Transducer cable

[Wightdiver]

Does the transducer cable need to be a single length or can it be extended with a joint. If so any suggestions?

Thanks

Andy

Surley someone out there knows the answer?

[Nasher]

Some will say don't join it, however, as long as the joint is well performed and some effort is put into replacing the shielding and ensuring it's waterproof it will be OK.

In other words, it's all about the quality of the join.

Is this for a fishfinder/sonar type transducer?

If so, I think the answer is "it's not recommended, but it can be done if it is done well."

Yes it is the fishfinder type transducer. It is on a project boat that I have just bought and want to remove it before stripping out the console.

I will give it a go as I do not have a lot to lose.

Thanks for your reply.

Call the manufacturer. I know Teleflex's transducer cable lengths were not able to be shortened or lengthened as per the manufacturer. Has to do with the resistance of the cable, which is partially determined by the length.

Or since you have "nothing to lose" GO FOR IT!

Thanks to all.

I found this via Google.

I think the risks of a poor repair or of shortening the cable are reduced performance, or reflecting lots of stuff back to the unit itself and damaging it. Those pulses are really short and a step change in impedance at a poor repair could reflect lots of stuff back (a much bigger signal than would be returned from a signal that has gone out, to the seabed and back up again, through the transducer and down the wire) or stop any signal reaching the transducer.

My Navman fishfinder was fitted to another boat before it was fitted to mine, the cable had to be cut to remove it, all soldered up and working fine, no problems at all

Sometimes I wish I still had my Navman
