These digital dive toys, dive computers, are usually wrong, and sometimes dead wrong. When I prioritize what makes me safe doing deco, this is what I come up with: #1- not having a PFO #2- being in great aerobic / physical shape #3- good hydration, being rested, and good thermal protection #4- planning the dive (on deco planner), with bracketing for depth and time #5- making a controlled ascent, with deep stops, and switching to the correct gasses at the correct depths. ie. 50% at 70fsw, and 100% at 20 fsw. Doing these dives in the Carmel-Monterey areas is not really rocket science. Thermal factors in our cold waters usually determine that most of the dive times are between 60-90 mins.. Take deco planner and run the numbers for depths between 150-200fsw. You will see that it doesn't take to long to get a feel for what your deco should be. Once you understand this, your health doesn't depend on an electronic gadget that is likely be inaccurate, and, eventually, fail someday while you're in deco. I don't think that safe deco is about calculating our stops down to the exact minute. I do think that it is about our body's physiology, using the correct gasses in the right places, and making a controlled ascent. Again, check the archives on dive computers, and decompression procedures. Dave -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
