Advantages and strengths

This gammarus imitation relies on convincing biomimicry: rounded back, marked segments, translucency and micro-sparkles that mimic the chitinous shell of a freshwater crustacean. It excels when fish feed near the substrate or in weedbeds, where discretion and density make the difference. Its design allows a progressive water entry, limiting splash and preserving the trust of wary fish. The effectiveness is noticeable year-round, peaking in spring and autumn when gammarus are abundant. Thanks to its robust tying, the fly keeps its shape and sheen after many catches, ensuring superior durability.

Usage tips

To get the most from the Gammarus GAMT 2, favor a slow, controlled presentation. In rivers, fish margins, pool heads and riffles with an upstream drift while maintaining contact. For indicator fishing or sight nymphing, adjust depth with a tapered leader and use a subtle visual indicator if needed. In reservoirs, fish along breaks and weed edges with minimalistic animation, skimming the bottom and adding pauses. Pair with a fine tippet and regularly polish the tip to maximize discretion. In clear water, slow the drift to imitate a gammarus lifted a few centimeters from the substrate.

Testimonials

"Tested from its release, the Devaux Gammarus GAMT 2 became a staple on my calcareous runs. The drift is stable, the imitation very credible, and picky trout often decide in the last centimeters. In reservoirs, it has produced several key fish on days without hatches. A reliable choice when gammarus form the basis of the food supply."
