Humminbird Network Question

[Retro Active]

I have an 898c SI unit and am considering a 2nd HBird. I want to get something I can network with the 898, but I'm not looking for a 2nd SI unit.

Can I network a 7xx series (or maybe even an new 6xx series) unit with 2D and possibly DI with the 898, understanding of course that I won't get SI on the 2nd unit? Will the transducer allow SI on the 898 at the same time as 2D on the front unit, or do the two units have to be displaying the same?

Thanks!

I believe any of the hd units will network. I run a 788 and a 998 networked. I would asume both will run off the si ducer too. The non si/di unit will only have 2d. I run the si ducer and a thru hull, but its the same concept as just the si.
