Re: Two depth finders one transducer?
Depends on how much money you want to spend. If you don't need the transducer for the helm unit buy a transducer extension cable for $40, run it up to the flybridge and your done.
If you want to use both as UncleWille noted, you have to buy and install a NMEA starter kit ~$80 and a couple of drop cables for $20 each
