I have a humminbird 598cisi and a mouse/rat chewed the cable in two, five foot from the transducer. It was mounted to the trolling motor laying in my Jon Boat. Heeeelp! Thanks Junior

All of the manufacturers say that the cables can not be spliced. I've never done one, but I don't see why someone with excellent soldering skills could not put one back together. The caveat would be that there is a of of shielding that would have to be reconnected to reduce electrical interference.

The manufacturers know that it is a frequency sensitive circuit path with a continuous characteristic impedance to minimize unwanted harmonic frequency reflections and any soldering of a discontinuation requires continuous monitoring with a time domain frequency oscilloscope being swept across the desired frequency pass band.

Or you can just stick the center conductor and shielding kind of together, cover with solder and hope no one notices the unusual artifacts and loss of detail in the sonar display.

I have had a couple done over the years with no ill effects but they were done by an electronics guy.

I did a DownVu one last year with no problem. I soldered each individual wire and put shrink tubing on the individual wires. I then used liquid electrical tape and covered the shrink tubings. Then I put a larger shrink tube over the entire repair and liquid electrical tape on both ends of the shrink tubing. Been using it since with no difference in quality.

I would think that repairing as has been described above is worth a try. I'm sure there is the potential that you may be more susceptible to noise but if you try to replace the shields as good as possible you will probably be OK. I would give it a try and see if it works. It shouldn't hurt anything as long as the correct wires are connected and nothing is shorted. What have you got to loose. If it doesn't work you get a new one anyway.

Is there anyone who could do this professionally. If anyone is willing let me know, or if you know of anyone. Thanks Junior

BECAREFUL...if water gets in and shorts out the internals of you the unit...could cost you more than the transducer was to replace.

The repair would be well above three to four feet above the water line.

You can find someone at a computer or TV shop that can simply solder mend the damaged pieces back together. It will be likely good enough to still sonar detect bottom depths and see the major echos providedthe mis-reflected RF signal power does not damage the units output drivers or echo signal inputs.

A professional with RF signal and sonar electronics knowledge if found, is going to insist to use a sweep gen and TDR costing thousands of dollars and would just for the equipment rental time, charge more than the transducer is worth.

The issue with a TV shop quick repair made on an RF sensitive sonar cable is not signal 'interference' as some seem to be mis-assuming.
