I just got a new Furuno 1824C/NT system and also purchased an M260 transducer. The only drawback to this transducer is that I now have no surface temp. sensor. I have a couple of old lowrance transducers that have built in temp sensors and i was wondering if there is a way to to use the output of the temp sensor from one of these transducers to input temp data into the Furuno display???? I figured if i can utilize the old transducer as a temp sensor only I could save me some cabbage.......
