Got a buddy on the Illinois board, brianlg, who's considering a Humminbird SI unit. Probably a 797 but he likes the 1197 better -- cost is obviously an issue.

Mike, I know you have the SI and wanted to get your thoughts on it. I know there are others here on the MO board that have them and I'd welcome your input, as well.

What do you like/don't like? Are they worth it? I've read/heard about some GPS issues with the units and wasn't sure if this was true or not.

Also, other threads on the main board have talked about Lowrance coming out with some sort of SI capability later this fall. Any and all input on this topic is welcome. Feel free to PM brianlg directly, too.

Thanks!
