Garmin GPS 73 Handheld Navigator — SailAssist, 2.6-inch Display

Meet the Garmin GPS 73, a compact, floatable handheld navigator designed for power boats, sailboats, and small watercraft that don’t have a chart plotter. Its high-sensitivity GPS and easy-to-read display help you mark routes and return to them with confidence, even in challenging conditions. Sunrise, sunset, and other marine data add practical context for planning a day on the water, while NMEA 0183 support keeps it compatible with other instruments.

Smart sailing with SailAssist

The SailAssist feature adds sailing-focused tools to navigation, helping you plan and execute maneuvers more smoothly. Expect a virtual starting line for race setup, a heading line to hold a course, countdown timers for timed tasks, speed history to review performance, and tack assist to support strategic course changes.

• Virtual starting line for precise race timing
• Heading line to maintain your chosen course
• Countdown timers for timed maneuvers
• Speed history to assess pace over time
• Tack assist to guide sail changes

These features are designed to enhance planning and on-water decisions without replacing your judgment. They offer possibilities for smoother handling and better situational awareness on deck.

Long-lasting reliability on the water

With 18+ hours of operation on two AA batteries, the GPS 73 supports long days on the water. A built-in backlight makes reading the high-contrast display easy in bright sun or low-light conditions, while intuitive, dedicated buttons keep operation straightforward.

• 18+ hours of battery life under typical use
• Backlit, high-contrast display for day and night reading
• Floating design for quick recovery after a splash

Plan, save, and return with confidence

The device stores up to 1,000 waypoints and 100 tracks, letting you map favorite harbors, anchorage spots, buoys, and routes. Plan trips with route planning features, then navigate back via direct lines or saved tracks. Additional data such as sunrise/sunset times, estimated time of arrival, and marine data support practical, on-water decision making.

• 1,000 waypoints and 100 tracks for flexible planning
• Route planning and easy back-navigation
• Sunrise/sunset times and estimated arrival data

Practical on-the-water use

Whether you pilot a powerboat, sailboat, or small watercraft without a chart plotter, the GPS 73 serves as a reliable navigation backup and safety tool. It floats, offers man overboard (MOB) functionality and marine alarms (off course, anchor drag, etc.), and provides marine data to support situational awareness on deck.
