GPS For Mariners is a comprehensive guide for recreational boaters to learn how to operate and effectively use today's GPS systems in everyday navigational situations. While all GPS products come with operational manuals and there are books on how to use your GPS for land or aerial navigation, there is very little information available to recreational boaters on how to best utilize their GPS for marine navigation. From learning the history of GPS, discovering the functions of the GPS, understanding basic and advance course-plotting, learning advance navigation with GPS, interfacing a GPS with an autopilot, to using a GPS with electronic charts on a PC, GPS For Mariners includes everything the novice to the more experienced boater should know about their GPS system. GPS For Mariners is the ultimate how-to guide and ready reference leading to GPS proficiency.
