Free KA72 Speed Reader
Welcome to the Free KA72 Speed Reader. When you upload your speed sailing file here, basic stats are calculated free of charge. Anonymously uploaded files will be available for checking for a period of two weeks. Google Earth overlay of the track is available indefinitely.
All GT-11 tracks recorded after 1st January 2010 will now have their Alpha scores calculated using Doppler readings. Please ensure your firmware is up to date if using a Navi GT-11.
