So, having some issues with my DSM and MFD. I have a C-80 and a DSM 300. Has been determined they need to be sent in. But..in trouble shooting, noticed I have 2 transducers in the hull.

The DSM is on an accessory switch on the dash, though I still get a correct depth reading with the DSM off.

My main question is why 2 transducers? One says 20 degree tilt on it. Does one go directly to the C-80, and the other to the DSM?

Pretty sure this was done stock, and not after the fact. Any insight anyone?

Thanks!

One is probably depth and temp. The other is the fish finder transducer, which can also do depth. I've got the depth/temp sensor in my 348, but the temp went bananas last winter. Depth still works and I don't need the temp bad enough to pull the boat to replace it.

OK, gotcha. Yeah, my temp just started going haywire. Reading 30 degrees in the Potomac right now haha. Guess I will have it changed out next time we get pulled, probably not this winter, but next winter.

Yup, mine started reading 130F over the previous winter. Then various randomness, like 17F this Spring. Now it just doesn't respond at all. I don't really miss it, but I will replace it the next time we pull the boat.
