Not a HB fan anymore.

Lowrance networking, you can read any transducer on any unit networked. Handy dandy. I have 2d si/di at rear. I have 2d/di mounted up front. I can pick and choose what shows up where via network.

I can also share "chip" maps via network. HDS Gen2. I can also make maps from Google and install on HDS. Just gotta know how.

Handy dandy stuff.
