The Devaux Gammarus JBG00 Flies are based on an exclusive design developed by specialists in the discipline. Their blend of translucent synthetic fibers and natural materials creates an extremely lifelike silhouette and movement in the water. Every detail, from the translucent back to the subtle body hue, faithfully reproduces the morphology and nuanced tones of living gammarus. The carefully chosen hook ensures strength, hooking efficiency and discretion in currents, guaranteeing a neat and enticing presentation.

Benefits and highlights
- Extremely realistic gammarus imitation, significantly increasing your chances of tempting wary fish.
- Handcrafted with the quality standards that made Devaux famous.
- Remarkable durability and retention of appearance even after multiple catches.
- Suitable for both sight-nymphing and controlled drift techniques, across all current types.
- Universal compatibility with various techniques and leader configurations.

Usage tips and recommended rigs
To fully exploit the potential of the Gammarus JBG00 Flies, rig them on thin, discreet leaders (recommended diameter: 0.12–0.16 mm). They perform best with sight-nymphing techniques or delicate presentations in clear water. Ideal when paired with a light nymph tip to explore margins and slow drifts. For action, gentle twitches or natural drift animations effectively simulate the movements of a real gammarus.
