Transducer Cable
"Bruce in Alaska" wrote in message ... In article , Michael Porter wrote: Gotta be very careful though -- with analog transducers, the length of the cable is figured into the delay time which is what the souonder uses to work out the depth. Might have to recalibrate. Michael Porter There is NO difference between how a digital and analog Depthsounder determines depth. It is all done by timing the ultrasonic transmit pulse leaving the transmitter, with the reflected received pulse in the receiver. The difference is how the information is displayed to the human operator. The length of the transducer cable is irrelevent to that timing, as the delay is insignificant when compared to the speed of ultrasonic sound in water, Fresh or Salt. Transducer cables certainly can be spliced. It is a relativly easy process and with the frequencies involved usually less than 400Khz, any introduction of extra capacitance to the transducer cable will usually not cause much change in the Tx/Rx tuning of the sounder circuits themselves. I am sure that Oldtimers, like Lynn, and Larry, have done this MANY times, just to save some boater from having to haul the vessel just because he crushed the tranducer cable by setting an engine block, or battery on it, while futzing around in the bilge.
