You're never stuck in a fishing funk with a HT Polar Tip-Up with Quick Change Spool. The Polar is a favorite choice for its frame design, smooth operation and no-freeze-up guarantee. Now it's the first to have an interchangeable spool. Avoid the delay and frustrations of needing to change line color, going from lighter to heavier backing, different hook style or the frustration of a wind knot. A simple wing nut assembly holds the interchangeable spool, remove, replace and resume fishing. As always, the multiple set trip shaft allows for heavier baits and harder sets, too.
