Best Fishing Line for Trout Reviews

1. Seaguar STS Fishing Line

The very first product on our list is the Seaguar STS Fishing Line.

This fishing line is one of the fiercest allies you can have when you’re fighting with various kinds of fishes on the sea.

The Seaguar STS Fishing Line is the jaguar of the sea that can handle the biggest catch you can possibly get.

With your strength and this fishing line’s durability, you’ll be the talk of the town.

Product Highlights

Seaguar is a company that manufactures fishing lines in the USA market.

The term STS stands for salmon, trout, and steelhead.

As such, the Seaguar STS Fishing Line is one of the few fishing lines made for a select group of fish species.

This means that if you’re fishing for trout, salmon, or steelhead, you can expect the best from the Seaguar STS Fishing Line.

It is made with fluorocarbon leader material, which is perfect for fishing.

This fishing line is developed through research and multiple tests to provide a paramount performance in terms of virtual invisibility, strength, and abrasion resistance.

When faced with a considerable amount of impact, this fishing line’s knot strength can absorb it effortlessly.

On top of that, it is a fast sinking line that will help you get to the strike zone faster.

The Good

One of the first things you’ll notice about the Seaguar STS Fishing Line is its fluorocarbon coating.

With this species-specific quality, it makes this product an excellent option for trout fishing.

You also don’t have to worry about availing one because it ships anywhere in the USA.

The fast sinking quality of the Seaguar STS Fishing Line also helps in making sure that you don’t have a hard time reeling your catch in.

The Bad

Although the fluorocarbon coating is an excellent material for trout fishing, it doesn’t necessarily mean that it’s a great option for other types of fishing.

Being species-specific is the downside of the Seaguar STS Fishing Line, which is not performing with the same paramount performance with other species.

In addition to that, the Seaguar STS Fishing Line is only 100 yards long.

This distance is fine with normal fishing, but if you intend to fish in deep waters, you may need a longer one.


  • Durable
  • Trout-fishing specific
  • Fast sinking line
  • Abrasion resistance


  • May not be a great option for other types of fish
  • Does not ship overseas
  • 100 yards long only

2. KastKing FluoroKote Fishing Line

The next item on our list is the KastKing FluoroKote Fishing Line.

The intelligent design of this fishing line is the product of state-of-the-art technology and remarkable innovations in the world of fishing.

Made by a company brand that won the 2015 ICAST (International Convention of Allied Sportfishing Trades) Award, the KastKing FluoroKote Fishing Line is something you don’t want to miss.

Product Highlights

The FluoroKote Fishing Line is a product released by KastKing last 2016.

With their previous best-seller, the KastKing Copolymer Fishing Line, they further developed it by adding a fluorocarbon layer of coating, giving birth to the FluoroKote Fishing Line.

That said, this fishing line has both the qualities of a copolymer and a fluorocarbon material.

The diameter of this fishing line is quite thinner than its copolymer counterpart, which makes it practically invisible when underwater.

The low absorption capability of this line also helps in sinking the line faster.

On top of that, it’s at least 300 yards long, which is great for fishing in deep bodies of water.

The Good

Right off the bat, one thing that will really impress you about this product is how the company developed it by combining their copolymer material with a one-hundred percent fluorocarbon coating.

Thus, you can expect the KastKing FluoroKote Fishing Line to have excellent copolymer castability and superior fluorocarbon invisibility.

Despite its reduced visibility, the density of this fishing line is still higher than some of the other products.

With this high density comes strength, low stretch, and optimum abrasion resistance.

The durability is further improved by the fact that this fishing line is versatile, allowing you to use it in different fishing methods.

The Bad

Probably the main concern you may have with this product is its diameter.

Although it does really help with reducing the fishing line’s visibility, thin lines may be a deal-breaker for some people.

Despite the advantage of giving you a greater capacity for reeling, other people just prefer a thicker line for the comfort of knowing your line is exceptionally durable for a heavy catch.


