Fishing Line 101: Braid, Monofilament, Fluorocarbon & Pound Test

Fishing Line 101

Fishing line is one of the simplest pieces of fishing tackle, but choosing the right line can make a huge difference.

Should you use braid or monofilament?

What about fluorocarbon?

What does 10-pound, 20-pound or 30-pound test actually mean?

And when should you use a leader?

For saltwater anglers, especially those fishing the Georgia and Northeast Florida coast, understanding fishing line doesn't have to be complicated.

There are three basic types to understand:

• Braided line

• Monofilament line

• Fluorocarbon line

Each has advantages, and each has situations where it makes more sense.

Braided Fishing Line

Braided line is extremely popular among inshore saltwater anglers.

It is made by weaving multiple strands together, creating a thin line with a high strength-to-diameter ratio.

Advantages of Braid

• Strong for its diameter

• Excellent sensitivity

• Low stretch

• Allows longer casts

• Good for working artificial lures

• Excellent for many inshore applications

Because braid is relatively thin, it also allows anglers to put plenty of line on a reel without using an excessively large spool.

When Should You Use Braid?

Braid is an excellent choice when fishing:

• Artificial lures

• Soft plastics

• Jig heads

• Topwater lures

• Grass flats

• Marshes

• Creeks

• Docks

• Piers

For many inshore anglers, braid is the main line while fluorocarbon or monofilament is used as the leader.

Monofilament Fishing Line

Monofilament, commonly called mono, is a single strand of nylon line.

It has been a standard fishing line for generations and is still useful today.

Advantages of Mono

• Affordable

• Easy to handle

• Some stretch

• Floats

• Simple to tie

• Good for beginners

That stretch can actually be useful in certain situations.

Mono can help absorb sudden surges from a fish and can be useful when fishing certain topwater presentations.

When Should You Use Mono?

Mono works well for:

• Beginners

• Bait fishing

• Some topwater presentations

• Leaders

• Simple spinning-reel setups

• Situations where stretch is beneficial

It's also a perfectly reasonable choice if you're just getting started and don't want to overcomplicate your tackle.

Fluorocarbon Fishing Line

Fluorocarbon is often used as leader material rather than as the main line on an inshore spinning reel.

It has characteristics that make it useful around clear water and structure.

Advantages of Fluorocarbon

• Abrasion resistance

• Low visibility underwater

• Sinks

• Relatively low stretch compared with mono

• Useful around rocks, oysters and structure

Fluorocarbon is especially popular when fish are wary or when you're fishing around abrasive structure.

A common setup is:

Braided main line → fluorocarbon leader → hook or lure

What Does Pound Test Mean?

Pound test refers to the approximate breaking strength of the line under specified testing conditions.

For example:

10-pound test is designed to withstand roughly 10 pounds of pulling force under those conditions.

But don't assume that using heavier line automatically means you'll catch more fish.

Line selection is a balance between:

• Fish size

• Structure

• Water conditions

• Lure weight

• Casting distance

• Drag setting

• Abrasion

• Fishing technique

Common Inshore Line Sizes

For general inshore saltwater fishing, anglers commonly use lighter line for smaller fish and open water, while heavier line can be useful around structure and larger fish.

A simple starting point might be:

10–15 lb braid:
Light inshore fishing and open water.

15–20 lb braid:
A versatile range for many inshore situations.

20–30 lb braid:
Useful when fishing heavier structure, larger fish or tougher conditions.

These aren't rules.

Your local water and target species should determine what makes sense.

What About the Leader?

A leader is the section of line between your main line and your hook or lure.

For example:

20 lb braid → 20 lb fluorocarbon leader → jig head

The leader provides a different set of characteristics than your main line.

It can offer additional abrasion resistance and a different presentation around fish that may be wary of braided line.

Leader length and strength depend on the situation.

Choosing Line for Redfish, Trout and Flounder

For general inshore fishing, a medium-weight braided main line combined with an appropriate leader gives you a versatile setup.

Redfish

Consider stronger leader material when fishing around oysters, docks, rocks and other abrasive structure.

Trout

Lighter presentations and lighter leaders can be useful when fish are wary or you're fishing relatively open water.

Flounder

Pay particular attention to abrasion when fishing around structure and the bottom.

The important thing is matching the line to the environment rather than simply choosing the heaviest line available.

Fishing Line for Artificial Bait

Artificial-lure anglers often benefit from braid because of its sensitivity and relatively low stretch.

That helps you feel:

• The lure touching bottom

• A jig falling

• Grass grabbing the lure

• Structure

• Subtle strikes

A fluorocarbon leader can then provide the connection between the braid and lure.

For more on choosing lures, see our Artificial Bait for Saltwater Fishing guide.

Fishing Line for Live Bait

Live bait setups can be extremely simple.

A braided main line with an appropriate leader is one option.

Monofilament can also work well, particularly for anglers who prefer its stretch and simplicity.

The important thing is that the line matches your rig and target fish.

Our Live Bait for Saltwater Fishing guide covers shrimp, finger mullet, squid, worms, crickets and cut bait.

Don't Forget Your Knots

A great line setup is only as good as the connection between the lines and terminal tackle.

Important connections include:

• Main line to leader

• Leader to hook

• Leader to lure

• Line to swivel

Learn a few reliable knots and practice them before you get on the water.

A strong knot tied correctly is far more useful than knowing twenty knots poorly.

The Simple Beginner Setup

If you're just starting saltwater fishing and want to keep things simple:

Spinning reel → braided main line → fluorocarbon leader → jig head or hook

That setup can handle a wide range of inshore fishing situations.

From there, you can adjust your line strength and leader based on the fish, structure and conditions.

Final Thoughts

Fishing line doesn't need to be complicated.

Start by understanding three things:

Braid is a versatile main line.

Mono is simple, affordable and forgiving.

Fluorocarbon is an excellent leader option for many saltwater situations.

Then choose your pound test based on the fish and environment you're actually fishing.

Don't automatically use the heaviest line you can find.

And don't choose the lightest line just because it casts well.

Match the line to the situation.

That's Fishing Line 101.
