Buying Guide – How to Choose the Best GPS for Sailing

Selecting the right GPS for Sailing depends on your typical sailing environment, device durability needs, and chart requirements. Use the following factors to narrow down your options.

Display Quality and Size

A clear readable display is vital for checking your position and charts under bright sunlight. Larger screens improve detail, but handhelds should remain compact for portability. Ensure the resolution supports legible text and symbols at a glance.

Look for sunlight readable screens with high brightness and anti glare coatings to maintain clarity while underway.

Satellite Accuracy and Support

Multi-GNSS support including GPS GLONASS Galileo and Beidou enhances tracking reliability especially near coastlines or in valleys. Devices with multi-band technology offer superior accuracy in challenging signal environments.

Choose models that support multiple constellations for global coverage and consistent positioning in varied marine settings.

Chart Coverage and Data Storage

Preloaded coastal charts save time and cost compared to buying them separately. Check if maps cover your sailing regions. Also consider memory capacity for waypoints routes and tracks if you plan to store extensive trip data.

Ensure the device supports SD cards if you need to expand storage for multiple regions or detailed mapping.

Durability and Water Resistance

Marine environments demand rugged devices rated for moisture and splash resistance. Devices that float or are waterproof to IPX7 standards reduce risk if dropped overboard. Look for scratch resistant glass for lasting clarity.

Prioritize units that float and meet high IP ratings to maintain functionality in rough or wet conditions.

Battery Life and Power Source
