I have been Lowrance since the lcx days, however my 2017 boat will have helix 10s on the console. I plain on running a 10si and a 10sonar/gps next to each other. This is 2500$ retail. The single Lowrance hds9 gen3 is 2300 plus the 3D structure scan. I love the Lowrances and their customer support, but I'd rather have 20inches of display.
