Weren't they using this device for the measuring the Red Bull King of the Air jumps? I'd really like to know how well this works and if anyone is using it with Android software. :?:

Yes, they used 'em at KotA this year.

As far as I understand it, they're shipping the one which plugs into your iPhone now. The Xensr+ (which won't need to be plugged into a phone, and promises Android compatibility) will come later; there's no announced date on their website.

The other player in the ruggedized GPS/IMU market is the ActiveReplay Trace. They've been doing an alright job of keeping people updated with their progress since their Kickstarter campaign got funded. I contributed enough to the campaign for a beta unit and a full production version. Hopefully at least one will get here in time for spring. :)

Xensr should get the basics right first - height speed distance and airtime....

To activate gps and start recordind - i have to turn my phone off completely then reboot.
The flashing X doesnt work twice..
Airtime is fucked - 26ft jump on flatwater 3.4 secs, 41.9ft jump on flatwater was a wopping 2.6 seconds... Fark yeah :)
Downloaded n reload app n closed everything else too.
Theres a waterproof/shock proof disc style pne coming out - which would be better than taking your phone out and landing hard on that side...
I wish garmin would bring one out :)


So all of the KOTA results are shyte... :roll:

Always interesting with "height" measurement devices.

Many different principles can be used, and getting better and better !

When the Shadowbox came, I contacted them in order to hear about the accuracy (and what it was based on), but never got an answer.

Could be they just didnt care - or could be they did not know :roll:


I think the Xensr got them quite right at the Red Bull, as they seemed to match quite okay to what was seen, right ?

The absolute precision, and to know what circumstances can make it worse or better, is interesting.

I work in a calibration/verification lab daily, so very aware of why it is not that easy to explain the measurement uncertainty, as there are sooo many variables - and especially when handling huge accelerations like in a kitejump.

There are also a "normal distribution" error involved in almost every single case, which means the precision can be one range most of the time, and then way off a few times :naughty:

Really interesting device though - looking forward to hear more :thumb:
