Theo's biot stone (black bead head)

Bead head fly fishing patterns are designed to be fished under the surface of the water. The bead helps add weight to the fly allowing it to sink to the bottom of the river or stream. Bead head flies can also be fished in lakes or ponds either by using a strike indicator, or with a sinking fly line. If fished in a river, the bead head pattern will either bounce along the bottom, or if the current is fast and deep enough in the middle of the water column.
