Up until last year, my sonars have been 1980's technology. I finally bought a LCX38HD last year for the console and am thinking of getting one of those new Lowrance HDS units for the bow. I keep hearing about people networking their units, but don't know anything about this. What advantage would this give me?

I did it with my Humminbird units using their interlink. not sure how the lowrance work getting them to work together. Its a great thing. I can save a wave point up front and it is saved on both. I also can check temp from both units . It is well woth it to link them together.
