Transducer Substitution

[tytower]

I have a Navman 4100sx fishfinder but the transducer was cut and left on the old boat so now I have the electronics part with cabling but no transducer .

Does anyone know if an aftermarket transducer or replacement is available that will work ?
I note that Navman has become Northstar and my model is no longer listed so I suppose its been made obsolete by the new models.

Emails to their web site in NZ have just been ignored.

hi,
Do you have any technical details of the sounder, frequency and power would be a start in suggesting an alternative.
EDIT:
I see from the web its 200kHz, about 50 to 80Watts

I did see a lot of sources of second hand parts on the web.
