Powerful and full of the best Shimano technical innovation, the Big Baitrunner features a large AR-C spool with slow oscillation Aero Wrap II line lay. This combination ensures maximum distance casting performance. Internally all 5 ball bearings are shielded A-RB for increased durability and the gears have been redesigned to minimise friction and increase power transfer from the long aluminium handle to the rotor. This delivers more torque and winding power making fish playing easier and delivering more control. Available in two sizes, the Big size, with its awesome casting performance is perfect for the largest carp waters, whilst the smaller Medium version is the ideal choice for medium sized waters where casting distance isn't the most important requirement.
