The best out there - ATN ThOR 4 7-28x75mm Thermal Smart HD Rifle Scope

I've bought it when my Pulsar Trail XQ got damaged in a car accident last year, so I can compare. These 2 units are quite similar: they both have mathematical range calculation model instead of a laser rangefinder, regular firmware updates, video recording, WiFi streaming and remote controls (for ATN, the remote control has to be ordered separately, but it's worth the investment if you want to avoid extra movements). This last ATN model has an amazing battery life, roughly twice longer than Pulsar, about 15 hours or so. And ATN scopes are in a metal housing, while Pulsar made the scope body of plastic (I know, most scopes are not designed to survive in car accidents, but if it was metal, most likely I would still use it). And also, ATN provides a ballistic calculator that makes the reticle adjustments based on a ton of ballistic and environmental factors, Pulsar didn't have this option. ATN has recoil activated video, as far as I know, none of the other scope producers have offered an alternative to this feature so far. Actually, I only miss the picture in picture function that Pulsar had and ATN doesn't (it took some display space to show the target at the crosshair in greater detail and it was awesome).
