Penn Slammer IV Series Spinning Reel

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.

These reels can work great with braid as well as monofilament lines from all top manufacturers. We personally recommend using braid as the mainline on top of some mono backing to use to stick to the spool and to fill the base layer of the spool with mono so you can save money on the braid. 

Our 2 favorite lines for the Slammer IV is Daiwa J-Braid x8 Grand and PowerPro. in the 10 lb to 30 lb range depending on what species you're targeting.
