The C&F Design Fish Eye, referenced CFT-10, is an innovative tool designed to enable fly tyers to see their creation through the eyes of a fish. Based on the theory of the critical angle of refraction, the Fish Eye offers a unique perspective on how a fly is perceived underwater, from the fish's point of view.
This unique tool includes a mirror and a device containing water, allowing users to easily observe the inside and outside of the "fish's window of vision" as seen through a fish's eyes, directly on their mounting bench. This ability to inspect the fly from an angle that simulates a fish's underwater vision is crucial to understanding and improving the effectiveness of fly tying.
The Fish Eye is ideal not only for checking flies you've tied yourself, but also for tying demonstrations, offering a fascinating and educational insight into the importance of fly design and presentation. Using the principle of the critical angle of refraction between water and air, the Fish Eye helps determine whether a fly will present itself realistically and attractively to target fish.
This tool is invaluable for serious fly tyers and anglers looking to fine-tune their creations for maximum effectiveness. By offering a direct perspective on how fish perceive flies underwater, the C&F Design Fish Eye encourages a more focused and considered approach to fly design, leading to better performance on the water.
