Benefits and product highlights
The Devaux EMERGENT FLIES HL21 deliver striking realism by perfectly reproducing the key emergence phase, making them an irresistible lure for most salmonids. Their precise tying ensures optimal durability, even after numerous casts. The use of innovative materials provides both low visibility and good detectability, making the fly effective in varying light conditions and water clarity. Carefully selected hooks ensure excellent hook-up rates while minimizing drop-offs.

Usage tips and recommended rigs
To get the best from these flies, opt for a thin leader or fine tippet to ensure a natural presentation. Preferably use a light weighted head if the current is strong to promote a controlled descent. A subtle action alternating pauses and slight twitches will perfectly imitate the insect during emergence and increase strike rates. These flies are ideal for river fishing during mass hatches, as well as on more technical beats where fishing pressure is high.
