the-pants method to us here on the internet? Using tables is notoriously fraught with user error. Surely that is not an adequate method for a...

Very new. Released in Australia in December or January, I believe. In the USA in April, I think.

From my little bit of research, I concur with djkpsu: getting from Israel to the Southern Red Sea is tough if not impossible. I had a great time last September doing a short live-aboard trip at Tiran out of Sharm with a group from a dive center in Eilat. There is a very short report of that...

Hey, Mike, Last September I did a 3 day live-aboard trip out of Sharm with a group from a dive center in Eilat. At this link you'll find a very short report on that trip.

Yes it is. But it's not helpful at all in diving with nitrox. Read what was said a few posts ago about training vs. education.

20.44 posts per day average over 2 1/2 years. That's incredible!

For the same reasons that Decoplanner, V-Planner, Gap, your Ratio Deco, etc., don't pump out the same profile. And you know and understand that, so why ask?
