Eagle Cuda 350 S/Map

[chris_pyc]

I have an Eagle Cuda 350 S/Map i wanted to use on my boat. i have run the transducer wire to my main console, but i was wondering if there was a way to add a second unit to the transducer, or even extend the signal to the front deck of my boat for fishing. i was going to buy a 15 foot extension and then unplug from the console and plug in the extension but is there an easier way?

Thanks for the help.
