Chris-

For technical diving of anykind your completely right, precut tables are the
right way to go. 

However I do not believe that the Oceanics deserve such a bad wrap, they
were never designed to be used for anything but recreational diving. Oceanic
worked with PADI on the algorithim so it works seamlessly with the PADI
tables. These tables were never designed for anything but shallow
nondecompression diving (<130'). I believe this is why once you go past such
limits in depth or time the units become so conservative. Hammering Oceanic
for the computer not being good for tech diving makes about as much sense as
slamming an Audi for not being a good 4x4 to cross the Rubicon with.

For OW diving the Oceanic computers are great, they have a proven algorithim
and safety record. Their display and use is the epitomy of KISS leaving
little room for mistakes by the casual OW diver. I always recommend theirs
or one of the many cosmeticly different (renamed units such as Dacor, USD,
etc) units to my OW students. Remember the average diver is not as
disiplined, informed or as experienced as most who are on this list. I make
nothing from the sales of any computer, this comes from the heart.

P.S. Sorry to hear you can not make it to the rebreather meeting next month.
