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.

Emmett Brown used one of these in 2015 to watch and also photograph Marty McFly, Jr. and Griff Tannen from a distance.


  • 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.
