The Airmar B75H transducer should not be turned on when it is not in the water to avoid over heating. My question is : When the transducer is disabled using the Garmin 8616 MFD, the sonar definitely stops but does the temp sensor stop working also.
Mine does not send temp data but I was sure it did in the past. The transduced is known for temp sensor failures but I am hoping that is not the case.
