I'm interested in others thoughts, opinion and experiences. I've been using a pair of rangefinding bins ( Leica ) for a couple of months now. Great bins no issues there. What I have noticed is that I can watch a beast going about their business but as soon as I check its range the head is up. Happened again last night. Was watching a beast for 15min, ranged it and the head was up looking straight at me. It didn't move off but it kept checking me between mouthfuls.
i am aware of their sensitivity to the UV spectrum but can they also see the beam used in rangefinders ?
i look forward to hearing your thoughts.
