I currently have 3 with one on standby. 1 at the console and 2 at the bow. My current set up is 2 12" carbons and 1 8612. 1 carbon at console and 1 carbon and 1 garmin at the bow. Even though I have a ghost troller(being able to link is nice but.....).I would delete both lowerance lowerance unit and add a 1243 at the console. Just me... and I been a lowerance fan since the early mid 80's
