One quick question. I have used dipsies quite a bit for salmon on Lake Michigan and we are always going over 2.5 mph. The PT App also bases their dives charts on that speed as well. Wondering if you have experimented with trolling the dipsies at slower speeds, especially as the water cools. I saw a lot of boats using Dipsies while we were in Huron this fall & wondered how fast they were trolling them that time of year as I know the slower speed will affect the depth quite a bit. Thanks again for the very informative post.
