Dive Log software

[scubacub1]

Does anyone here use a computer program for logging your dives?

I have looked at a few. One of the primary features I want it to be able to input start time, finish time, S.I. time, depth, and have the computer calculate my dive profile with END of LETTER group based on NAUI tables.

I think you'll have a hard time finding that. For one, the tables are copyrighted and the software developers would need permission to use them, for another the computer profile does not always fit within the more conservative tables. That's the whole point of diving computers.

Sounds like scubacub1 was talking about a desktop/laptop type computer, while ReefHound was talking about a dive computer.

BTW, minor nit, ReefHound. AFAIK, most rec dive computers are based on models which are more conservative than those tables are based on. It's the fact that they can credit you for time spent at shallower depths that can result in longer NDLs.

Well that fact is an inescapable issue so when a table says you are a pressure group Z based on a certain accumulated bottom time and your computer lets you spend a greater amount of bottom time than that, what pressure group do you suggest the computer should show? ZA? Z++?

I said nothing about the underlying models, I said the tables are more conservative. On most profiles, your computer is going to allow more dive time than the tables. Tables are designed for square profiles and do not work well for multi-level stepped profiles much less random profiles. Trying to relate your dive computer log to a table pressure group is like trying to force a square peg into a round hole.
