Thread: Shorten transducer cable

I have a 10m cable on my Tm260. I need about 1.0m of this for the worlds smallest offshore sportsfishing boat, and I am mildly concerned having the remainder coiled up and cable tied to the transom is causing some undetectable loss of performance.

Some people say you can't shorten transducer cables for some vague reason. Others say it's fine. Airmar sell the Tm260 as a "mix n match" setup with various cables which would indicate that it's actually fine.

What's the real story, and is there any outfit that offers the service?
