Depth finder replacement
I have a 2001 3000SCR and the factory depth finder no longer works, all it shows is the error code "SL". My mechanic looked at it and he took a different transducer, plugged in the wires attached to the display, and hung it over the side of the boat in the water. He got the same error message and then told me that it looks like the display is the problem, not the transducer.
This made me wonder, if the transducer IS ok, will it work with other depth finders?
I can find cheap depth finders for just over $100 that come with transom mount sensors and I didn't know if I could get one of those, and just use the existing wiring and through-hull transducer with the newer display? My other thought is that if the transducer is already 12 years old, and they wear out, would this even be worth it? Either way, I was still curious...are transducers universal, or specific to the manufacturers displays?
