Default Transducer HELP!!!!

hey guys, im new to the forums, but i have a question

i just bought a boat that had a radarsonics through hull transducer.

well i bought a garmin 440sx, and it didnt come with a transducer, i was wondering if anyone could tell me what wires i can splice to each other to make the transducer work.

I Know your not suppose to cut the wires, but i want to make this work

thanks for your help

I'm not sure at all. Check on Garmins website. They may have a compatibility chart? If not their tech help is considered real good.

Not to be the bearer of bad news, but it probably won't work. You are going to want to find any labels on the ducer cable and copy them down and contact radarsonics and find out what your transducer actually is frequency wise. Most radarsonics transducers that I have seen have been single frequency, not dual, and you also run the risk of impedance problems even if successfully/correctly spliced. Any idea what sounder was there to begin with? I normally only saw radarsonics ducers with Sitex/Koden sounders and old MarineTeks.
