It's quite a bit different hunting from a blind than when cruising through varied terrain. You have much more control
of your environment from a blind. I've also hunted for many years with a bow, and for most shots rely on my judgement.
But poor light, steep grades, and the 3D effects of surrounding timber can be very deceiving...that's where I would prefer to
use a rangefinder rather then make a poor judgement shot resulting in the wounding of an animal.
