I am afraid the battery of my phone would give up if I used Bluetooth and GPRS for 2 hours continuously. May I ask what kind of phone you were using? Good luck for the show! I am sure MMT will be a great success. 2008-02-29 {screen_name} http://www.mapmytracks.com/explore/track/dinghy-sailing-show1/746 Thanks for your kind comments Zsolt. We used a Nokia 6110 Navigator which has an internal GPS receiver for this track. Two hours is about as much as this phone can manage for continuous tracking before the battery dies. 2008-03-03 {screen_name}
