Can i splice transducer cable

Actually, I would fear a junction box with connectors that just might have a little too much resistance far more than a straight ol' fashioned wire to wire field splice. Some of today's spray-on electrical sealers, connectors, shrink wrap, solvents and solder are far superior to the many layers of electrical tape I've used with great success over the years.

But, I've never cut a transducer cable primarily because the SONAR unit cost over a grand and it is not much harder to make a larger hole than to properly splice the many wires involved between the sender and unit. Appreciate the reports from those who have. Now, how sensitive the match is depends on the electronics, but I would not cut any transducer or antenna cable.

The decision is really dependent on the electronics and not the transducer. Re the transom holes: I just used the drain hole on my Outrage - and one or two too darned cold to go outside and look stainless cable clips - each held to the transom with two small stainless screws and sealant.

If you can make a decent splice, it should work. Obviously the manufacturers tell you not to, as there are more wrong ways than right ways to do it, and they don't need that warranty exposure. By the way, I agree this is a very annoying characteristic of a lot of marine electronics. Huge relatively connectors on thin cables forcing large holes to be cut.

Some of those fancy feed-through bushings they sell can help in smaller cases. For bigger connectors, another common technique is to use a clam-shell vent stuffed with silicone to hide a big hole. It also clutters up the splash well with the cable.

Regarding splicing SONAR cables, I suspect that in most instances this is possible providing the splice is well made, that is, it maintains the electrical continuity, prevents water from reaching the conductors, and does not place a physical strain on the cable. Regarding whether or not there is an impedance match between the cable, the transducer, and the SONAR device, I have some doubt.

Except in the latest and newest technology of broad band sonar devices in which special attention has been paid to handling of the SONAR transducer's impedance, the impedance of a SONAR transducer is probably not well matched to the characteristic impedance of the cable connecting it to the SONAR unit, and one should not think of the cable as acting like a transmission line conductor.

There are several reasons for this. First, the wavelengths involved are very long. Post by brambo » Sun Jul 12, am I heard you can above water line.

But know you cant below. Someone stole my off my tin boat, cut the wire right at the tranducer and left me about a 3 inch tage. I think some tweeker thought it was a TV. Anyways I tried to splice it and use a borrowed Couldnt get it to work right. I spliced, soldered, shrink tubed and then did about 10 layers of scotch coat. It failed after about 2 hours. Post by Steelheads » Sun Jul 12, am I'm sorry my friend, but you cant fix that type of cable.

Once it's damaged you need to replace it. It should work. You just have to isolate both wire so they do not touch each other.
