I just bought a new boat and asked for an upgraded hummingbird on the dash so I can install my Helix 9 g2n on the bow and network them. So, I now have a Helix 7 g3n, adapter and network cable (have to purchase another adapter cable). I called Humminbird to see which transducer they recommended and was surprised. They suggested the xnt 9 hw msi 150t compact transducer that came with the 7 (because its gen3) and not the big xp9 20 msi t that came with the 9.
Does anyone have anything productive to share on networking? This will be my first networked system.
