Transducer cables- Rejoining

[Iron Dials]

A couple of months ago I bought a Lowrance HDS 7.
Previously there was a ( very old) Garmin telling me how lost I was.
So new transducer required.
There are a few points where it would be much easier to run a cable without a big plug on the end.
So my question is (and the voices in my head are saying NO!) is it possible/ difficult to reliably rejoin a cable if I cut it to make life easy?

I done it on my Garmin and it worked perfect

It can be done - I'd work long hours to avoid it tho!

Nice video instruction.
I have spliced transducer cables many times.
One thing that was not mentioned in the video. After you cut the outside jacket only cut one wire at a time. I was instructed to do it this way many years ago by a navy sonar specialist. So, that is how I have done it and I have never had a problem.

Yes, you can do it without a problem. Just solder each wire carefully and use fine shrink tubing over it and be sure to wrap the shielding where it's necessary. Seal the whole joint area with glue lined shrink tube or cover it with evostick and shrink normal shrink tube. If you do the latter, heat from the middle of the joint outward to expel any air and solvent vapour.
When you've opened the cable, shorten the cores a little but leave the shielding long so you have a bit to play with when rewrapping.

We joint all our underwater cables with potting compound from RS supplies for a total watertight seal you can buy little moulds too for a professional job not expensive

Also done it several times. Soldier and heatshrink with the glue in it. Cut it in an appropriate place and it won’t end up under water.

Thanks very much folks.

My jury is still out, additional deck gland costs €25 but that's another (avoidable) hole in the boat.
