IMU

“An inertial measurement unit is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes and also magnetometers.”Source The IMU's purpose is to give us a signal that can be used to identify what the surfer is performing on the wave. Much like in a smart phone the device is capable of capturing and identifying 9 degrees of movement.
