What Our Gearhead(R) Experts Are Saying:"When I'm switching from dries to nymphs or need a backup rig for different water types, having a spare Battenkill Disc Spool in my kit is a must. It's super lightweight, built to last, and integrates seamlessly with my Battenkill Disc Reel-plus, it's machined aluminum, not plastic."When we're out on the water chasing different hatches or exploring varied stream conditions, a backup line setup can make or break a session. That's why we keep an extra Battenkill Disc Spool in our gear bag. Designed by Orvis to fit the trusted Battenkill Disc Reel, this machined aluminum spool lets us switch between floating, sink-tip, or full-sink lines in seconds-without needing a full second reel. Built from 6061-T6 aircraft-grade aluminum, this spool is just as tough and corrosion-resistant as the reel it matches. It includes an ergonomic Delrin handle for smooth operation and secure grip with wet hands. Whether we're on the flats, the riverbank, or deep in the backcountry, the Battenkill Disc Spool ensures we're always rigged for the moment.
