Alti-Force SP30


Upgrade your GoPro® video camera to record 3D action with video!

  • The Alti-Force Sensor Pack attaches directly to your GoPro camera for recording altitude/elevation and acceleration G-forces.
  • The Alti-Force GPS mobile app is also available to complement the sensor pack and add GPS speed, distance, and heading (bearing) to the recording.

No post-processing required, record then play.

  • The chosen data are automatically saved in a subtitle track for display during video playback (raw data and GPS tracks can also be saved for analysis or map overlay).
  • Subtitle tracks can be enabled/disabled in a compatible player’s settings.
  • The video remains unmodified in its full quality form; subtitles and data are saved in separate files.
    (Note: video editing may require additional steps to retain subtitles)

  • Internal 30-pin Hero bus extension port (accepts 0.5mm pitch FFC ribbon cable)
