The design of the all new FREEDOM+ Surf is the result of collaboration with Ocean & Earth and 2 x World Surfing Champion Tom Carroll, here Tom provides an overview of the key features. The removable power module with LED indication for power on/off and battery life, is housed in the custom designed Ocean & Earth tail pad kicker, enabling you to move the power module easily between your boards and for recharging. The all important antenna electrodes have been designed into a sticker thin adhesive decal applied to the underside of the surfboard. With a weight of just 250 grams and a near zero drag adhesive decal antenna (only 500 microns thin), there is no impact on your surfing performance
