If I have a cable hooking the 2 LSS the units would they still only read their individual transducers? On the bow am I ok going with LSS 2 or should I try to find a LSS 1? Or should I consider the HDS Touch 7? Is the NMEA2K network box (I assume it is a box) expensive?What part of IN are you in? I am in Southern IL just west of Evansville, IN about 40 miles.DanGRR884Dan,External Antennas will require a NMEA2K Network. Ethernet cable runs between your HDS and LSS unit. You could run another ethernet directly between the LSS units and then all your units would be networked to share info like transducers, waypoints etc.
