I currently have a fcv 585 and navnet 2 nt and I am looking to upgrade to the tz9 and a gp33 for a backup and keeping the Fcv585. I am wondering if I can link the tz9 and the fcv585 together, use one transducer for both units? Do I need a black box to run the tranducer through the tz9? Is the FCV 585 worth keeping or will the tz 9 be a better sounder. I am not planning on upgrading to the chirp right now. I have a airmar b164 through hull transducer
