[PSUBS-MAILIST] instruments, pressure display?

[Joe Perkel]

Jon,<br/><br/>As a diver I would say depth. The reason being that in a blow and go scenario you need to know that last depth and time to blow down to know your bottom time for what would be hopefully, a controlled ascent. Think USN dive tables.<br/><br/>This is a big reason why I think I personally would limit my own personal maximum operational depth to 250' with a practical use somewhat less. I might design for a 1,000', but I'm not going there. I really don't think I would like to go any deeper than say something like the Andrea Doria in a homebuilt non certified sub. Conversely, I'd do Titanic in Alvin, Mir, or Nautile in a heartbeat if I got the chance.<br/><br/>Pay close attention to that next 25 story building you stand next to and picture yourself ascending from street level to the roof line. You may need to stop at the 24th floor for a while, if you can control that last ten feet that is.<br/><br/>Joe<br/><br/><a
