Buying Guide for Boat GPS Devices
Choosing the best GPS for boating requires consideration of several important factors to ensure performance, safety, and ease of use while on water.
Chartplotter vs. Handheld GPS
- Chartplotters like the Simrad Cruise 5 are installed on your vessel, offering large screens and detailed navigational charts for continuous display during outings.
- Handheld GPS units such as the Garmin GPSMAP 79 series are portable, waterproof, and useful for navigation as well as backup safety tools.
Map and Chart Coverage
Consider whether preloaded charts cover your boating area. Coastal charts such as C-MAP or Garmin BlueChart provide bathymetric data, hazards, and navigational aids critical for safe boating. Worldwide basemaps offer general location awareness but less detailed coastal data.
Durability and Water Resistance
Marine GPS devices should be rated for water resistance (preferably IPX6 or higher) and rugged enough to withstand marine conditions including impact and corrosion. Floating capability, found in handhelds like Garmin 79sc, is a valuable safety feature if the device falls overboard.
Display and Interface
A clear, sunlight-readable color display improves readability in bright outdoor conditions. Intuitive controls and touchscreen or rotary dial navigation ensure ease of use while operating your boat.
Speed Measurement
Speedometers with GPS integration, such as those from MAIMEIMI, provide accurate speed and distance calculations without needing a paddlewheel sensor. This is advantageous for boats without traditional speed sensors.
Emergency Features
Devices like the ACR ResQLink 400 provide emergency SOS beacon functionality, essential for distress signaling in remote marine environments. Such features can save lives by expediting search and rescue response times.
Battery Life and Power Source
Ensure your GPS device has sufficient battery life for your typical outings or is compatible with your boat’s power supply for extended use. Charts and active tracking can consume more power, so plan accordingly.
Additional Features
- Multiple satellite system support for improved accuracy and coverage
- Storage for extensive waypoints, routes, and tracks
- Compatibility with external sensors or autopilot systems
Assess your boating needs carefully to select a GPS that balances navigation accuracy, durability, ease of use, and safety features to ensure reliable performance on the water.
