Jeff the networking capabilities allow you to connect another fish finder if you wanted a 2nd 1in the back of the boat, also allows radar, auto pilot, marine radio, etc to "talk" together and get overlays and operate them off of multiple units. This requires lots of cables, T's and such to connect it all together along with telephone wire for the NEMA stuff (very common use/install is in the off shore boats).
