Adding dual console mount. What is best mount for adding a Humminginbird Helix 10, I already have a Lowrance Hds 12@ console and another at bow (networked)..I know the hummingbird wont talk to other units.Would like to avoid moving Yamaha gauges if possible?? MR jones @ Jones trolling motor is awesome, he has answered several of my questions regarding my Ultrex service warranty and about electronics questions..wish he was closer to Chicago..
