would the apps listed for the iphone be available on the ipod touch?

Sounds like what I did for years anyway only at 10' instead of 15'. Whats old is new again.

Yup as long a you pay for the itouch upgrade, i think i paid like $5 for the upgrade allows you to use the app store and install the Ideco Pro which is nice to have. Pick up a housing for the itouch and you can toss it in your pocket and take it diving

I did a workshop for some of our dive staff recently and one of the modules was Decompression Theory and Practice. Part of the discussion was:

Every dive is a decompression dive.

One of the staff had a hard time wrapping her mind around the concept in large part because "Decompression" meant "Staged Decompression" to him. Another participant jumped in and suggested that I say:

Every dive is an On-gassing and Off-gassing dive.

This he could understand and get -- whether we call it an "No Decompression Limit" diving, "Minimum Decompression Diving" or just "Diving" -- in every dive you do on Scuba, you on-gas and you off-gas. The key is coming up with a plan FOR YOU that works and lets you go home feeling fine.

There are any number of ways to get there -- PADI RDP, Minimum Deco, Riding Your Computer -- whatever. But just remember, you will ALWAYS need to off-gas. The real key is where you want to do it -- in the water or on the surface -- and how much where.

I did a workshop for some of our dive staff recently... Part of the discussion was: Every dive is a decompression dive.

One of the staff had a hard time wrapping her mind around the concept in large part because "Decompression" meant "Staged Decompression" to him.

I find it a bit... worrisome that dive staff (who is somehow both female and male ) struggled with that concept. What did s/he think was the purpose of dive tables/computers, and how did s/he adequately and appropriately instruct others?

Every dive is an On-gassing and Off-gassing dive.
This he could understand

Hmm... I'd go with:

What's the pressure at the surface? What's the pressure at x feet? What happens to the pressure as you ascend from x to the surface?

Marc, I sometimes "mix genders" to protect the guilty!

S/he probably does understand the reasons for the tables, computers, etc. but s/he has been so "brainwashed" with the idea of "No Decompression Limit" dives and it was hard to switch over to the idea that "Every Dive Is A Decompression Dive." To him/her, there was a bright line between "NDL" dives and "Deco" dives.

I think (I hope) that bright line has been significantly blurred!

The PADI recreational dive planner makes a 3 minute 15' safety stop "mandatory" on NDL dives below 100 feet and anytime when getting within 3 pressure groups of the NDL.

When a stop becomes mandatory should it still be called a safety stop or should it call a decompression stop or something else and if the stop is mandatory is it still an NDL dive.
Does missing a mandatory safety stop on the PADI table put a diver at greater risk than a diver skipping an optional safety stop on another table.

Opinions?

Mine is that calling it a safety stop is a bit misleading since by original definition a safety stop was recommended but optional and is optional on other tables.

Check out this article on DAN's site:
DAN Divers Alert Network

While it talks about deep stops, I think it's relevant to why safety stops are recommended or are becoming "mandatory"... Ascent rates are part of the equation.
