While virtually identical in appearance to the Seawing Nova, the Seawing Nova Gorilla uses a special additive in its compound to provide more stiffness and snap to the blade. This results in more power and control for divers who like a stiffer fin with more "feedback." The stiffer blade also allows for more effective sculling, frog-kicking and back-kicking, which makes it a good choice for tech divers. The fin features a well-engineered footplate with co-molded Grip Pads that improve non-skid footing on slippery boat decks or dive ladders. It also features a self-adjusting heel strap made of marine-grade bungee. A truly unique fin that has earned accolades since its introduction, the Seawing Nova Gorilla sets the bar in dive fin design.
