How to Choose the Best Marine GPS Units & Chartplotters
Screen Size and Visibility
Consider the size of the display based on your vessel and how you'll use it. Larger screens are easier to read from a distance and provide more detailed chart views, but they also take up more space. Ensure the display is sunlight-readable and has good anti-glare properties for use in bright conditions.
Features and Functionality
Determine the essential features for your needs. Basic GPS units offer navigation and tracking, while chartplotters integrate chart display, sonar, radar, and autopilot controls. Think about whether you need advanced features like weather overlays, fishfinding capabilities, or NMEA 2000 connectivity for integrating with other marine electronics.
Ease of Use and Interface
A user-friendly interface is crucial, especially when operating under pressure. Look for intuitive menus, responsive touchscreens, or well-placed physical buttons. Test the interface if possible or read reviews that specifically mention usability. A steep learning curve can detract from your time on the water.
