So I had a thought pop into my brain the other day that my spotting scope is a useful tool in the tool box but it would make more sense for me to have a kestrel and a leica 1600 range finder. I take the spotting scope with ever shoot but I find myself not using it as much as I become a better shooter and find myself making more hits. I find a lot of the times I am missing because of miscalculated ranges or possible weather data errors/inability to pull weather data for shooter/strelock. What are your thoughts on this. I feel I am making the right move. What did people use before Kestrels and rangefinders?
