Hi Gents,

Thanks for all the info. Yes, I placed a post in the boating newsgroup but
they haven't the radio tech knowledge as here.

I figured that splicing the connector would affect its abilitly to perform
100%. I do not want to damage the fishfinder head. It is 500 dollars.

Transducer and cable only about 100 dollars but the time to install it is
the kicker. It will take more than a day and I worry I would be installing a
less quality one right beside what looks to be a good quality one.For no
reason.

I was hoping someone here had done a similiar upgrade and knew how to
measure that existing tranducer with about 30 feet of cable.

Thank you all for the information, but obviously the best solution would be
to replace it. I was hoping to use existing one that may work just as
equally.

Thanks again for all the info.

Cheers

Tom, again, if you are worried about performance, which is a perfectly
reasonable thing to consider, I would recommend contacting the manufacturers of
the devices, (transducer you wish to try) and the finder for performance
specifications and potential recommendations for items that would satisfy your
needs. Having been in electronics manufacturing, (but not boating accessories) I
can tell you they should know how different transducers perform with their
finder, and vise-versa. I think this would be you best avenue to pursue. At
least it can't hurt to ask.
