One of the limitations of the underwater laser scanner is the need to have it stationary, relative to whatever it is that you're scanning. To overcome that, and this sort of talks back to Mr. Hayes' discussion about the university's involvement, through another government program we were able to bring on a grad student through a sort of time-sharing with his research and his time at 2G Robotics, where we're developing the ability to create 3-D models of underwater environments simply from video. So you no longer need the laser in the picture and can just take video to create a 3-D model of the underwater structure.
