Thank youI have a Armasite Zuess 640x480 x75 it works very well. I've shot Beavers at 200yds. With. But my son has kidnapped it for night coyote hunting. So I have a Burris BTS50 should be here tomorrow. I will post a report on comparing it to the Zuess. I have BTH35 also it works very well. Id's Rabbits at 160 yds and coyotes at 300 easily.
