Windforce has them... but most are now going for the Locosys GT-11. It has twice the features, 10 times the memory and half the price. Windforce have those as well.
Oh, I forgot to mention.... it is 10 times more accurate. The foretrex measure only to the nearest 2.4 metres. Even at world record pace of 24m/s that is a 10% error.
The GT-11 uses Doppler and is accurate to 0.05 knots
The Velocitek SC1 GPS costs A$550 , about 4x the price of the GT-11. It does not have the windsurfing features of the cheaper unit such as Speed Genie.
