You should monitor the batteries carefully. My Nemesis II Nitrox "lost" a dive (ie failed to log it) when I failed to notice the TU battery had gotten pretty low in the middle of a week of diving. I now always carry 2 sets of spare batteries and a backup computer. > Another problem we are seeing is with the PC interface. Quite often the > tank unit and PC are unable to establish a connection.

Usually I have to rotate the probe in the TU clips to ensure a good connection between the TU's screws and the metal bands on the probe. If I manage to get "dcitest" to recognize the probe twice in a row then there is a chance I can make connection with the "analyst" after 2 or 3 attempts, but then only after it negotiates its baud rate to 9600. Perhaps the part I find most frustrating analyst interface. I hate the way it spews out a meaningless comm error then kicks you back to DOS without asking if you want to retry. I already called Cochran and gave my feedback. They assured me it's being worked on.
