I know Lance very well and know why he calibrates his reels. It's to help all those that he is teaching. So they are all on the same page so to speak. But for the guy that fishes all the time. I just don't think it needs to be done. If you look at 800 RR, the difference between 18 and 24 ft down is 40 ft line out. the difference between 120 out and 160 out is 2 ft deeper. Now you take into acount the many currents out on Erie, the direction your trolling, you still don't know where your baits are running. It's a game changer. Cover the water column the best you can. find the depth/line out they want with the location, direction, type line your running and work from there on color, speed and line out.
But that's me.
