Is GPS-Sport simple?
First, start and finish can be located in different places, that itself makes it problematic for sportsman to decide what order of control points is correct. Who ran “fox hunting”, knows it. Second, control points count is above 7-10. Easily found correct order of running through control points will be possible only with marking all CP’s on the paper map and keeping in mind relief. In fact it’s important not only to solve search geometry, but also to choose a route most easily run through. Those who does not work with map can in example crross river near the bridge or run on a windbreak parallel to road. Third, GPS-receiver by its principles can show true direction only if you are moving (because of needing to compute direction by using coordinates of two points). It’s easy to lost true direction to control points while standing and looking for something. Fourth, sportsmen have to consiber all aspects of propagation of gps-signal. The dense forest, hills or even a sportsman’s body ofte
