The 10 Best Marine GPS

This review has been updated 27 times since it was first published in June of 2015. Don’t take your boat out on any serious excursion without a chartplotter qualified for the job. Many newer models support automatic waypoint generation and connect with extremely advanced sonar, GPS, and even GLONASS networks to keep you safe and monitor your ship’s systems. These make marine navigation so easy, you’ll never have trouble finding that favorite dive spot or fishing hole again.
