When originally developed, Penn developed the Slammer Liveliner with a manual feature that required the angler to flip the Liveliner drag lever to engage the fighting drag. This made sense as it allowed anglers to easily control their bait without engaging the fighting drag. However, angler after angler, captain after captain, inquired as to why Penn did not have an automatic liveliner feature. Penn has always prided itself on building products that served their anglers. Now Penn offers the Slammer Liveliner with an automatic feature.
The Slammer Liveliner still maintains its roots as the most durable, reliable, and quality built spinning reel on the market. Just like the Penn Slammer, the Liveliner version features full metal body and all the other things that go into making the Slammer family of spinning reels the preferred choice of top captains and professional guides.
