This easy-to-use handheld is the perfect navigational solution for boats, sailboats or small watercraft that do not have a chart plotter. It’s also ideal as an important emergency navigation backup for all vessels. Its high-sensitivity GPS marks and stores 1,000 waypoints and 100 tracks so you can navigate right back to them. Use on land or water — it floats! Features SailAssist, including virtual starting line, heading line, countdown timers and tack assist.
