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.

Maybe the problem people are having is with your use of the word
"splice". That implies that you are cutting the cable. But on
rereading your post I think you are just asking if the existing
transducer is compatible with the new head. I assume they have
connectors at the head unit and at the transducer, right? Do they use
the same connectors on both the new and the old systems?

I certainly don't know anything about these transducers, but I am sure
there is more to it than just the frequency of the fish finder. There
is also impedance and power level. What do you know about the two
systems? Does the manual tell you much about it?

As others have suggested, you might want to contact Lowrance to find out
what they say about compatibility. It is unlikely they will tell you
much that you can bank on since they won't want to assume any liability.
But asking won't hurt. It may turn out that the transducers are a
common denominator in the industry and there is little incompatibility
like other electronics.
