Product Description
Rio Deep 7 Sinking Lake Fly LineThis full sinking fly line was developed for the expert competition reservoir "buzzer" or chironomid anglers who need to get their flies down deep fast. The Deep 7, built on an ultra thin, single strand monofilament core, is one of the fastest and most durable sinking lines in the world. It gets flies down deep and generates high line speed. North American anglers find it useful whether fishing in waters such as the Kamloops area of British Columbia or the desert lakes of the U.S.
