trolling depth for lures

[Kent]

My experience has been that the vast majority of fishermen/women think that they are trolling deeper than they actually are. I have had people study the books and I will ask them how deep they think that they are trolling. They give their answer and then I go through water that is shallower than they believed that they were trolling and their lure didn't hit bottom, so I know that they are shallower than they think that they are.
