What is the difference between an $85 4000 size reel and a $125 4000 size reel both made for the same company? I get this question all the time from customers looking at the Penn Fierce and the Penn Battle. They both come with a standard 6.2:1 gear ratio, an aluminum body, the HT-100 drag system, and weight about the same. The extra $40 for the Battle comes from the ball bearings and gears. The ball bearings found in the battle are all sealed which helps keep the saltwater from corroding them. The Battle also has the CNC Gear™ technology, this means that instead of the gears being made from the mold they are directly cut from a piece of metal. This allows the gears to be strong and to fit into each other better. So, in the end, the extra $40 will get you a smoother, stronger reel that can handle being hit with some saltwater. If it was me deciding between the two, I would spend the extra $40 for the Battle. I treat all my reels as investments and know I will have them for many years. Those upgrades in the Battle give me confidence that I will not have any problems with the reel and that it will last longer than the Fierce.
