I used the Airmar DST800 NMEA2000 version, plastic; it was a direct drop-in replacement for existing depth-sensor (located in bilge outside the FWD head).
Downside: paddle wheel = cleaning, and exposed location.
Upside: no extra hole for speed+depth; plus temp. Was incrementally rolling out the N2K backbone (which presently ends at the sensor). Next: will run the backbone up the mast to terminate at the Wind Sensor, which I will do in 3 wks time, when I pull the masts to replace the standing rigging (ACMO).
