Abstract

A transducer and electrical cable combination for use, preferably, in a trolling motor. The electrical cable includes an outer shield connected to the chassis ground of the trolling motor; an inner shield connected to the signal ground of the transducer; and a pair of signal carrying conductors comprising a twisted pair.

Claims

1. A transducer and electrical cable combination, comprising:

a transducer having a transducer output; and

an electrical cable having;

a twisted pair of conductors connected to said transducer output;

an inner conductive shield surrounding said twisted pair of conductors;

a dielectric jacket surrounding said inner conductive shield;

an outer conductive shield surrounding said dielectric jacket; and

wherein said transducer output is connected to said twisted pair at a first end of said electrical cable and a receiver having a receiver ground is connected to said twisted pair at a second end of said electrical cable and said inner conductive shield is connected to said receiver ground.

2. The combination of claim 1 wherein said dielectric jacket is a first dielectric jacket and further comprising a second dielectric jacket surrounding said outer conductive shield.

3. The combination of claim 1 wherein said receiver is mounted in a water craft having a trolling motor connected to a source of DC electrical power with a positive lead and a negative lead and said outer conductive shield is connected to a negative lead ground.
