Benefits and key features of the product

The JBNT25 Devaux nymphs benefit from a design based on innovation and in-depth knowledge of aquatic environments. Tungsten weighting allows them to reach the bottom quickly, where trout and grayling often hold, even in strong currents. Their refined profile optimizes a natural underwater drift, and the range of patterns covers most situations, whether fast rivers or calm bays. The overall robustness ensures superior longevity against underwater obstacles and powerful strikes. Their success also lies in their ability to adapt to the increasing wariness of modern fish.


Usage tips and recommended setups

To get the most out of these nymphs, fish them using a tight-line nymphing technique, adjusting depth according to the target fish size and current speed. A fine, discreet leader head will enhance presentation naturalness. When used in tandem with a dry fly or a lighter nymph, you increase your chances of provoking a strike. Ideal for river fishing during hatches, they also deliver excellent results in reservoirs on wary fish.
