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 Garmin Virb or Virb Elite Video Camera. Most digital recorders have a 3.5mm AUX In for recording, however with the Garmin Virb they use a Mini USB port for recording. This adapter connects directly to the Garmin Virb Mini USB port instead of a 3.5mm port.
This adapter WILL NOT work with the GoPro Hero3.
