Once you get the hang of a GPS, it becomes easier to control and function. But, when you are first using a chart plotter it can be confusing. If you follow these simple steps, though, you will be a master in no time. To begin, set your first waypoint. If you do not know how to look inside the manual as it should say which button to hit. Your first waypoint (which is a position on the chart) could essentially be your starting place and from there, you could set the next waypoint to your desired location.
To prevent yourself from having to route the full destination, which you can do by setting various waypoints along the way, if the device has it you can click on the “Go-To” function. This will provide you with the direction to go and the remaining time to reach it. It really is as simple as that and you can add as many waypoints as needed.
