Buying Guide: Key Purchase Considerations For Boating
- Waterproofing and buoyancy: Look for devices designed to float or be submersible, with at least IPX7 or IPX8 protection for prolonged exposure to water and spray.
- Display readability: Choose models with bright, sunlight-legible screens and adequate size for under-hill glare conditions common on decks.
- Charting and maps: Decide between preloaded marine charts (BlueChart, Coastal charts) versus open-topo maps. Consider whether you need routable roads for land excursions or coastal navigation exclusively.
- Battery life and charging: Long-lasting batteries are essential for day-long trips. Check for compatible charging options, including drop-in cradles and USB charging.
- Satellite support: Multi-constellation compatibility (GPS, GLONASS, Beidou, Galileo, etc.) improves reliability in challenging conditions or remote areas.
- Memory and data management: Higher waypoint and route storage helps manage frequent trips, waypoints, and saved fishing spots across voyages.
- Integration features: Some models offer NMEA connectivity, inreach satellite capabilities, or compatibility with marine chartplotters for consolidated onboard data.
- Portability vs. screen: Balance compact handheld form with screen size for navigation clarity, especially when chart reading or plotting routes at a glance is required.
