Depends on what he is planning on doing with it i guess. I have friends with trollers linked to their graphs and they dont use any of the features, so it isnt serving much purpose. I had a motorguide linked to my lowrance on my last boat, It was useless for what i used it for. If i was up North trolling cranks for walleye i would be all about linking them up to run contour lines, but in the Ozarks i found it worthless because i would always be dodging trees and stuff
