Range finder are great tools to have. Often when bow hunting there isn't always time to use the range finder though. I keep my handy and when the opportunities arises I range terrain to be prepared. My personal opinion is the range finder can actually hurt bow hunters in the long run. I found that it made me not recognize yardage as easily since I was always using the range finder. Pre-ranger finder days I was able to quickly look, draw back and feel very confident in the distance I estimated. I have been focusing shooting more 3ds events and walk throughs and trying to use the range finder less to improve yard estimations for hunting situation. Also, I added a QAD rest to my bow and finding this will be another step to take before shooting the animal. My point is between binos, ranger finder, knocking and releasing, etc there is more opportunity during spot and stalk to actually slow down the shot reaction time. I still will carry one just be more mindful of estimating yardages vs relaying on the range finder as much.
