Saw the lunar eclipse. Waterfowl that remain on the pond at night kick up quite a fuss. Very lightweight but capable nvbs.
They are ok for daytime use but were bought specifically for night vision. The night vision is very low quality and very blury. Spend a few bucks more and buy a better set.
Great night vision for deer, raccoons, coyotes and lots of turkeys. The function * take a bit to figure out.
The instructions are horrible. It's not very easy to use. Battery life doesn't last long.
