When I started shooting docks available information was pretty hard to find. As the years passed I picked up some things along the way. I certainly added some shooting irons. Advancements in electronics and trolling motors have made things easier as well. Before spot lock if the wind was pushing you into the dock and you couldn't fish the downwind side. You hade to go find another dock out of the wind. These days point the trolling motor into the wind, hit spot lock, then shoot under the dock from the back deck
