Garmin GPSMAP 743 7″ High-Resolution Chartplotter

The Garmin GPSMAP 743 is a compact 7-inch chartplotter for small center consoles, bay boats, flats skiffs, and cruising sailboats where dash space is limited. It brings a sharp IPS touchscreen, 10Hz GPS receiver, Garmin network connections, and a worldwide Navionics+ basemap into a size that can work as a main display on a small boat or a second station on a larger one.

The 1024 x 600 screen is noticeably easier to read than older 800 x 480 displays when chart labels, waypoints, and data boxes are close together. It supports Garmin Marine Network, NMEA 2000, NMEA 0183, J1939, WiFi, Bluetooth, and ANT+, so it can grow with the boat. It is not a standalone fishfinder; the supplied information does not list built-in sonar or a transducer, so sonar must be handled through compatible external equipment.

Who Is This For?

This compact Garmin chartplotter suits 16- to 26-foot coastal boats, flats skiffs, sailboats, and small center consoles. It is not ideal for a helm that needs large split-screen pages or a buyer needing built-in sonar and a bundled transducer.

Warranty & Support

The supplied specifications do not state a warranty term. Confirm current Garmin warranty coverage before purchase.

The GPSMAP 743 is the compact option when a small helm still needs a capable connected chartplotter. It gives better screen detail than basic 7-inch units, but the trade-off is obvious when the boat gets busy: there is less room for chart, radar, and other pages. Choose it for a compact Garmin network, not a large split-screen helm.
