SA Sonar Sinking Leader
SA Sonar Sinking Leaders attach to the end of a fly line and can put your fly anywhere in the water column. Sonar leaders feature welded loops on the rear end and a micro-swivel on the front end to reduce line twist, with the exception of the floating option which does not have a swivel. With the versatility of five different densities, you’ll be able to cover the water column from the surface to the depths. Ideal for single-handed lines as well as light double-handed lines. No matter the scenario, you can get down with SA Sonar Leaders.

I’ve used the 7′ sinking leader with my single-handed setup and it’s made a big difference in reaching deeper waters. The micro-swivel keeps the line from twisting, which helps with casting accuracy. Easy to attach and reliable in various conditions.

The 10′ leader works well for light double-handed fishing. It sinks steadily and stays taut. No issues with line twist thanks to the swivel. A bit heavier than expected, but worth it for depth control.

I switched from a standard leader to the Sonar sinking option and noticed better fly placement. The welded loop makes attaching to the fly line quick and secure. Great for targeting deeper fish.
