These are great night vision binoculars. Mini size for easy portability and would easily fit into cargo pockets. I like the rechargeable feature because it saves on buying batteries. Just charge with included cable using a phone charger or power bank etc... It has multi level brightness and IR sensetivity for different ambient lighting situations. The lens is adjustable focus, just turn for you specific need and a digital zoom. The included 32g micro SD card and card reader is a very nice extra so you are ready to go right out of the box. It also comes with a wrist lanyard to carry the binoculars and prevent from dropping it. A velvet type bag is also included for storage for dust protection and tidyness when not in use. They even work in total darkness which is spectacular. The color viewing screen is a great size and it takes still photos and video. There is also a color enhancing feature which is very nice for photography. Hunting camping fishing and surveillance are a few reasons to have something like this. Viewing movement around your home at night for security or watching animal movement anytime like dear or anything else you may be interested in. Anyway you look at it these can be extremely handy to have and you won't go broke buying them because they are an exceptional value. You can't go wrong with these and I'm very happy with their performance.
