I’m not curious on how to use a rangefinder. Rather how fellow bowhunters stow one during hunts or access it when a deer does what deer do…. the unpredictable at times. I can think of many times when I’ve had opportunities to range a deer that took a path less chosen. -Or- one not expected that I’ve not previously ranged. I’m good with judging yardages. But I’m not comfortable enough with my bow setup (unless the deer is 20yds or in) with letting an arrow fly unless I’m absolute certain on yardage.
