Get the Black Flash. I have 2. I wouldnt trade them for anything. If your going to spend the money, get the black flash. If you want a red-glow cam, get a cheaper one. No sense in getting a nice expensive red-glow camera, in my opinion anyways!
I have watched mature bucks stay or walk past my salt lick for over 8 hours in one night...never to leave the camera site for more than 20 minutes. I never would have guessed a deer would spend that much time on one ridge in one night. I also wouldnt have known that if I had one of my red glow cameras sitting there. You learn alot about deer behavior. It is well worth the money.
