When you need a Spinning Reel that can handle the toughest fishing conditions, the Penn Slammer IV is built for the job. This full-metal powerhouse is stronger, more durable, and smoother than ever, thanks to an upgraded drag system, CNC-machined brass gears, and IPX6-sealed construction. The Slammer drag system is now even better sealed, providing smoother operation and greater adjustability under extreme pressure. Dura-Drag technology (models 3500–10500) delivers exceptional stopping power, while HT-100 carbon fiber drag washers (on the 2500 model) ensure a smooth and reliable drag for lighter fishing applications. The full-metal body and side plates keep the gear alignment perfect, even under heavy loads, while IPX6 sealing prevents water and dirt from entering critical components—extending the reel’s lifespan. The CNC-machined brass main gear ensures maximum strength and durability, and the 8+1 stainless steel bearings provide buttery-smooth operation. Additionally, the hydrophobic line roller bearing reduces water and salt buildup, improving line management and longevity. Models 3500–10500 come with an extra power handle with an EVA knob for better grip and comfort during long battles. Whether you're chasing sea bass on the coast, battling tuna offshore, or targeting monster pike in freshwater, the Penn Slammer IV is the reel you can count on—cast after cast. When only the best will do—choose the Slammer IV!
