In the interest of safety, I beleive that I should be able to read any common dive table out there, so I purchased the new RGBM-based NAUI (rec) table. Speaking of simplified!
Three columns, one each for dives one through three for the day. Pick your first dive in column one by depth, read across for the next two dives.
Interesting restrictions:
* Minimum SIT of 1 hour (makes tables simple)
* Maximum decent rate of 75 fpm
* Maximum ascent rate of 30 fpm
* "Safety stop" at 15 fsw +/- 3 fsw for 3 min REQUIRED
There is no mention of the phrase "No-Decompression Limit," using "Maximum Dive Time" instead -- an improvement in terminology, IMHO.
So much for "knowledge of the tables" meaning a lot.
Has the world gotten too simple? If NAUI adopts these tables as "standard," how will their divers deal with dive boats that have a typical 45-minute SIT? Will they just trust the boat's DM? What if such a diver leaves their tables at home and only has the USN-style tables available?
:reaper: Woo hoo! 10 min MDT at 130' -- and it says I only need a 9 min at 15 fsw deco stop if I extend by 5-10 min. 20 min at 130' on air -- LET'S GO!!
(In defense of the tables, the deco stops are general across all depths. The illustration is one of extreme stupidity by such a diver, but I'm sure you know one that....)
Could this be the first step to moving to computers for another agency? Some PADI instructors I have talked with think that PADI's placement of tables and instructions into a sleeve in the back of the book (instead of within the text) is a step in preparing for that direction.
(mods -- feel free to move if in wrong forum)
