Strike indicators can be a pain to use. The tiny parts to fumble and lose, and can become 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. 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. Oros Strike Indicators are made with a biodegradable additive that rapidly enhances the ability for plastic to biodegrade in natural environments.
