When powered up the transducer will emit "pulses". You can feel them and hear them if you are (very) close to the transducer. I have the us2 on my minnkota and can feel and hear the ducer working. As stated by Hays...make sure you have power. If power is not the problem then I would suggest you have a faulty transducer.
Sacred Heart of Mary, pray for us now, and at the hour of our death. AMEN
For those who believe, no explanation is necessary....for those who don't, no explanation is possible
For the sake of his sorrowful Passion, have mercy on us and the whole world
