Buying Guide: How to Choose the Right Marine GPS With Maps
What type of device fits your needs? Decide between helm-mounted chartplotters for on-bridge navigation and handhelds for backup or remote access. Consider screen size, sonar capabilities, chart coverage, and ease of data sharing across compatible devices.
- Navigation needs: If you require radar integration and wide-area mapping, prioritize multifunction helm units like the Simrad GO9 XSE.
- Chart coverage: Look for inclusive map cards or built-in charts that cover your typical routes, including inland, coastal, and bathymetric detail.
- Sonar functions: Dual or multi-CHIRP, Down Imaging, and ClearVü help identify structure and targets; choose based on desired target detail.
- Display size and visibility: Larger screens aid in quick interpretation on the water; ensure readability under bright sun.
- Power and mounting: Helm units require appropriate power connections and transducers; handhelds offer portability but rely on battery life and floatation.
Frequently Asked Questions
- What is CHIRP sonar and why does it matter? CHIRP sonar provides higher resolution returns, improving target separation and bottom detail for clearer fish arches and structure.
- Do I need a transducer with my chartplotter? Most helm-mounted chartplotters require a transducer for sonar; some bundles include one, others do not, so check configuration.
- Can handheld GPS devices replace a chartplotter? Handhelds are best as backups or for on-deck use; helm-mounted units offer more display space and integrated features.
- What maps should I look for? Prefer devices with vector charts, high-resolution bathymetry, and compatibility with strong chart providers like C-MAP, Navionics, and Garmin LakeMaster.
- Is wireless sharing important? Wi-Fi or network features allow data sharing between compatible units, useful for multi-display setups on larger boats.
- Should I prioritize screen size or features? Balance display size with features such as CHIRP sonar, radar readiness, and map coverage to fit your boat and crew needs.
