Rubber O-Ring Yarn Indicators
Yarn O-Ring Indicators are a great way to detect strikes while fishing nymphs. The O Ring design allows you to attach the indicator without cutting the leader. To attach fold the leader in a loop small enough to fit through the O Ring. Push enough leader through the O Rig to allow the indicator to fit through. After the indicator has gone through the loop pull the leader snug to hold in place. To adjust push open the loop in the leader and slide the indicator as needed.
Try Dry Fly Dressing on your indicators to keep them floating high on the water.
