An Incredibly Advanced Nymphing Line, Ideal For Fishing Indicators Out Of A Boat. The Xtreme Indicator line has been designed to be a very effective tool for anglers that fish nymphs and indicators out of a boat. The short head has a powerful front taper that casts indicator rigs with ease, and loads up with a single cast. Built with RIO's low-stretch ConnectCore Plus, the line allows for intuitively better cast timing, easier line lifts and sharp, precise mends. Lack of stretch also means faster reaction time when setting the hook.
