The Garmin 7616xsv Chartplotter: Why every navigator needs it?

A Garmin 7616xsv chart plotter is an electronic navigation system that combines a GPS receiver with the ability to display electronic sea charts, allowing the boat operator to continuously control the movement and position relative to the physical environment surrounding, both below and above the water. Many boaters often refer to a plotter simply as a GPS unit, but I like to keep things a little salty and refer to them by their most appropriate name.
