Of course on really shallow dives, like 30 feet I pretty much use neither tables or computer, mostly just watch my air and use a dive watch. On deep dives I use both tables and computer (watch as backup). I use the tables to plan a square profile--most of my deep dives are in fact pretty square, as I collect shells, and they are on the bottom- haven't done many dives that are really multi-level. I use the computer to compare my actual dive remaining bottom time to that of the squre profile.
Do You know we added the EDGE to the our simulator?
Karl Huggins (that wrote the code for the EDGE) said we did it almost right
Alberto (aka eDiver)
I'm sort of a combination of 1 and 2, I use a computer, but generally only as a dive timer. It helps that our tables are designed for multi-level dive planning
All of the above!
It very much depends on the dive. On most shallow water recreational dive I "plan" the dive by using the dive planning mode on my wrist computer to check NDL. On deeper "no deco" dives I usually have a look at tables or more often V-Planner and then dive on my computer.
My "Techie" dives are planned on V-Planner and I dive on a run time state with my VR3 as a backup (and backup tables as well)

In the old days I used Navy tables. They were the only thing available.
In getting re-certified, my wife and I learned the air tables in our OW class, and the Nitrox tables in our Nitrox class. We know how to use tables, but NEVER use them. Our computers are reliable, they track our actual dive profile, they give us much more dive time, they give us much more information, they are good for any Nitrox mix, they give us information during the dive, they store dive info for later download and use, and they are easier to use.
For me and my kind of diving, tables are of no use at all.

It's tough question (in a sense) to answer. To reply that one doesn't use tables seems to imply a lack of knowledge and a simply reliance on a computer and it's algorithm.
To reply that one does use tables seems to imply using them as taught in OW class and implies strict adherence.
Planning using a table with the use of a computer during the dive only makes sense for a square profile dive.
I get the point of this thread (I think) but the answer for me would be that I wear one and sometimes two computers on a dive and base my profile primarily on the single dive tables in my head and adjust that info in a conservative way for multiple dives.
In many cases that's not even needed in which case the computer on my wrist is just being used for time and depth.
I think this poll is directly more toward those pushing for the longest possible dives in order to maximize their money while on vacation dives or perhaps while on local but expensive charter dives.
Even in those cases though I dive the same way so I guess (for me) there isn't a clear cut way to answer this question (poll).
When I use two computers I generally have one in computer mode and one in gauge mode. When I only use one computer it's generally in computer mode but I'm generally directing my gaze at the time and depth info.
I guess the poll answer for me would be "other" but I suspect this is how many are actually diving even if they made other choices in the poll.

Most of my rec. diving is very multilevel. As such the tables just became too limiting after computers became commonplace. So for some time now I just use the computer. On the other hand, I'd also be happy to do 99% of these dives with just pressure, time & depth info.
If I was doing a square profile, I'd be happy to just use the tables alone.
If I was going away on a multi day dive trip I would take a spare computer.
If the moon is in the 7th house, I hide under the bed.
On deco dives I plan with paper, pencil & desk top planners. Then I dive my computer.
And I make sacrifices to various voodoo deities.

I like to use the RDP as reference. I always check the NDL for the depth I plan to dive, just in case my computer decides to take a vacation. I always wear a dive watch for redundancy, but rely on my computer when diving.
