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.

Breakthrough Design

  • Exceptional performance

    Oros strike indicators enclose fastening hardware inside of two foam hemispheres. When closed, the foam compress creating a pressure fit lock that keeps it on the line and in place, without kinking. Large screw threads make securing it to the line effortless, and it it's even easier to lock in place with wet hands.

  • Less pain

    Oros strike indicators eliminate common indicator pain points. There are no small parts to fumble and lose. It’s streamlined design is centered on the line for balanced casting. There is no exposed fastening hardware or posts sticking out to create drag or tangle line.

  • Mix or match colors

    Personalize color combinations for optimal visibility and sensitivity under various conditions.


"Oros indicators are a must for me when heading out to the river. Their ease of use in all weather conditions and secure holding on the line make them the perfect tool for anglers of all abilities. I use them with my family and clients alike."

Oros strike indicators are astoundingly easy to put on and take off, and a piece of cake to adjust. This is about as perfect of a product the fly fishing world will see for a long time."
