ATC 1000 Helmet Camera -- On the riggers
He attached the camera to the riggers (the part that supports the oar) on their shell (aka the boat). The white box thingie is a speaker to help out the coxswain (the person yelling commands, encouragement and counting off).
Video is cut short - but you get to see them start off in their power 10. At one point you can hear them catch their rhythm and everything makes nice sounds :P
Video is not as good a quality as the raw footage (too big to upload :P). I think this convinced my buddy to find one of these cameras too :P
