A:AnswerYes, the big orange floaty mounts to the waterproof screen on the back of the GoPro via double side tape which will cover my lcd screen. But I just use my Galaxy Note 4 phone to view and control the GoPro from.
A:AnswerThe sticky on the floaty is to attach to the wTerproof case for camera, not a board. You will need a different adapter for that. And be sure to test it in shallow water before you go out. The floaty is made to float the camera only.
