GPS Speedsurfing is a lot of fun. You can see immediately how fast you go and it is possible to analyse the data in a computer program. But this can be quite technical and there are a lot of parameters to think about. After a lot of testing and analysis we have decided to set a few 'rules'. This has to do with the setup of the GPS, Software use and the data that�s derived from the GPS/Software. These 'rules' are not rigid. We know that GPS has a lot of potential in different way�s and there is a lot of development being done. For now we have a lot of confidence in the way we operate. After more than 600 postings on our forum and the analysis of hundreds of tracks from more than 60 different speedsurfers we can say that we know what GPS speedsurfing is.
