OK here's the situation. I currently have the following connected to a Garmin Fishfinder 240
1 x Garmin Transom mount transducer (Depth & Temp)
1 x Garmin speed wheel on the transom
I have just bought a Garmin IN HULL depth transducer because I was getting turbulance from the Duo-Props: https://buy.garmin.com/shop/shop.do?pID=680
Now, I'm pretty certain I can just un-plug the transom mount transducer and plug in the in-hull, no problem. However, I would love to keep the transom mount transducer as a temp probe (It'll be staying on the hull anyhow).
Here's the question, is the Garmin cabling of the transducers simply normal cables wrapped in the black shroud? Would it be possible to just splice the in-hull transducer cables into the transom mount transducer cables? ie. Have temp reading coming from transom mount transducer and have the depth coming from the in-hull transducer
Hope this makes sense. I don't mind losing the temp function but it would be great to keep it
