Ray Vision System. Duluth: Dr. X, ca. 1997. An electronic system which allows a performer to see through certain types of opaque materials, including envelopes, cards, boxes, and more. The system makes available to the entertainer or his partner virtually any secret information, making it a tremendous tool for psychics, mindreading acts and magicians. Objects placed in an opaque box can be instantly seen by the performer or his partner, even if the performer is in a separate room from the proceedings and box. Additional applications allow the performer to instantly know cards face down on a table from a distance of as far as 50 feet, cards face down in a box, every card held in another person’s hand, what cards are coming off the top of the deck, or the identity of the hole card in Blackjack or Five Card Stud. It is equally easy to instantly and covertly obtain access to any information written on an opaque clipboard. The system can be used by one or two persons, is self-contained, sets up quickly and can be easily transported. Originally sold in limited quantities and includes all necessary apparatus (clipboard, two boxes, special cards), as well as electronic equipment, chargers, custom carrying case, and instructions.
