I have the second generation red dot sight from tactical archery systems. I got it on Christmas day, have used it for a week but decided to go back to my single pin sight. The sight is in great condition, it is just not for me. There are no batteries needed, the fiber optic cable projects the dots on the lens. If you want a picture let me know, otherwise you can go to www.tacticalarcherysystems.com to get the full breakdown and pics. Pm or email me if interested.
