Buying Guide
What should you consider when choosing a gps plotter for a boat?
- Display size and readability: Bigger screens help in bright sunlight and multitasking, but may require more cockpit space.
- Sonar capabilities: CHIRP, DownScan, SideVü, and Dual Spectrum options vary by model; choose based on how you fish and where you operate.
- Mapping and charts: Pre-loaded maps vs. upgrade options; check coverage for your waters (coastal, inland, lakes, tides).
- Combination features: Some models add radar, Wi-Fi sharing, and multi-display network functionality—assess whether you need an all-in-one system.
- Transducer compatibility: Ensure the transducer type (83/200 kHz, DownScan, etc.) fits your hull and mounting plan.
- Boat size and power draw: Larger displays and networked units can affect power usage and mounting space; plan accordingly.
FAQ
- What is CHIRP sonar? CHIRP sends a range of frequencies to provide detailed, clearer images of fish and structures.
- Do these plotters support radar? Some models do, including multi-function displays like the Simrad GO9 XSE; check the exact model features.
- Can I share charts between devices? Yes, certain Garmin chartplotters offer networked sharing when compatible.
