Reima Raty asks about table & computer use for technical diving.

Aquacorps #1 has some good articles on computer use for deco diving.

I personally use an Aladin Pro computer for decompression diving, and many
other people I know use Buhlmann-based computers for this.  I tend to use the
computer 
conservatively when diving or decompressing on air, staying 5-10 fsw below 
the indicated decompression stop depth, and then hanging at 10-15 feet for 
while after the computer clears me.  This adds a healthy safety margin to the
computer algorithm (Buhlmann), which is already somewhat more conservative than
the Navy tables.  If I am decompressing on O2 or EAN, then I go strictly 
according  to the computer for the stops on which I am on O2-enriched 
breathing mix, since that in itself adds safety.  Using an EAN bottom mix 
according to air tables or computers also adds a lot of safety.
