Benefits and strengths of the product:
Using the Devaux Gammarus Fly JBG01 guarantees unmatched attractiveness to trout, grayling and other fish that feed on gammarus. Its studied silhouette produces a natural swimming action in the current, promoting decisive and repeated strikes. The choice of enhanced materials ensures durability over multiple fishing sessions, while the subtle finishing deceives even the most selective predators.

Usage tips and recommended rigs:
To fully exploit the potential of the Devaux Gammarus Fly JBG01, favor a sight nymph presentation or a controlled drift adapted to the fishing spots frequented by fish. Use a fine tippet (0.14–0.18 mm) to accentuate the natural drift. A rig with a micro-leadhead can be considered for fishing in deep zones or strong currents. Also vary retrieval speed to best mimic gammarus behavior in their natural environment.

"Since its release, the Gammarus Fly JBG01 has helped me fool superb trout on heavily fished sections. The realism of the tying and the quality of the swim make it an indispensable asset for any demanding fly angler." – Laurent R., professional angler (2024)
