|: It's my Christmas present from my wife!! From satellite signals, GPS enables me to track my speed/position along trecks!!! It's good too for never getting lost. I'm not sure of the result, but I Will try it on ramp to estimate max speed.... ;-)
Just how well does your GPS speed meter work with skating? I have to admit that I am a bit sceptical. I's suppose the radar speed system I got is better suited.
