How do I... get Depth Below Surface? - J-Wizzz - 2020-10-30
Looking for DBS, I'm pulling data in off old ST50 devices via NMEA 0183. I get DBT (depth below transducer) from the ST50, and I can use SK/derived-data to generate DBS... I just don't have the depth.transducerToKeel anywhere in the flows. Should I just create that? (and how?)
Thanks!

Something to test:
Maybe generate it with "Convert Signal K to NMEA0183" in the sk plugin. There it is possible to insert an Offset.
or try "Signal K to NMEA 2000" plugin, there you are able to choose the sk.input.name.
Also possible: "@signalk/calibration" plugin.
good luck and report back to us.

Sorry, these suggestions won't help with this. Conversions from SK to other formats do nothing within the SK data model. But you get high marks for being helpful!

Yeah, that was it. Exactly the value I needed, right in the FAQ. RTFM. Thank you sir!

Well, I cheated: expanded the faq to include the answer...
