For large fish to be successful, they require strong and smooth drag.

This is a simple fact about salt.

A drag system can help you exhaust powerful fish and make them more likely to steal your line. Your drag should be set at 1/3 of the line’s test strength. This will protect your line and knots from sudden shocks, which can prevent them from bursting.

That makes me believe that drag is the most important component of my reel and the first thing I see.

Penn created the Slammer III to be stomach-bruising and arm-fatiguing. The phenolic-coated carbon fiber washers, which do all the heavy lifting in the drag system’s drag system, are all business. They provide plenty of reliable, smooth pressure and are both durable and powerful.

They will allow your fish to line up at the exact setting you require, and they will do so without any stops or starts. Penn is known for being smooth and reliable in tough battles.

The Slammer III delivers the performance you expect and is a top-quality drag system.

Although the drag system is resistant to saltwater spray, I don’t recommend using it as a paddle.


You need to maintain a tight line when dealing with a bull red, sailfish, or mako.

Penn is well aware of this and has equipped the Slammer III lineup’s lineup with exceptional gear ratios that are matched to huge spools. These design features work together to provide exceptional retrieval rates.

The smallest Slammer III can pick up 37 inches per turn and the largest, 49.5! You can be sure that no matter what size you choose, you will have the speed you need.

This reel features Penn’s solid brass gears. It is worth remembering why. While brass isn’t as lightweight or as tough as aluminum, it is more durable over time. You can also machine it more precisely which results in smoother gearing at a lower total cost than other options.

Brass can be used to make very fine gear teeth. It’s also soft enough to machine easily. You will notice the difference in your line – a “connected”, or “grounded” feeling.

It’s still quite heavy, compared to aluminum. Penn made the right decision to use sturdy, beefy gears while focusing on weight savings.

This seems like a sensible design choice. You’ll love the feel of these gears and their strength during a fight.

The capacity of the spool


This is what I think of the Slammer III spools.

The Slammer III series is marked with capacity lines on both sides of the spool. It holds enough line to hook any type of hook, even braid, and it’s easy to swap out your mono for braid.

Consider numbers as805 yards braid of 50-pounds on the 10500, or440 yards braid of 50-pounds check out the 7500!

These are some staggering lines, and Penn clearly considered the types of fights that you might encounter while fishing for pelagic species.

Casting and retrieving

Although the large reels don’t have the best casting performance, they can provide distance when needed.

This is because the bodies and spools are of the highest quality, with the reels at a safe distance.

The Slammer III cranks like magic, as you would expect from one of the most exquisite brass gears on earth. It offers a head-turning torque and ultra-smooth performance. Your rod will do most of the work, but the power of these gears will make it easy for you to rest easy.


The price is usually weight, but strength, durability, power, and power are not cheap.

The Slammer III series features a large capacity spool, solid brass gearing, and the same feel that made Penn a saltwater legend.

Penn designed these reels with an aluminum body and a machined handle. This helped to reduce the heavyweight of the reels. It also provided rigidity for hard work. It’s not exactly slimming, but the final numbers are just as impressive as you would expect.

For the 7500 and 8500, think about 2 pounds and 43.1 ounces respectively. The 10500 will take you home with it.

These are acceptable weights considering the purpose of these spinning reels. If I was chasing fish that are not caught on conventional reels, these would be my preference.

Final Verdict

The Penn Slammer III spinning reel is one of the most expensive for large saltwater species.

This is a bold statement, but a close look at these reels supports it.

They have the drag systems to win tough fights with big fish, the ability to work monsters, and the gearing that allows you to get on the line whenever you can. The Slammer III is your ally in these types of fights. Every inch you win is a victory.

The Penn Slammer III is the best choice for anglers who prefer a spinning reel over the traditional alternative.
