Advantages and strengths

Inspired by one of the most consumed natural foods by many salmonids, the gammarus fly accurately reproduces the posture and tones of a freshwater crustacean. Its calibrated density allows it to reach the target water layer quickly while avoiding sudden pulls. This fly excels when fish feed close to the substrate, notably on shallow runs and margins rich in aquatic vegetation.

Its reliable construction limits material wear and preserves an effective look cast after cast. In low water and in high flows alike, the GM 6 maintains a discreet visual and vibratory signature, ideal for wary fish. The quality hook provides excellent hookups while ensuring secure holding during the fight.

Usage tips

To get the most from the Devaux Gammarus Fly GM 6, favor a slow, controlled drift near the bottom. When nymphing on a long leader, accompany the fly keeping a slight tension to feel the slightest take. With an indicator, set the depth to graze the substrate without snagging. For a lightly drowned presentation, alternate short pulls and pauses to mimic gammarus movements.

Approach discreetly, cast upstream and let the fly position naturally in water lanes rich in weeds, holds and stones. Stay alert to subtle takes, common when fish feed close to the bottom. Gently clean the fly after each outing to preserve its sheen and shape.

Testimonials

“Tested at season start and peak, the GM 6 allowed me to fool selective trout in clear rivers. Its descent is steady, the holding in current excellent, and hooksets are clean. A must-have whenever fish target gammarus along margins.”
