Like DNS stated. The nice thing about video is you can review and learn from the past. I learn a little each and every time I go out. And value these videos as one of the best educational tools. It truly eliminated the second guessing. And will help me master the art of running follow up shots on hogs and coyotes.
I highly recommend getting the best mini DVR you can get. And learn how to use it. That also takes some time to master.
DNS and I were talking about this last week. Apparently, neither of us has mastered recording yet as we both forgot to turn on our recorders on different hunts. At least the other one got footage. Recording seems simple until you do it. Seems there is always something that happens. I read where one guy stated a week or so back that he hunted too hard to record. I had to chuckle.
Recording is much more than making videos to share. You can slow them down to fractions of seconds and learn what actually happened. It has been a tremendous tool for me. It really lets you know where you need work. I don't leave home without it...
