Thread: spliceing transducer cable

I never had a problem, done it several times, eaven use the heat shrink shrink, as far as the shield, I just cut the rubber back far enough to get more shield than I needed and just overlapped the shield and no problems.

It is very possible that the lower frequencies that these units operate at, will not result in a significant impedance mismatch and not cause a significant problem.

Like Cane Pole said... The length of the wire on a depth finder has nothing to do with the return.

I am a towboat pilot & we use depth finders with portable tranducers to place on the head of our tows. The extention cords are cut in 200' lengths. We may have out as little as 200' or as much as 1600' depending on the size of the tow.

Never have a problem as long as you take care of your cords. We splice the wires all the time.

I spliced a HB SI cable for DonG and it works fine.

Thats why we love ya CP you think of everything.

So you dont have to solder the shield? Thanks Beagle

I would solder the shield or wrap it with aluminum foil under the tape or shrink tube. Unfortunately, most shields today are no copper and will be hard to solder.

You best solder the shield. It is signal ground in most cases. I put a "how to" on here couple years back. I will try to retrieve it. Might be in the archives.

I know everyone has told you to solder it and they are right. I tried it without soldering and it did not work. I re-did mine by soldering and heatshrink just like everyone is saying and it has been fine for a couple years now.
