The Slammer has been Penn’s higher end workhorse line for years through each generation, and the IV is no different. They maintain and improve on the great water resistance they added in the last generation with the addition of a hydrophobic line roller bearing, improving one of the most commonly replaced part on any spinning reels. They continue using the CNC brass main and pinion gears which add great durability and smoothness over aluminum or other common gear materials. They are an all metal reel with the frame and sideplate being durable enough for all saltwater applications, and a rotor that will hold up to high drag pressure. The drag system is as good as ever with some improvements to heat dissipation which will help out on longer fights with bigger fish.
The Slammer IV is packed with more features than ever before. Building off of our proven IPX6 sealed body and spool, we redesigned our Slammer® drag system to not only be better sealed, but also offer a wider range of usable drag, all while being bearing supported for extra smoothness. Adding our all brass CNC gear technology, 8+1 stainless steel bearing system and Hydrophobic Line Roller Bearing has made the Slammer IV the ultimate workhorse reel.
