The big advantage is it will shoot at 120 and 240 frames per second. At 240 the resolution isn't so good but 120 fps gives a good idea of arrow flight. Note:- The video is further slowed in Windows Movie maker which allows 0.5, 0.25 and 0.125 speeds.
I couldn't resist playing about and mounting it onto an old hard hat, it took a lot of messing about to get it in the right place at the right angle so you can see an arrow go. You can see a hole above the temple of the hard hat where I first tried to mount it. I used the camera mount from a broken old camera tripod, I knew it would come in handy one day.
It's mounted to allow for the tilt of my head in my normal shooting style. I s'pose I could use my old camera on a tripod to get some video of me shooting with the hat cam on!
