Strike indicators have been perfected with Oros. Say goodbye to common indicator pain points with the Oros strike indicator. There are no small parts to fumble and lose. Its 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. The Oros strike indicator encloses fastening hardware inside of two molded EVA foam hemispheres. When closed, the foam hemispheres compress creating a pressure fit lock that keeps it on the line and in place, without kinking. Over-sized threads make securing it to the line effortless. It works best when the indicator or your hands are wet. Unscrew the two foam-grip hemispheres and place the line in the screw slot. Holding the bottom half, with the screw post, in place, screw the top half of the indicator shut. Reposition the indicator between sections of line with just a half twist of the top and bottom.
