Bought a Gopro......Great Design and Function
 

I went and bought a Hero 4+ Silver yesterday and I am amazed at how the quality of the video is. I went to our monthly black powder muzzle loader today and did some recording. The 1080P video shows really great right from the camera through a HDMI cable and it has some great software that recognizes the camera and automatically copies the videos.
They are in MP4 format which is handy.

I remember the first camera I installed in my 914-6 vintage race car in 1998 and it used a VHS tape recorder and a regular Sony video camera. The whole mess probably weighed 10 pounds or so. In 2002 I bought a much smaller camera that was designed and made by some sports car racers on the East Coast. It used a Sony recorder and all weighed about 3 to 4 pounds. I sure recorded a lot of races.....

This one weighs nearly nothing, the batteries a super small and provide a lot of record time and a 64 GB micro SD card which are super high capacity! I am making up a mount to let it sit on top of the stock and look down the barrel of my Gibbs muzzle loader.
