Home Forums Hunting & Shooting Hunting Optics Redfield Trackers, how do they compare?

A guy I know a little has five of the 3-9x40 Redfield Trackers from back in the 1980s/90s that he wants to sell. All have been used, but look good and the $50 per unit seems fair. I'm thinking that they are, optically speaking, about the same as the first series of Nikon ProStaffs.
