with mine I could shoot in the Moon light.
thats because the fiber is grabbing the ambient light. try a overcast early morning hunt and i would rather use a white dot than fiber. i dont hunt into the dark but i do know that tritium pins dont need sunlight or batteries. i have an erradicator sight thats 12 years old with tritium and its still working.
I've never hunted an overcast early morning
I'll stick to my Fiber Optics they are brightest in all conditions. I've also killed several Bucks between 10am and 2pm. I shot a Buck right at dark once. I won't do that again. If it's too dark to see your pins it is definitely too dark to pick a spot and accurately judge a rack.
If I'm seeing Bucks right at dark I figure I need to have my stand in a different location.
I always wonder why they made those Tritium pins. I guess some like them. I tried them and they were not for me. I don't know anyone in this area that uses them either. Fiber Optics are so bright compared to pins in years gone by. I've never had trouble seeing mine during legal shooting hours period.
