In hull transducers

[Anchor Wheel]

Lineman they have extensions, just do a search on the internet for the best $. Another option and upgrade as well would be the Airmar P66 transducer. They are reasonably priced, 600w, larger cone I think and come with enough cable for a forty footer practically. I made this upgrade last year to my HDS unit and I'm very happy!

I also bought a Airmar P66 last year, purchased mine from IMarineusa, works great!
