This is the most recent version of the X-Sight 5-18 digital day/night scope. It has the threaded ocular housing and threaded sunshade to go with it. Also has the IR illuminator. New in box. Takes good HD photos and videos. Has its own built in mount. Tracks elevation, has digital compass and can capture your shots that take down your trophy animals. Can link up to handheld device via wifi to see what the shooter sees. I bought the scope on a waiting list and in the meantime purchased a scope to replace it. This wouldn't work for my project but would be great for hunters or shooters that want to record their shots. They sell at $699 when you can get them, I would like $650 for this one with no line, wait or back order.
