It may be time for overworked caddies to find another line of work. The Shadow Caddy is a three-wheeled electronic device that carries golfers’ clubs without a remote. It works by a tracking system and simply follows you and your transmitter around. So far the caddy is only available for rent at Australian golf courses, but we are certain they would love to hear from anyone who wants one enough to import it to his/her countries. Check out the videos on their site to see the Shadow in action.
