the company I work for has that experience (electronics, watertight and pressure related stuff) but I personally doubt there's much demand for such a device in the diving community. most people I can think of care for the tank pressure during the dive not afterwards. but we would be happy to develop such a device if someone is willing to pay for it :) of course, as Davide mentioned, kickstarter would be an option... need to think about it. /martin _______________________________________________ subsurface mailing list [email protected] http://lists.hohndel.org/cgi-bin/mailman/listinfo/subsurface
