Do you dread the table portion of classes?

What if on the second day of dive in your week long vacation at Truk Lagoon, you've found out that you had left your iPhone's recharger at home and none of the people on the boat has a compatible recharger?

What will you do?

Easy. I pull my plastic RDP from its slot in my log book and compute my pressure group, like I do for practice on every dive. The reason I love my iPhone version of the RDP is that I almost always have my iPhone with me but usually only have my RDP with me when I'm diving.

Man, you're taking the fun out of my hyperboles.

Yet I don't know a SINGLE (not one!) DIR diver who uses that table. I certainly don't, nor do any of my buddies. Neither GUE nor UTD teaches that table. Far, far easier tools available.

Nevertheless as tables go the format is great.

R..

That's what I thought too. We'll see. I'm doing the PADI course. They teach the calcs too. It's not difficult stuff, but then again I've never strayed far from math in my daily life. I can understand how someone that has not picked up a math book in a few years could have some trouble with the calcs.

Should have looked into the e-learning...

If you can read the basic dive table, you can read the Nitrox dive tables. They work exactly the same. One is for 32% and one is for 36%. The other table just converts your minutes for you based on what O2 level you are using so you can use the basic dive table to do Nitrox calculations.

But if you learn the basic table well, the one for compressed air, you should have zero difficulty with the Nitrox tables.

The key to learning these is to just find as many examples as you can and then do as many problems as you can. There is a flow to them that after awhile becomes almost automatic.

I'm worried about me being able to pick it up. I've got the tables down 100% - never been an issue. I always seem to get put in class with unprepared divers. That's what I'm griping about.

Aha. I get your point now that I re-read your original post. I agree. The Nitrox class should take about 30 minutes to understand the tables if the people in the class indeed "got" the basic dive tables the first time around.

Students must realise that learning the tables are as important, if not more important, than many of the skills they learn in an Open Water Course. Managing your nitrogen load is what keeps you from getting bent, thus however long it takes you to understand them..... get it in!!!

A good instructor (with average students) should be able to teach the tables in about 30 minutes. Nitrox is even easier because the student has already learned how to use a basic (in the case of PADI) air-based RDP.

Your instructor should explain how the back side (the RNT/ANDL side) works by reinforcing that it tracks the N2 exposure the same way no matter how may repetitive dives you do. Any other instructors out there agree???

Best of luck with your training!
