You’ve got to see this watch by Garmin. Unbelievable built in GPS watch that could save your life, or at least get you where you are wanting to go. http://sites.garmin.com/quatix/
QUATIX™ features a built-in high-sensitivity GPS Garmin navigator. You can actually load it with routes, mark waypoints, and it can guide you to your destination and back again. In addition, you can use sight and go navigation. Pick a point in the distance you wish to navigate to, set quatix and it will keep you on course to it. This is especially helpful for kayakers and canoeists.
