Buying Guide: Key Considerations For Choosing A Handheld Marine GPS
- What kind of navigation data do you need? Consider whether you require coastal charts, topographic maps, or both. Models with BlueChart or Navionics data provide richer marine detail.
- How important is floating capability? If you need a unit that can float and stay visible after a drop, prioritize rugged, water-resistant, flotation-enabled designs.
- How will you use it on board? If you rely on data from other instruments, look for devices with NMEA compatibility, InReach capabilities, or chartplotter integration.
- Battery life and power options: For long trips, choose models with extended battery life or easy external power compatibility.
- Display readability: In bright sunlight, larger screens and higher contrast improve readability. Consider sunlight-readable displays and viewing angles.
- Memory and data storage: If you log many waypoints, consider devices with larger internal memory and expandable storage.
- Durability features: IP ratings, rubberized housings, and shock resistance matter for rough seas and outdoor environments.
FAQ
- Which handheld GPS is best for saltwater navigation?
– Devices with coastal charts (BlueChart, Navionics) and floating designs are ideal for saltwater use, such as the Garmin GPSMAP 79sc or 79s. - Do handheld GPS units float?
– Some models are designed to float or are explicitly marketed as floating, which helps recover them if dropped overboard. - What is SAILASSIST and who benefits?
– SAILASSIST features aid sailors with starting lines, tack guidance, and other sailing-specific data—useful for racing or cruising. - Is multi-GNSS important?
– Yes. Multi-GNSS (GPS, GLONASS, Beidou, Galileo, etc.) improves tracking accuracy in challenging environments like urban canyons or forests near water. - Can these devices connect to chartplotters or InReach?
– Some models support data streaming from chartplotters and satellite communication like InReach for remote areas.
