Hi!
I have a GT -31 for speedsailing, but also want to use it to show laptimes around my motocross track. Does anyone know of and how I can do this?
I am thankful for all help I can get.

You should be able to work it out, looking at the tracks and the speed graph.
I think realspeed, gpsarpro and speed results will show them.
Possibly realspeed would be easier, because if you select a lap on the track map, the speed graph and data table are also highlighted, all you have to do then is subtract the start time from the finish time.

gpsarpro doesn't select all the other views when you select on one. not sure about gpsresults, I haven't used it much.

Yes I hope I will be able to figure it out... But actually I was hoping there was a way to see it on the GT31 screen. Perhaps by adding a waypoint or mark or something and then get a timestamp for everytime I passed that spot. Any help would be great, we are also hoping to time our slalom course so we can compare each lap.
Thanks
