Some more food for thought:
If the technology for computers wasn’t superior to using Brass & Glass with tables why would all of the sanctioning bodies gone with computer diver open water certification programs?
I’ll agree with those that may say it is a dumbing down of the program. However the numbers don’t lie and they say that properly trained computer divers have few incidents and accidents.
Now take the one additional step add in the wireless technology. All it does is replace the pressure gauge and in doing so allows the computer to give us many more features. Just as we don’t have the Brass & Glass pressure gauge glued to our mask for constant viewing we also don’t need the computer to tell us pressure 100% of the time. Just as we monitor the B&G based on how long since we last looked, the depth we are at and whether the tank is towards the beginning of the dive or closer to the end, this is also the criteria for judging the wireless and how fast it reacquires signal.
If the statistics for computers were not at least equal to Tables/B&G then the computer manufacturers and sanctioning bodies would have opened themselves up to litigation from accidents using computers and this has not been the case.
