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.
Frequently Asked Questions
What is the difference between a GPS and a chartplotter?
A GPS unit primarily provides location data, speed, and bearing. A chartplotter builds on this by displaying this information on a digital map or chart, offering a more comprehensive navigational view.
Do I need an internet connection for a marine GPS to work?
No, most marine GPS units and chartplotters do not require an internet connection to function. They rely on signals from GPS satellites to determine your position.
How important is screen resolution for a chartplotter?
Screen resolution is important for clarity, especially when viewing detailed charts and identifying potential hazards. Higher resolution allows for sharper images and more distinct rendering of navigational data.
Can I update the charts on my marine GPS?
Yes, most modern units allow for chart updates, either through SD cards, direct downloads, or Wi-Fi connections. Keeping your charts updated ensures you have the latest navigational information and aids.
