The PENN® Battle IV is stronger and more durable than ever before. The Battle® IV features PENN's Hydro Armor sealing system that protects critical components no matter how harsh the conditions. The Battle® IV can withstand the force of big fish with PENN's proprietary CNC Gear™ technology and proven HT-100™ carbon fiber drag system. Each reel is factory matched with a graphite composite blank and premium cork and EVA handles. PENN's proprietary one-piece stainless steel Dura-Guides eliminate guide insert pop outs, one of the most common issues with traditional rod guides.
