    It's just fun to mess about with these things.

    Bit of a thread resurrection - but how does a normal basic android smartphone with GPS/AGPS/GLONASS compare to a basic Data Logger as proposed by the original poster, as the source for the GPS track? Is a Data logger more or less accurate - are either good enough to be useful for windsurfing?

    I usually have an old nokia phone inside my wetsuit for emergencies (it can be pretty quiet windsurfing on UK south coast mid week in winter), and was thinking of swapping it for a budget smartphone so that I can get the data track, and also be tracked remotely. There are apps that let you configure the power/on / off button to send an SOS message including GPS coords, when pressed in a specific way.

    GPS accuracy mostly depends antenna type and location. So different device differs because it. Trackers do not have screen so it can have "better" antenna.
    Old android phones too slow to records 1 measure per second, so external trackers do it better.

    And at last - my app do not records track at all ), you can use any useful GPS tracker to you with it. )

    I like the track analyzer! I usually track the sessions with a Garmin watch and use the App SyncMyTracks to load the tracks on my smartphone. With the track analyzer I can then easily see all windsurfing information, like 10s runs etc. But I wonder that for example speed max is different from the speed shown in the Garmin software. Sometimes the difference is small, sometimes it is more than 10 km/h. The same for the 10 s runs if I analyse them with the GPSResults Software for example. Do you know why the same dataset can create different speed results depending of the analyzing software?
    Kind regards
