A mini mag is permanently attached to a retractor on my vest. I never know when I might need to stay out later than I planned , and farther than I planned. If I plan o nite fishing, I always carry a second mini mag and a spare set of batteries. And I think I have better than average dark vision. The last 35 years have been spent working in darkrooms, but when you are in the dark , in unfamiliar turf, bad things can happen.
