I would mount Lowrance carbon units on both bow and dash. Network them together with 1 Ethernet cable and share all waypoints, maps and transducers from either machine. Solarmax HD screens (can view with polarized sunglasses), dual processor, genesismaps.com for free mapping, can add the 3D structure scan for best clarity of side and downscan and can be viewed from either unit. Also the physical size of the units are smaller than the humminbird so you can have more dash area
