As the Distributor for DECOM I can respond to the above questions. 1. MSDOS (3.1 and up), runs under Windoze. Unix, Mac, Windoze 95 "soon". 2. $69.95 (s&h is b.s) 3. Buhlman 16 4. Air, Nitrox, Trimix and Heliox. Limits are self imposed, tables are an= =20 artificial construct designed to try and present information on something= =20 we don't truly understand. Used to 450 fsw (trimix). 5. No demo, for $69.95 just but it. Ask some of our users about it. > Lastly, but most importantly - do they work?

Our philosophy basically is to spend a few more= =20 minutes in the water and skip that inconvenient trip to the chamber. We=20 do however accomodate O2 usage during your SIT if you want to trim the=20 conservatism down a bit. If you want to get out of the water quicker,=20 just get out, you don't need a computer simulation to "allow" you to do so. On the other hand I think that ALL of the programs have been compared to=20 a large collection of no incidence dives with favorable results. Most=20 recently we have acquired tha data the USN is using to develop their=20 statistically based decompression algoritm and will run DECOM against all= =20 their positive dcs incidence dives to see how close DECOM would have had=20 you to that profile. On my way to F L A r.b.
