I feel everybody's pain, I once had my uncle from florida (who is an avid fisherman in florida, but extremely unfamiliar with trolling the great lakes) on the boat and he watched as I set up and changed programs a couple times so felt comfortable pulling in lines. He thought the riggers stopped automatically when the ball came all the way to the top. They do not. Lost three 12lb. Balls that day, no probes or releases but It was an expensive day. Straightened out all the weight clips. He felt bad but now we laugh about it.
