What’s A Garmin Marine Chartplotter And Why It’s Needed?

A Garmin marine chartplotter is considered an electronic navigation system (ENS) that uses both GPS receivers and maps to enable you to monitor the movement and position of your vessel in that current environment, both above and below the water.

How It Differs From A GPS?

Primarily, most GPS devices do not have maps or may not have easy-to-read mapping, and the chart plotter does. While some people prefer to use a GPS system and a laptop for mapping, they are usually not considered the best options. These plotters are designed to work on the water and are designed to work with the boating experience.


Because it uses both electronic charts and GPS data, it is more accurate than other systems. Likewise, it is more efficient because it pinpoints your exact location, as well as calculates direction and speed. It can also tell you how far and how much time it will take to get to your destination or next charted point. All of the information is displayed in real time, so you know exactly what you’re doing and where you’re going. Likewise, it is all updated continuously, so you have accurate information.

Many Uses

You can choose to preload your route and know where you’re going and how long it will take to get there. Likewise, you can start plotting when you get on the boat and start moving. Your Garmin marine chartplotter may allow you to store hundreds of different routes that can be used when they’re needed, as well as make changes to the predetermined path when necessary.

Easy To Use

The Garmin marine chartplotter is easy to use and required only one SD card, which can store the entire west or east coast of the US. In most cases, they come with easy-to-understand instructions and aren’t hard to learn at all.
