This is the children’s spy toy that lets young secret agents observe subjects in total darkness from up to 50' away. Using the same infrared LEDs found in home security cameras, it has two 5-LED clusters arranged on either side of the objective lens that illuminate subjects without detection, for nighttime spying on an enemy treehouse or identifying a pet’s favorite nocturnal patrol routine. With a power boost button for increased infrared light, a daytime/nighttime switch, and control wheels that adjust eye cup width and focus. Requires four AA batteries. Ages 6 and up. 8" L x 7" W x 3" H. (1 1/4 lbs.)
