I went out this evening and shot at my deer target where I could barely see my pin. This is typically the same level of light the last 5 minutes while I'm on stand before I come down. I wasn't very impressed with the results. At what point do y'all decide it is too dark to take a shot at a deer? I typically look at my surroundings and if I can't make a shot further than literally right under my stand it is too dark. I have found that 20 minutes after sunset in the woods is about the time when it is too dark for my vision.
