My ideal unit would display depth and time (seconds included) of course in fairly large numbers, and maybe temperature, but in addition it would have a stop watch feature and depth averaging which could be restarted by pushing a button, dive recording for uploads, backlight and it would be about the size of the Timex Helix dive watch and work to at least 200m, but the deeper the better. Also, you should be able to choose imperial or metric units. I think the Aladin Tec is the closest you can get to that right now and at a little over $300 it's still semi-reasonable given what other units out there cost. What do you think?
