The Garmin ECHOMAP™ UHD2 74sv (Without Transducer) is a powerful 7-inch chartplotter that balances advanced sonar processing with industry-leading cartography. This unit is designed for mariners who already have a compatible 12-pin transducer or require a specific mounting style (such as through-hull) to suit their vessel.
NMEA 2000® Compatibility: Connect to a wide range of onboard electronics, including autopilots, digital switching, FUSION-Link™ audio systems, and engine sensors.
Wireless Data Sharing: Built-in Wi-Fi® allows for the wireless transfer of sonar data, waypoints, and routes between compatible ECHOMAP UHD2 units.
