These children's night vision video binoculars earned The Best rating from the Hammacher Schlemmer Institute because they provided superior image quality and night vision. A panel of children tested the devices and The Best model proved to be the easiest for little hands to hold, focus, and view images. Using The Best model analysts were able to read four lines of an eye chart from 20' away and three lines of the eye chart in complete darkness using the night vision mode, ensuring children will be able to perform nighttime reconnaissance missions. The Best models were the only binoculars with an automatic focus, they capture up to 640 x 480 resolution video and 2592 x 1944 resolution still photos, and have a 4X digital zoom, allowing young spies to easily record their surveillance. With 16 MB of internal memory; supports up to 32 GB SD cards (not included). Requires four AA batteries. 8 1/4" L x 6 2/3" W x 3 1/2" H. (1 lb.)
