Re: gear you take long range hunting
An EXTRA battery for your range finder, and keep it on you. I had my range finder go out on a Wyoming Antelope hunt and would you beleive, it was the one time I left my pack in the truck. Big mistake, I needed it! The result was a missed long range shot, as my guess on distance was way off.
In addition, Shawn Carlock's 1st video will give you some other good ideas.
