Author Topic:   Fabricating Transducer Extension Cable

I've been trying to get an extension cable for the transom-mount, dual-frequency SONAR transducer for my Lowrance LCX-25C fishfinder/GPS. This era of Lowrance cabling uses blue/gray connectors at each end.

Both LEI Extras and a retailer indicate that the cable has been on back order for more than a month and a half, and isn't due in for another month at the soonest. My thought then turned to fabricating my own.

Is there a standard type of cable used for transducers? Are the connectors fairly generic? I realize that I'll have to pay particular attention to making any junctions resilient to the elements.

Or, is there a ready-made cable from another manufacturer that would work for this?

Frank, get yourself a Newark Electronics catalog, and
start leafing through. There are 200-300 pages of connectors.

Allied Electronics is another name, but I think the Newark
is a bit more complete.

This is the distribution/tech support arm of the mfr of your transducer - call them:

Thanks, those both sound like good ideas.

I found, incidentally, that I have an old, defective transducer with 20 feet of cable that's likely just fine. So if I can pick up one compatible connector I can probably make the extension cable I want with minimal fuss.
