In the last few years the quality of standard non-doppler GPS devices have improved a lot. For that reason we have decided that we approve non-doppler devices for the so called fun-rankings and day-to-day use. Altough results of non-doppler devices are often close to doppler-recorded session there is no way we can verify the actual speeds that have been recorded. For that reason we do not allow non-doppler devices sessions in our record rankings. More information about generic GPS Devices (-> www.gps-speedsurfing.com/default.aspx?mnu=item&item=gpsotherFor speedfreaks that already own a Android phone a good alternative could be the App GPS Logit, The App produces doppler speeds, at the same quality level of the old GT-11 .The App records Dopplerspeeds from the GPS-chipsets that are implemented in all recent smartphones, so the accuracy is comparable to a GT11, the only missing item is the Dopplerspeed-error (SDOP). For record purposes it is not suited, however, for fun rankings it is way better than e.g. positional data from standard units.
