External stereo microphone for improving sound quality and recording targeted audio.

The mic connects to the rear of the HD170 camera (all versions) and is perfect for eliminating wind noise, for helmet commentary and for recording sound from a source away from the camera location.

When connecting the external mic (or an external power source), the rear hatch of the camera must remain open. The silicon boot fits snugly over the rear of the camera when the hatch is open, protecting it from dust and the elements.
