Damn, that tracker is huge! I'm surprised the thing can swim around with it.

  The beauty of working underwater is that you can get things like this to neutral buoyancy. Most of the effort that we experience when moving an object above water is force exerted against gravity (vertical, compared to horizontal effort).
