Compatibility
Compatible with ECHOMAP UHD2 touchscreen sv chartplotters, including the 74sv and 94sv coastal packages. Also supported by compatible GPSMAP 8400/8600 xsv models with the required software. Confirm your exact chartplotter and connector before ordering; this is not a universal transducer.
The 94sv coastal package offered by Lost Winds already includes a GT56 transducer. The 74sv package includes a GT54; a separate GT56 is an optional upgrade rather than a required addition.
Included
GT56UHD-TM transducer, transom mount, mounting hardware and documentation. A chartplotter is not included. Part number: 010-13073-00.
