The Garmin ECHOMAP UHD2 73sv is a 7-inch touchscreen chartplotter and fishfinder built for anglers who run inland lakes and rivers. This is the no-transducer configuration (MPN 010-02684-00), which lets a buyer pair the unit with the exact sonar that fits the boat and budget rather than paying for a bundled sensor they may not want. It ships with Garmin Navionics+ U.S. inland mapping covering more than 18,000 lakes with detailed contours. For boaters who already own a compatible sonar or plan to buy one separately, this saves money up front. Browse our chartplotter and fishfinder selection for related units.
The 73sv runs a 7-inch diagonal WVGA sunlight-readable touchscreen at 800 x 480 pixels, with a usable display area of 6.1 by 3.4 inches. The housing is polycarbonate plastic rated to IPX7, so brief submersion won't kill it, and the unit operates from -4°F to 131°F. It accepts 9 to 18V DC input and supports optional CHIRP, ClearVü, and SideVü transducers, plus Wi-Fi and NMEA 2000 networking for connecting to compatible sensors and accessories. Onboard storage handles up to a 32 GB microSD card. The waypoint memory holds 5,000 marks, 100 routes, and 50 saved tracks with 50,000 track points. Mounting is handled with the included bail mount or a flush-mount setup. At 2.2 pounds, it fits tight console spaces on smaller boats.
This unit makes sense for the angler who wants Garmin charting and sonar capability but already has a transducer or wants to choose one to match a specific fishing style. Run it as a standalone navigation and mapping display, or wire in a SideVü or ClearVü transducer later to add detailed bottom imaging. The NMEA 2000 port opens the door to engine data, sensors, and other networked gear as the rig grows. When you're ready to complete the build, see our transom-mount transducers and NMEA 2000 sensors to round out the system.
No. This configuration (MPN 010-02684-00) ships without a transducer. It supports optional CHIRP, ClearVü, and SideVü transducers, so you can add the sonar that matches your fishing style. If you already own a compatible Garmin transducer, this version saves you the cost of a bundled sensor.
It comes with Garmin Navionics+ U.S. inland mapping, covering more than 18,000 U.S. lakes with detailed contours. You can expand or update coverage using the microSD card slot, which accepts cards up to 32 GB.

Yes. It includes NMEA 2000 networking and Wi-Fi, allowing it to share data with compatible sensors, engine gauges, and other networked gear. This lets you build out a larger system over time as you add transducers and accessories.
The display measures 7 inches on the diagonal, with a usable viewing area of 6.1 by 3.4 inches. It's a WVGA sunlight-readable touchscreen at 800 x 480 pixels, designed to stay legible in direct light on the water.
