It's not often that tremendous advancements are made in the realm of binoculars, but these LightSpeed specs are something special. Aimed primarily at military / surveillance uses, this device is able to transmit video and audio via Infrared, theoretically enabling rooftop spies on opposite buildings to communicate. Furthermore, this method of communication is undetectable and untraceable. No mention of just how expensive these are, but suffice it to say, you aren't apt to see these on shelves of Toys R Us and the like.
