If Marty McFly had hopped on a surfboard instead of a skateboard, this would be that surfboard. The aim of the Pukas/Tecnalias Surfsens Project is to “turn feelings into facts and figures and provide as yet unquantified data that can be directly applied to improve the features of surfboards, the technical performance of surfers and/or measurement of parameters during competition.”
Early adopters: You have your H-Bomb. You have your Phantoms. Now you have your surfboard. iPhone dock not included.
