The unit will give you the distance and courses from one waypoint to the next, and even an expected time of travel or arrival. In navigating the route with our GPS unit, you can select the Map, Highway or Compass page to guide you through the route.Īs you reach one waypoint, the course and direction to the next one will be provided. You will then have a permanent (if there really is such a thing) record of your voyage that you can summon and use to navigate again.
Now, go to the route function and compile these waypoints into a route. Then go to the next course change, and mark and save it, then to the next, and the next, and the next until you reach your destination. Mark and save it as a waypoint, and then go to the first turn in your course, and mark and save it as your second waypoint.
I prefer to designate my own routes, as the software does not know my boat’s requirements. In addition, some units with the proper mapping software will design the route using existing waterways, much as an automobile GPS unit would do using roads. It assumes you can navigate from one waypoint to another, to another, etc.
To make a permanent record of your route, you must actually make and save a route, which is made up from a series of waypoints that the GPS unit connects by a straight-line course.
