Hi

I replaced my Eagle Supra ID fishfinder head with a new Lowrance Elite 5
(came with new transducer). The present transducer is the round style
glued to the bottom hull (through hull).

Is there a way to test the transducer to see if it is 200khz compatible
for the new Elite 5? Can I simply splice it myself or is there a reason
why I shouldn't. I have spliced coax many times.

But I really don't want to replace that cable up to the flybridge
through a lot of fishing and pulling. I am wondering if I can use the
old transducer and cable (extension & old transducer with 10ft wire). I
think the extension is 15 feet or so.

Any ideas? I am hoping I can simply splice the plug of the old
transducer wire to the new head.

Thanks for any ideas

Cheers

Coax can NEVER be spliced without causing a huge impedance mismatch at
the point of the splice. This is not 60hz or DC. But any ham with even
a minor bit of technical knowledge should understand this.

The only way you can effectively "splice" coax is with connectors, i.e.
two males and a double female. That will provide a splice with minimum
loss and impedance bump.

You would have to look at the specs for your new transducer to see if
its compatible or not. And I would recommend just replacing the coax;
you may not want to, but it's the best way.
