    Have been using this at my work for the last 3-4 weeks skydiving. Altitude is very spot on, even in burble scenarios like initial exit, certain tracking positions, and docking on a student it’s very accurate and catches up within a sec or two. I have put this in an altimeter test chamber and recorded the footage while in the chamber with my Neptune and Galaxy and it was spot on with both of them the entire ascent and descent regardless of speed.

    Since it saves data as a .SRT file, the subtitles only show up on your laptop with VLC, KM, Windows Media (with plugin, link on this site) or direct to a TV, will not show up on the GoPro App or the LCD backpack/screen but an easy fix for me was to use an micro SD card reader and plug straight into my phone which made the video quality better anyways and takes a second. The DZ offset feature is awesome, as well as the temp and g force readouts, wouldn’t mind seeing a MPH readout also.

    Overall, very neat and awesome product for $70 if you ask me. Gives a form of altitude awareness while watching the video footage without having to pause right when an altimeter shows up in frame to verify altitude. Whether jumping with a student or a group this is an indispensable tool, especially for $70.
