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.
