Carl #The decisions we make should be well thought out and considered and, more #importantly, our dives should be *planned in advance*. We should not #normally get into circumstances that require "split second" decisions or we #have gone well beyond any "safety/buffer zone" that one normally employs #when diving *or* something catastrophic has happened and there often isn't #time to check gauges for information anyway! When this happens, the risk #for a problem is *much* higher than normal, whether you have an analog or a #digital gauge!!! Fairly good summary: unplanned-for emergencies will seldom give you time to use all the information you have to hand anyway. #Also, IMO, it would be much easier for an analog display to "get stuck" #than a digital unit. My cheap electronic watch has never got stuck. I have though tried to count all the trips I've been on where other divers' computers (including some with integrated air) have malfunctioned; it's getting towards 20 occasions. In that time I have not seen one single analog cylinder pressure guage fail. Maybe their comparative reliability will improve? Such facilities (air) are not in themselves dangerous: the problem is only when the black box becomes the sole source of information ... vis in general how many dive computer wearers ACTUALLY carry a watch and independant depth guage as well? Can any current, or planned, "air integrated computers" cope with inputs from more than one independant cylinder? Bob
