I believe I've sent that through a couple times
in the past, but can send NMEA logs from Furuno
and Garmin depth sounders again if it is wanted.

Note that while technically related to elevation,
the "depth below sounder" isn't part of any 3D GPS
solution, will have different sampling and error
characteristics, and the two shouldn't interact
automatically; it's ancillary data like the almost
always co-available transducer temperature NMEA
sentence.
