Forget a computer, theres many of us happily diving on tables. A far cheaper option.
Tables are only good when you know the exact profile of the dives - and people will argue that "plan your dive, dive your plan" which is fair but the recent trip to Sharm changed my mind a little. Here goes...
Week in and week out, we dive the deep wrecks off both coast of UAE ranging from 70 to 110m. It get to the point that I memorize the typical deco profile of each wreck, and don't even bother to pull the Wet-Note out.
However, when I was in Sharm diving with some friends to test the Sport-KISS, we were planning a max depth and max bottom time (i.e. squarish profile) for bail-out gas, etc. but we don't actually follow the plan exactly based on what is interesting along the bottom/wall. Of course, we don't exceed the max depth or max bottom time, but we do shift the profile somewhat in the intermediate range. The guys I dove with have VR-3 so I simply follow their deco profiles - while referencing my own tables and make on-the-fly adjustments for comparison.
In those situations, simply following the tables for max depth and max bottom time will end up with a lot more deco than necessary as I have compared on those dives. The actual difference will (of course) depend on the depth and how the bottom profile was shifted.
Just food for thoughts...
