Thread: Laser rangefinding with GPS linking

The problem ive found with “project waypoint” on Garmin is getting an accurate bearing. Astandard Silva magnetic Compass can only be read +/- 5 degrees which is quite a lot sideways when projected out 300m. I lost points in the Hihitahi challenge nav stages due to this. And Ive been let down when the gps compass bearing was out of calibration ( need to do the twirly rotation procedure) .

In geometrical theory, if there is significant slope and you use line of sight distance then you could over project for distance. Im not sure how much of a problem that would be in practice but a range finder with inclinometer and TBR capability would take that in its stride.
