Review on 🔭 TKKOK D80 Night Vision Binoculars: Advanced Goggles for Adults in Complete Darkness - Military, Spy, Security, Hunting, Tactical | 1080P, 4X20 Zoom, 3000m/9840Ft Viewing Range by Sri Wells

This is the first night vision scope I have used so I don't have a link. The device works as described. I can see clearly in a completely dark room. At night he will see as described. I didn't know the distance yet. Adjusting the zoom, focus and IR beam diameter takes a little practice to get a good picture. After adjustment, the display quality is good. If you change the zoom, you have to refocus. It's no problem to do it. Using it outside at night I could illuminate a house about 100 meters away to see the whole house or greatly enlarge a side door. No one could walk through the door unnoticed. I'm going to connect it to an external power source instead of feeding it from batteries. The manual that comes with the device is in terrible English. It's nice, but not strong enough for my taste. Place it in a Pelican case for safekeeping.
