I saw a video once that came out of Europe somewhere. Germany or England maybe? Anyway, it was a couple of guys that hunted barn rats with air rifles. They had some night-vision-equipped air rifles and would climb into a high place in farmers' barns. They were shooting video through the night scope and it was amazing footage. I can only guess that the farmer was paying them to eradicate the rats. They would kill hundreds of rats in a single night and the action was non-stop. Like a shooting gallery. The gunshots were quiet enough that the little vermin wouldn't scatter, but would just look at the rat next to him that was suddenly break dancing for no reason.
If I had access to a rodent-rich barn, I'd buy me a set-up like that in a minute.
More than likely it was the ATN x sight it is a day/night scope and can record pics and video while you shot and also has wifi so someone with a iphone or ipad can watch along with you.
I have one just havent had the time to get out and use it.
here is a link to the scopes http://www.atncorp.com/smart-hd-weapon-sight
