How to Choose a GPS Chartplotter
Choosing a marine GPS chartplotter doesn’t have to be a hassle. There are a few key factors you should consider when choosing your system, such as:
Mounting Method – Most marine GPS chartplotters are flush or non-flush in your boat’s dash. Some come with bail mounts, some with suction cups, and others have permanent mounting hardware.
Screen Size – The overall size of the unit and display will determine your viewing area. Generally, larger screens provide more detailed images and a better overall user experience.
Advanced Features – Many GPS chartplotters, including handheld marine GPS, now have advanced features such as fish finders, radar, barometric altimeter, and AIS (Automatic Identification System).
User Interface – Choosing a system with an intuitive, easy-to-use interface is essential. This will make it easier for you to use the system without learning complex commands or menus.
Navigation Accuracy – Make sure you choose a GPS chartplotter with the highest level of accuracy. A preferred GPS system should get you from point A to point B without glitches or errors and within a few feet of perfect.
Connectivity – The ability to connect your chart plotter to other devices and systems is essential, such as your smartphone or tablet, a VHF radio, autopilot and engine data, fuel management systems, and more.
Weighing all these factors will help you find the best GPS chartplotter. Now let’s dive into the 12 BEST GPS chartplotter systems on the market today!
