Scientific Anglers Sonar Leaders – Sinking Leaders for Fly Fishing

The Scientific Anglers Sonar Leaders are sinking fly fishing leaders designed to get your fly precisely where it needs to be in the water column, even when paired with a floating fly line. These leaders attach directly to the end of your fly line and are available in multiple densities, allowing anglers to target fish from the surface all the way down to greater depths. Compatible with both single-handed and light double-handed lines, the Sonar Leaders offer a versatile solution for a wide range of fly fishing scenarios.

Built on 25-lb. monofilament, these leaders are constructed for durability and dependable performance. A welded loop on the butt end ensures a secure, streamlined connection to your fly line, while a micro-swivel on the front end helps reduce line twist during casting and retrieval. A printed Line ID on each leader makes it easy to identify the density and length at a glance, keeping your time on the water organized and efficient.
