Bassin Bob, just a reminder. Be careful not to equate where you see the weights on the fishfinder with their actual depth. The fishfinder is measuring from the transducer to the weight ie. at the angle of the blowback. The only time the depth of the ball and the fishfinder reading are the same is with no blowback.. For example, it would not be unusual for the fishfinder to show 120 ft and the weight only be down 100 ft., at trolling speed. Of course the difference varies with boat speed, depth being fished, and size of the weight.
