Baitcasting reels is a type of a fishing reel with a movable spool and it is a direct descendant as well as the result of the development of the first and relatively simple structures with a movable spool. Contrary to the traditional fixed spool reel, the multiplier is equipped with a main axis supported by two points. There is a spool on this axis. The entire drive mechanism is synchronized with the guide - the guide responsible for evenly distributing the line on the spool.
The main advantages of multipliers are their durability and resistance to significant loads. Another and significant advantage of the baitcasting reel is the movable spool, which rotates during the cast, feeding the line, thanks to which there is no resistance associated with friction of the line against the spool's edge.
