Harnesses by themselves have no diving qualities so with the Wt. 20ft ahead of the harness you should be able to tell how deep the wt is but the harness will be forced up by the water pushing it upward. If you change to inline Wt. system you will have a better knowledge as to where your harness is because it will be only the length of your leader away from your weight. The snap wt system works best with crank baits because most cranks have some diving ability keeping it in the targeted zone. But that diving ability has to be considered also when using the snap Wt. system as it will add depth to the known depth of the snap Wt. you are using.
