For musky and pike fishing, you need heavy-duty baitcasting reels, such as Shimano Tranx or Daiwa Lexa models (300-500 series), with a power handle for retrieving large lures and strong line capacity. A moderate gear ratio around 6.3:1 is a versatile choice for different retrieves, while a high-speed ratio (7.1:1 or higher) is beneficial for quick hook sets and fighting strong fish.
