The Signature "Quick Change" Underspin is quite the little engineering project...let us explain why! Now anglers get an underspin that not only balances well when matched with the appropriate trailer, but also has a screw lock to secure your trailer and also a "connector" that allows you to change blades when you desire something a little different for your specific fishing needs! Just push up the sleeve and slide on whatever blade/swivel that you want....or fish it as provided!
