I want to add a second screen so I can PRIMAIRLY see Sonar / Fish Finder. I do not want to add a second transducer to my small boast. What humminbird models if any can I use networked to my 981c?
If you are wanting sonar on both units than you will have to install a second transducer for the second unit – the 981c Si unit cannot share sonar with another unit. To do this both units would have to have Ethernet connection capability like the 798ci HD Si, 898c Si, 998c Si and 1198c Si units have. This cannot be added onto the unit but has to be built into it.
Can I network my 1197 with 998c SI CBO?
