A Kitesurfer who wiped-out in shark infested waters was able to use their Apple Watch Series 3 cellular calling feature to send for help by calling the coast guard. A recent Daily Mail report tells the story of kitesurfer John Zilles who crashed into water a mile offshore where sharks have been known to swim. Equipped with just Apple Watch Series 3, Zilles phoned home to let his family know he’d be in late then guided the Coast Guard to his location.
