Smoke Black Tan Delta Extra Force fin.

Surprised I have a few Tan Delta Models to sell.  Very fast performance with Vortex generators back side to help you slip thru the water.  Of course their is a very special story on how Diver Skip Dunham asked for a Bigger Force Fin design for his hunting large Halibut off the California Channel Islands. You purchase and get the story about your special Force Fin.
