Why We Picked It:
The PENN Slammer IV Spinning Reel is a powerhouse designed for expert anglers who demand extreme durability and performance in the toughest saltwater conditions. Built with PENN’s Full Metal Body and CNC Gear™ Technology, the Slammer IV ensures unmatched strength and smooth operation under heavy loads, the heaviest fishing applications, and in the absolute toughest fishing environments. The Slammer IV’s Dura Drag System was completely redesigned and upgraded from previous models being better sealed and much smoother. PENN went out of its way to test this upgraded drag system on the toughest fish, like Bluefin Tuna! Its IPX6 Sealed Body and spool design protect internal components from water intrusion, making it ideal for surf fishing, offshore battles, and inshore pursuits while keeping it as strong and smooth as the day you open it out of the box.

THE WEIGHT! PENN is noted for making durable powerhouse reels. However, this durability often comes at the price of the reels weight, but no the Slammer IV! This reel is lightweight and super smooth, as the Slammer 4 features up to 15% weight reduction from previous versions. Its solid all brass CNC gearing and 8+1 high quality Stainless Steel Ball Bearings make this reel incredibly smooth to operate. This is the perfect spinning reel for saltwater lure fishing, kayak fishing and boat fishing where a tough dependable reel is needed.
Plenty of options for reel range of sizes, which is quite impressive, from 2500 all the way up to 10500 with high speed versions also available, PENN really did think of it all with this reel.
