Anyone tried one of the night vision cameras that attach to an existing scope? I think you get the camera, everything to mount it plus an infrared light. Looks like you mount your phone to use as a display. They run around 300 bucks and I'm sure would add a lot of weight. Some advertise a working range of 200 yds. ATN sells them as well but, are more pricey. Just curious if they even work or a waste of money.
