I use a sight light when I shoot indoors to help pick up my pin. Its a .010, so hard to pick up in no light/low light situation. Its not a wrapped sight, jus about 1" of fiber. Anyway, it came with a light and that light sucks, after a few shots it will turn off, batteries are always dead even when I haven't been using it. things like that. Want to replace with a good one. Any recommendations? The G5 universal fit one looks like a winner from internet research.
