Upgrading to a Chirp style sonar. Any suggestions/experience in signal isolation as the wiring goes through the hull? Everything I've found on cutting and altering the transducer wiring recommends covering with splice with foil to maintain the isolating field
 around the signal. How does one do that in our applications?  Or does it matter?<br>
