Advantages and key features

The Devaux Tungsten Nymph JBNT07 stands out through the use of tungsten, a dense material that guarantees a fast descent—essential to reach the bottoms where educated fish hold. Its design, both simple and sophisticated, perfectly imitates natural larvae, significantly increasing strike rates. Its precise, durable construction makes it ideal for regular sessions, offering a particularly attractive efficiency/price ratio. A true result of Devaux innovation, it is aimed at both specialists and newcomers wanting to maximise their results.

Usage tips and recommended rigs

For optimal effectiveness, it is recommended to fish the JBNT07 on a fine, inconspicuous tippet to preserve the subtlety of its presentation. It is ideally used with nymph-on-the-line techniques with a 10 to 11 ft rod, or with Czech nymphing to fish deep seams and fast current zones precisely. Its tungsten weight permits use on light weighted heads or even without additional weighting. Vary the drift or retrieval speed to find the most attractive action depending on current fish activity.

Testimonials and expert reviews

"Fishing trout in rivers very regularly for over twenty years, I adopted this new JBNT07 as soon as it was released in 2025. The build quality, the fineness of the finishes and above all the density of the tungsten ensure a rapid descent and a perfect presentation. Even on wary fish, it clearly makes the difference. I recommend it without hesitation to all demanding enthusiasts!" (Jean-Michel, experienced angler)
