Devaux Gammarus HPN 02 Fly

Product strengths

The Devaux Gammarus HPN 2 are designed to accurately imitate gammarus (scud), a primary prey of trout and grayling in many rivers and stillwaters. Their precise construction delivers a natural drift and excellent hook hold, ideal for provoking strikes from pressured fish. A reliable choice for anglers seeking consistency and realism.

Technical features

• Realistic gammarus (scud) imitation for river and reservoir fishing
• Carefully crafted by Devaux, a benchmark in artificial flies
• Compact, balanced profile for a natural drift
• Durable finishes for enhanced longevity
• Hook suited for sport NO-KILL fishing (barb can be crushed according to local regulations)
• Colors and textures selected to maximize attraction
• Suitable for nymph-on-the-drop, French-style or slow wet-fly techniques
• Versatile use in clear waters, moderate currents and invertebrate-rich areas

Benefits and key points

Thanks to a silhouette faithful to a benthic crustacean, the gammarus fly triggers reflex strikes in pressured conditions. Its density and balance allow precise bottom fishing without excess weight. Devaux quality ensures a clean presentation, reliable hook hold and excellent durability even after multiple catches. Ideal for prospecting vegetated margins, runs and gravel bars where scuds abound, it entices selective fish with its realism, efficiency and minimal, natural action.

Usage tips

Use the Devaux Gammarus HPN 2 in nymph-on-the-drop or European-style methods with a fine tippet to optimize drift. Target slow to moderate lies, troughs and currents near weedbeds. Adjust depth via leader length and drift speed, maintaining contact without restricting the fly. In reservoirs, let it sink then retrieve very slowly with short pulls along the margins. Pair it as a tandem with a more visible indicator nymph on a dropper to serve as a reference, while keeping the gammarus as the discreet point fly. A soft, quick strike increases hookup rate.

FAQ

Is the fly suitable for clear, pressured waters?
Yes — its discreet profile and faithful scud imitation make it a highly effective option on wary fish.

Should I add weight?
Depending on current and depth, mainly adjust leader length. A discreet added weight can help in fast seams while preserving a natural drift.

Can it be used in reservoirs?
Yes — along margins near weedbeds and invertebrate-rich zones, using a slow, steady retrieve to mimic a moving scud.
