Buddy at work bought some used units to put on a crappie boat. Asked me what all he needed to connect them up and I am not sure. He got an HDS Gen2 10 & HDS Gen2 8, an LSS2 Transducer and Structure Scan box. The only wire he got was the transducer cable. What other cables and such would he need to link all that together? I know he needs a NEMA2K start-up kit, and a couple ethernet cables maybe. What would be the power cord serial #'s he would need? Thanks a bunch guys.
