Re: Can I splice it?

If you can splice coaxial cable, sure. If not, find a twidget (electronics tech) to do it for you.

Good luck. :)

Can you? ..... sure

The proper way (short of replacing the cable) is to put BNC connectors on each end and couple them together with a BNC coupler. Heat shrink the connection.

Plan B: Hopefully you have a little slack. Cut the cable on each side where the damage is so you have 2 clean cut ends. Strip only the outer insulation off both ends about an inch.Peel back the shield and twist them to form a manageable piece of wire. Now cut a little if the inner insulation to expose the center conductor. Tin both center conductors and the shields with solder. Put a 3" piece of shrink tube down one of the cables. Solder the center conductors together an insulate the connection with a small piece of electrical tape. solder the shields together and pull the shrink tube over the whole repair and shrink it.

Go boating.

just like stealing cable tv. for years my neighbor and i used the same Cable hook up, just buried a cable from one house to the other. split the bill.

With over 9000 posts, it is conceivable that you will tell more than we want to know. You jumped the shark with the cable tv deal. :D

I think you’ll find anywhere from 3-10 individual wires (24-28 ga) running inside that cable depending on the functionally of your transducer.

Some manufacturers make “break out” boxes to make splices or you can do it the old fashion way and solder each and every wire you need in the bundle back together again. It’s not hard just time consuming if you need the full compliment of wires in the cable.

All the fishfinders I have owned have not had coaxial cables in them...yours may be different. If you just have plain wires, there is no problem splicing them.

I agree with Bruce, but have never cut into one. The transducer operates on 200kHz or less, considered to be a very low frequency, in the signal transmission world.

Coaxial cables and waveguides are for transporting high frequencies where transport losses are very high with conventional systems. CB radio is a good starting point for the average consumer for coax. They use around 27 MHz, about 100 x what your depthfinder runs.

Added note. It is possibly just a shielded cable and not controlled impedance as coax is. The shield is to reduce interference on your display caused by other electronic noise sources in your boat.

So, on this type cable, splicing is just a matter of connecting (and insulating from each other) the conductors with adequate waterproofing to prevent corrosion and water intrusion.

Re: Can I splice it?

Generally speaking, transducer cable is 2 cores screened. Triducers, which are a depth transducer, a water temperature sensor and a speed paddle-wheel, usually have the 2 transducer cores, screened and 2 wires for each other function, also screened. If you have a good soldering iron and have done screened cables before, splice to you heart's content. :D
