      Subsurface can track single- and multi-tank dives using air, Nitrox or TriMix.
      It allows tracking of dive locations including GPS coordinates (which can also
      conveniently be entered using a map interface), logging of equipment used and
      names of other divers, and lets users rate dives and provide additional notes.
