Product advantages and strengths

The Devaux JBT 04 Terrestrial Flies offer multiple assets. Their meticulous imitation of shoreline insects triggers strikes from educated fish, maximizing your catch rates.

Their exceptional durability prevents premature wear and ensures many casts without loss of effectiveness. Thanks to precise tying, each fly maintains its qualities over many sessions.


Usage tips and recommended rigs

To get the most from these flies, favor use in flowing or still waters during terrestrial insect activity periods (spring to early autumn). A fine fluorocarbon leader promotes discretion.
