The DJI Osmo Action Surfing Tether Kit is designed to securely attach your Osmo Action 3 or Action 4 camera to your surfboard for stable filming in dynamic conditions. The kit includes a flat adhesive base for easy attachment to your board, and a quick-release adapter mount that slots into the base’s 3-prong mount and locks in place with the included screw. Additionally, a surfing tether offers extra security, preventing your camera from floating away, even in the midst of powerful waves.
