Dinsmores Clip-on Plummets are special weights used to determine the depth of water you are fishing in.
Simply clip the hook into the plummet, if your float submerges you will need to move the float up the line until the correct depth has been found.
Your float should be sitting just proud of the water surface.
2 clip-on plummets per pack.
