Advantages and key strengths of the PRO'INDICATOR :
The Devaux PRO'INDICATOR stands out for its innovation and ease of use at the water's edge. Its ingenious attachment allows the angler to change fishing depth in seconds without having to dismantle equipment, saving valuable time when adapting to river conditions. Its highly visible color maximizes strike detection, even on rivers with changing reflections or at dusk when light fades. In addition, its weighted yet buoyant design ensures outstanding performance by limiting unwanted movement on the leader while providing immediate responsiveness to the slightest contact. Made from high-quality materials, it withstands repeated use, sun exposure and fresh water wear. The PRO'INDICATOR thus asserts itself as an indispensable tool to advance in delicate salmonid fishing.

Usage tips and recommended rigs :
To get the best from the PRO'INDICATOR, simply make a loop with the leader to attach the indicator. This simple operation allows it to be moved easily according to the targeted depth, enabling quick adjustments at each fishing spot. The indicator pairs ideally with tapered leaders and weighted nymphs to maximize a natural drift. For increased visibility during long-range fishing or in turbulent water, it is recommended to treat the PRO'INDICATOR with the O’Fly Insubmersible additive to reinforce long-lasting flotation. Compatible with all types of fly rods, it is suitable for both lowland rivers and mountain torrents.

Expert testimony :
*“Since the release of the PRO'INDICATOR in 2025, I have adopted it systematically for trout nymphing on the dropper. Its ease of setup and, above all, its ability to stay in place without disturbing the drift have made me more effective. Takes are visible at a glance, even on wary fish or long drifts. A modern reference for demanding anglers!” — Jean L., experienced guide angler*
