I have two ATN 4k pro’s and have zero regrets or buyers remorse. My only tip for the ATN is use a high quality SD card and NEVER try to open the firmware file (.bin). Windows can and will corrupt the file if you try to open it. Besides that, the scopes are fantastic for recording day and night. If you use at night make sure the illuminator wavelength matches the sensor for best video quality. I use mine for hunting everything from squirrels to hogs, as the multi-profile allows for quick platform/gun changes. Had to get a 20moa rail for the big bore because the drop was pushing the adjustment limits, but thats not limited to this scope as others needed the rail as well. Just my 2 cents, happy shooting!
