Benefits and highlights:
Thanks to the clever integration of tungsten, the Devaux JBNT12 sinks immediately in the water column—essential to reach wary fish in deep zones or strong currents. Its highly realistic appearance attracts even the most educated fish, while the quality of the tying and materials ensures exceptional hook-hold performance. The robustness of the assembly extends its lifespan season after season. Anglers will also appreciate the perfect balance between weighting and controlled buoyancy, allowing all variations of controlled drift and tight-line nymphing. Ideal for fast runs as well as calm pools, this artificial fly meets expectations in mountain streams and lowland waters alike.

Usage tips and recommended rigs:
It is recommended to pair the Devaux Tungsten Nymph JBNT12 with fine tippets for a natural presentation. Using a light leaded-head setup maximizes depth control. For tight-line nymphing, gentle animation is advised to let the fly evolve naturally in the current. In both reservoirs and rivers, alternate between dead drift and slight pulls to enhance the fish’s visual perception. Adjust your leader according to water turbidity and fishing pressure on the spot.

Expert testimonial:
“Having tested the Devaux JBNT12 since its release in 2025, I was amazed by its ability to descend quickly to the fish and its stealth once submerged.

This nymph has become a must in all my sessions, both on technical rivers and wild beats.” – Michel D., angling enthusiast
