I have a 788 on the bow of my triton, the transducer cable is bad, so that sounds like a good reason to upgrade (doesn't it?) I was going to a Helix7, but then found that the 7 is not HD, but the 9 is. Now I'm thinking 9 (di), but see the 12 has chirp. questions;
1. is chirp worth the extra money?
2. I'm planning on just di. are there any issues with mounting a 9,10,or 12 on the bow with transducer on the trolling motor?
3. they will all Ethernet to the 998 that is at the console?
