No detail as to whether they are really lower power. Practically impossible as you will need someone to do A-B testing with it and the Ray drive on the same boat and sailing conditions. Looking at the graphs suggests they are on to something, but that is just a few pictures.

I figure they can't be worse than the Ray's. I don't mind being another date point. I have to stop researching and buy something at some point. Finally, I still reserve the right to change my mind at any point.

On the B&G (and Simrad, same unit) NAC3 computer there are a couple of options for rudder sensor. The latest Simrad is an NMEA 2000 unit that plugs into the backbone. However the NAC3 (and 2) has an option to connect a sensor directly to the computer board that I'm guessing might be compatible with the Garmin/Jefa drive sensor.
