Doc holding his binocular card in 2015.

"Doc reached in his pocket and pulled out a plastic card with a pair of eyeholes, and the words POCKET BINOCULARS printed beneath. It looked like some cheap, plastic toy, the kind of thing you'd find as a prize in a cereal box. The way Doc handled it, though, Marty suspected it was really a more compact, fully functional future model."
—From Back to the Future Part II by Craig Shaw Gardner (quote, page 19)

A binocular card was a rectangular pair of binoculars as small and as thin as a credit card, and also incorporated a camera to enable the user to take pictures of whoever or whatever was being viewed.


Dr. Emmett Brown used a binocular card in 2015 to watch and also take photographs of Marty McFly, Jr. and Griff Tannen at a distance — namely, from the end of the alleyway where the DeLorean time machine landed.


  • Digital cameras and camera-equipped smartphones of the approximate size and shape of the binocular card seen in Back to the Future Part II are near-ubiquitous items in 2015. The device Doc uses appears to have face recognition software, which is now a standard feature of many consumer digital cameras.
