I am keen to know my board speed. What is the right gps to get. I already have an etrex for bushwalking and one in my boat, but which one for Windsurfing?

NAVI

Think every body will agree, the locosystems GT-11 (navi) is the one to go for, it's one of the cheapest and most accurate and there's a lot of input from Australian windsurfers into the development of firmware, you can download the latest developments from Tom Chalko's Mt Best site, with details of how to set it up.
