The Qstarz 818XT High-Speed GPS unit is the ideal combination for us with lap timing Apps such as RaceChrono and your Android mobile phone. Normally these Lap Timing Apps will not work very well at all when using the phones internal GPS as it is not efficient or fast enough at acquiring satellites. This translates to bad data and poor lap timing accuracy. When using the 818XT unit in conjunction with an Android phone and something like the RaceChrono App, your data will be 99% spot on, which is more than enough for accurate Lap Timing.

The 818Xt unit can even be used to improve the navigation on your phone through apps such as Bluetooth GPS which allows you to connect this GPS receiver through to your navigation software such as Google Maps or Hema Maps, for a far more accurate and consistent experience that does not require phone signal to work.
 Ideal for 4WD navigation in remote areas.

Please note: will not work with non jail-broken iPhones

Good for lap times

By: on 18 February 2017
I found the Q818XT to be great if you want accurate lap times & will give a reasonable amount of data to work with on average to see how your riding performance is going, but I have noticed that it can occasionally give some misleading data showing a line that definitely wasn't taken & that also result in a spike or drop in speed which will also reflect into incorrect lateral & longitudinal acceleration readings. I have tested this unit at both 10hz & also 5hz with DGPS enabled. Data was recorded using Racechrono Android app & later exported & analysed using Racelogic's Circuit Tools 2 software. Bottom line: Good enough for accurate lap times, but can give misleading data on tighter parts of the track.
