Strike Indicators Don’t Have To Be Frustrating

“Strike indicators are a pain to use. They have tiny parts to fumble and lose, or are not balanced on the line. Some have parts sticking out that get tangled. Applying, adjusting and removing strike indicators from the line is challenging in the best of conditions, let alone when it is cold. I haven’t found the perfect strike indicator until now.”

Patrick Douglas - Founder of Oros Fly Fishing and inventor of the new Oros Strike Indicators.
