Mike, A few years ago, the Nemesis was sold as the Sherwood Sentry here in Canada. We had a unit which we tried at Les Escoumins in Quebec, the water temperature at 90 feet is just below 30F (salt water). On the second dive, the unit beeped and shutted off. Apparently, Sherwood removed all Sentry's from the Canada market. One of my friend purchased a Beuchat Maestro Pro last year. At that time, he did not have the software to turn off the cold water feature. When doing repetitive dives with the unit, it becomes way too conservative. As an example, on the second dive of the day, the unit started to beep at 60 feet, it got into gauge mode when arrived to 100 feet. Apparently, the unit was requesting for 60 feet deep decompression stops before going into gauge mode. This is incredible for two short dives that would require only a small amount of decompression by the Canadian dive tables. I admit that the problem was corrected when the software was received. However, I think that cold water features should be better designed. Did I say that when the software was received, it allowed us to find out that the unit was mistaking the depth by about 10-15 feet at 130 feet? Some people say that they don't use their computer to monitor their dives or decompression status. I agree that we should not be dependent on any piece of equipment we have, but however, I would not dive with equipment which I believe to not be reliable. As far as I know, the Nemesis computers are not sold as mapping devices, they are sold as decompression computers. One other design problem that I see is that the computer limits are too accessible. I feel that a diving computer for technical diving should allow stops to 90+ feet (when under 90 feet, just use the audio alarm if required). If the computers thinks that resonable design limits are exceeded, instead of saying bye bye to the diver, the computer should be designed to terminate the dive the safest way as possible and log the problem in its memory. Finally, gas switch feature should give the responsibility to the diver to manually set the proper gas. A single button could allow as many mix as the diver would want. Furthermore, the computer could not be blamed of being on the wrong mix. Besides that, Mike, I admit that I like your device. There is nothing else today which is as much customizable to diver's requirements. I just hope that it will get improved before I purchase one for myself.
