Document: was very good i loved the sight it gave you so thank you i really enjoy the product! Thanks Have a good day
very good product for the money. Arrived in a timely manner and works well around the back yard. I have not taken out on any late night trips yet.
if the object isn't right in front of you, this thing is just not going to see it. I can't figure out how that is helpful. I have seen nothing with it that i could not see with the naked eye at any reasonable distance. The biggest mistake i made was in not returning it right away.
We bought property in the mountains and wanted to watch our critters. Works just great. It's quite a strain on the eyes but that's the technology.
This unit replaced an older unit from another company. It works very well. Does exactly what is says it will.
Its like a little black and white TV screen which takes a second to turn on and come into focus. After that it works real well, the objects are much clearer with a lot more definition. I would buy this again. Wish it had a rubber eye cup, other than that I am very statisfied.
I really had high hopes for this. I have another Sightmark product which I love. This one, not so much.
I read the reviews about how digital is nicer than GEN 1 night vision. That's an understatement for sure. It's WAY better. It's almost on par with the GEN 2 night vision at a fraction of the cost. I highly recommend it.
I purchased this as a Christmas gift for my boyfriend. He loves to hunt & took up deer hunting this year. I took my time and read about several night vision units as well as the reviews for them. After weighing all the information & reviews I felt this unit was the best for the money. He said its a good tool to have when hunting at night & would be a huge advantage hunting coyotes. Would be nice if it had a wider field of vision.
I am familiar with night vision equipment, and while difficult to use, I feel that I know how to use and can deal with the limititations,  However, this unit just did not work!
