Garmin ECHOMAP UHD2 73sv Chartplotter/Fishfinder Combo w/US Inland Maps & GT54UHD-TM

The Garmin ECHOMAP UHD2 73sv is a compact chartplotter/fishfinder combo for inland fishing, small boats, and trailerable craft. The package includes a GT54UHD-TM transom-mount transducer and Garmin Navionics+ US Inland charts, so the main sonar hardware is included rather than left for a separate purchase. Its 7-inch 800 x 480 touchscreen with keyed assist keeps operation simple, though it offers less display space than Garmin’s 12-inch GPSMAP units.

Key Features

- 7-inch touchscreen with keyed assist → Combines touch operation with physical button support for easier control on a moving boat.
- 800 x 480 resolution → Keeps the display compact and readable for basic charting and sonar views, but provides less detail than Full HD screens.
- GT54UHD-TM transom-mount transducer included → Supplies the transducer needed to use the included sonar features without buying one separately.
- High-Wide CHIRP, UHD ClearVü, and UHD SideVü sonar support → Provides traditional fishfinding plus downward and side-looking views for examining structure.
- Built-in WiFi → Supports wireless data sharing within the capabilities of the Garmin system.

Who Is This For?

This bundle is built for small fishing boats, inland anglers, jon boats, bass boats, and trailerable craft that need charting and sonar in one compact package. The included transom-mount transducer makes it a practical choice for a new installation.

It is not the right choice for a large offshore helm that needs a 12-inch display, or for a buyer who requires the wider network expansion listed for the GPSMAP 8612xsv. The preloaded chart coverage is US Inland rather than the coastal and inland US/Canada coverage listed for the larger Garmin model.

Compatibility

Confirmed components include the Garmin GT54UHD-TM transom-mount transducer, Garmin Navionics+ US Inland charts, and built-in WiFi. The supplied specifications do not confirm NMEA 2000, NMEA 0183, autopilot, or third-party chartplotter compatibility. No specific incompatible system was provided; verify Garmin accessory and network requirements before adding this unit to an existing installation.

Warranty & Support

Garmin provides a 1-year limited warranty. The supplied specifications do not state warranty exclusions or service procedures.

The ECHOMAP UHD2 73sv is the practical value choice in this group because it includes both the GT54UHD-TM transducer and US Inland charts. That makes it easier to install than the transducer-free Garmin GPSMAP 8612xsv or Raymarine units. The trade-off is the smaller 7-inch 800 x 480 screen, limited chart region, and WiFi-only networking listed in the specifications. Choose it for a compact inland fishing setup, not for a large offshore electronics network.
