I stand corrected.
I was thinking about the Northstar speed log on my boat, which contains the temperature sensor. My Garmin plotter/sounder also shows temperature (not reliably, since the transducer is on the inside of the hull), so on my Garmin the thermister is in the depth transducer. Not sure how Raymarine does it - but I'd guess the thermister is on the transducer for whichever display the data appears on.

I thought the temp was part of the depth transducer not the paddle / speed? I will have to re -read this manual.
