I'm only speculating but since the receiver is aware of elevation changes, wouldn't it be able to calculate the change in distance both vertically and horizontally over time to determine velocity? Seems like a pretty simple calculation. (sqrt(v^2 + h^2))/time = velocity

I've never tried it but I think this is what you want: G7ToWin "The program supports download (transfer from the GPS to the PC) of waypoints, track logs, routes, events (Lowrance/Eagle units only), and for those units which support it, downloading a copy of the current display as a Windows bitmap. "

When travelling downhill, (ie skiing, snowboarding, cycling) is your speed measured relative to the slope or according to the horizontal? I've just ordered an eTrex Legend and haven't been able to try this for myself. Not so much a concern on my bike since I have a speedometer but it would be interesting to know how fast I'm going on a snowboard. Thanks!
