The Sonar Leaders work great for getting flies down to deeper areas. The micro-swivel helps prevent tangles and the welded loop makes attaching to the fly line easy. I’ve used them on both single and double-handed lines and they perform consistently in different water conditions.

I found the 10ft length to be perfect for my fishing setup. The sinking options allow me to target fish at various depths. The line doesn’t twist much thanks to the micro-swivel, which makes casting smoother.
