The JMC Astral spool is an additional spool specially designed to fit the Astral reel. It allows fly fishermen to prepare several types of line (dry, nymph, sinker...) and to quickly interchange them during fishing action, according to the needs of the moment. It's the perfect accessory to gain versatility and responsiveness, without compromising on quality, and is indispensable for demanding anglers who want to adapt in the blink of an eye to changing conditions on the water.
