Alti-Force Sensor Pack - GoPro Addon

By adminon - Read 10099 times

With the increased popularity of action cameras over recent years it's not surprising that we've seen an increase in the manufacturing of third party hardware that makes use of the GoPro camera to add additional value to users. Hypoxic recently released their Turned On product, which allows skydivers to see whether or not their camera is recording or whether there's any errors, without having to ask their buddy.

The company Alti-Force has just released a product of their own that attaches to the GoPro camera and like the Turned On device, will seek to add some extra value to skydivers. When in use the Alti-Force Sensor Pack will be able to overlay information about your flight over the video. The device is able to record and display both altitude and the acceleration/G-Force of your jump.

The visual representation of Gs can be useful for those looking to maximize performance, by using the information to identifcal optimum body positioning and technique.


  • Subtitled video playback for your GoPro® camera

  • Altitude subtitles selectable as feet or meters

  • Acceleration G-force subtitles selectable as X-Y-Z axes or total magnitude

  • Compatible with GoPro® Hero4 Black and Silver, Hero3+ Black and Silver, or Hero3 Black

  • Fits in GoPro® cases with BacPac™ backdoor² (not included)
