The STX is our go-to spotting scope. We prefer the straight-line viewing this scope offers, and the rotating body enables us to perfectly match head height as we switch between binoculars and spotting scope. We find it mission critical to have the shortest possible change time when we switch from finding game with binoculars and evaluating with the spotting scope, especially in nondescript or thick country where the views can be fast.
You can pick between 65mm, 85mm, and 95mm objectives - or the STX Module alone. Each offers it's own specialized performance set:
