Category 3 Gummers Carpet Caddis - Black Tungsten Bead

Pick the bead size, and you have picked the depth

The size range does more than change the fly's dimensions. A 4mm bead on a size 10 is a bomb that will hold the bottom of a heavy run, while a 2.5mm on a size 16 slices the surface tension and settles slowly through shallower water. Choosing the size is choosing how deep you fish, which is why it pays to carry a spread rather than one. The black bead keeps the front end quiet for clear water and fish that have seen plenty.
