Lock weights are very similar to bank weights, except they are flat on their sides. This feature is great for when fishing in heavy current and you do not want your weight to roll around on the sea floor. This same effect can also be great in the boat when fishing with novice anglers. The flat sides keep the weight from rolling around on the deck of the boat.
