It's great for creating your own aerial videos without excess cabin noise. It will record all of the audio transmitted through the intercom system, including in-cabin audio and ATC transmissions.
This is a special adapter made exclusively for use with the Contour+2 Video Camera.
Most digital recorders have a 3.5mm AUX In for recording, however with the Contour+2 they use a 2.5mm port for recording.
This adapter connects directly to the Contour+2 2.5mm port instead of a 3.5mm port.
