The Garmin ECHOMAP UHD2 54cv is a 5-inch chartplotter with built-in sonar and navigation. It comes with the GT20-TM transducer, which supports both Garmin CHIRP Traditional Sonar and ClearVü Scanning Sonar. It also has preloaded Garmin Navionics+ mapping for U.S. coastal waters and the Great Lakes.
The color display has high-contrast palettes for use in direct sunlight and low light. A side-mounted keypad with physical buttons controls the unit. The housing is marine-grade plastic that resists UV and saltwater, and the unit is water-resistant against spray and splash. A quick-release bracket allows tool-free installation and removal.
You can switch between Traditional and ClearVü sonar modes from the menu. The unit connects wirelessly to share sonar data, waypoints and routes with compatible Garmin devices. The ActiveCaptain app handles map management and software updates, and it gives access to community-generated fishing data.
