Benefits and product highlights

The Devaux Gammarus and Nymph Flies stand out for their high effectiveness, thanks to striking realism and carefully tuned details that fool even the wariest fish. Designed by specialists, they deliver a natural swim and high durability against aggressive strikes from larger predators or selective fish. Devaux innovation is evident in material selection and tied balance, ensuring natural behavior in both fast and slow waters.



Usage tips and recommended rigs

Ideal for indicator nymphing, Euro nymphing or when bouncing the drift under the rod tip, these flies perform best on fine weighted heads or discreet fluorocarbon leaders. To maximize attractivity, use a fine tippet (0.12–0.16 mm). Experiment with slow drifts close to the bottom, especially early in the season or when fish are feeding on gammarus and nymphs.
