The Sonocaddie V300 GPS features an overhead map of the course showing you exactly where you are (and the hole that lies ahead) and gives you distances to hazards and to the green. You can calculate the distance of each shot you have hit, as well as being able to record your score. The V300 can record locations for every shot so you can review your round. The first five downloads are free followed by various memberships, which start at £3 per course.
This distance-measuring device contains a vast amount of information and features an excellent colour screen, which gives a full map of the hole you are playing. While the unit is easy to use the download system is more complicated than others.