  • Brand won the ICAST Award in 2015
  • Copolymer plus fluorocarbon qualities
  • 300 yards long
  • Durable


  • Some people may find its small diameter not good enough for big fishes
  • More prone to entangling
  • Not species-specific; may perform well on one fishing method and not the other

3. Berkley Vanish Fluorocarbon Fishing Line

If you’re one who spends the weekend by testing your strength against big fish, the Berkley Vanish Fluorocarbon Fishing Line should be a top item on your checklist.

Developed by a company named Berkley, the Vanish Fluorocarbon Fishing Line is one of the many remarkable fishing tools on their arsenal.

Product Highlights

The Berkley Vanish Fluorocarbon Fishing Line is a 110-yard fishing line that combines the meticulous manufacturing process and practicality.

The fluorocarbon material integrated into these fishing lines is a remarkable breakthrough achieved by a series of tests and planning.

With its fluorocarbon finish, this fishing line is practically invisible underwater, and you’d definitely know you caught a fish because of its bite-sensitive quality.

It’s only three by one by three inches and weighs a total of approximately 1.6 ounces.

The low-memory line absorbs shock well, giving it a significant amount of strength for reeling in a catch.

The Good

What we definitely love about this product is that it’s made by a company that employs scientists to test their product and develop better results.

The Berkley Vanish Fluorocarbon Fishing Line spent some time under a microscope to ensure that its molecular structure can withstand a considerable amount of force.

Even though it’s exceptionally lightweight, the strength of this fishing line is undoubtedly great, even when underwater.

The fluorocarbon material makes it even better because a fish can’t practically see it, leaving its guards open.

The low-memory quality is also a great touch that makes reeling or casting it extra smooth.

The Bad

In the essence of fairness, what we saw on the other side of the table is that the Berkley Vanish Fluorocarbon Fishing Line is only 110 yards long.

Although it is indeed longer than some fishing lines in the market, using it for fishing in deep waters may not be a great idea.

Aside from that, it’s not species-specific, and since we're looking for a line that is great for trout fishing, we can’t definitively say that it will perform on an optimum level.


  • Tested by scientists
  • Lightweight
  • Durable
  • Sensitive


  • Not species-specific
  • 110 yards long only
  • Some people may find lightweight materials weak

4. P-Line Fluorocarbon Fishing Line

Made by a company that specializes in fishing lines and other fishing tools, the P-Line Fluorocarbon Fishing Line is one of the company’s leading products in making sure you get to improve your bite ratio.

Make sure not to miss out on the biggest catch with this product!

Product Highlights

The P-Line Fluorocarbon Fishing Line weighs only around one pound.

It’s made with Japanese fluorocarbon crystals, which allows it to refract light once it goes underwater, reducing its visibility.

Getting the P-Line Fluorocarbon Fishing Line means you’re getting 250 yards of knot strength and low stretch factor. It’s also abrasion-resistant and reduces water absorption.

The Good

When a manufacturer specializes in one product, you’ll know that a lot of effort was put into the development of it.

This is why the P-Line Fluorocarbon Fishing Line is a great addition to your arsenal.

It is a great option both for shallow and deep fishing.

Every angler who knows their way around fishing also knows that Japanese fluorocarbon crystals can guarantee that your fishing line does not scare the fishes because it’s almost virtually invisible.

Equipped with great knot strength and a low-stretch factor, the P-Line Fluorocarbon Fishing Line is sensitive enough to let you know when a fish bites.

The Bad

One thing we’ve noticed in the P-Line Fluorocarbon Fishing Line is that it’s not species-specific.

Although that’s fine with fishing in general, we strongly feel that having a fishing line that targets a specific fish, trout in this context, would perform better.

Aside from that, people from other parts of the globe may have a hard time getting their hands on it since it does not ship internationally and is available only in the USA.


  • Made with Japanese fluorocarbon crystal
  • 250 yards
  • Great knot strength
  • Low to no visibility


  • Not species-specific
  • Does not ship internationally
  • Some anglers do not prefer lightweight fishing lines

5. Trout Magnet SOS Fishing Line

The fifth and final product on our list is the Trout Magnet SOS Fishing Line, a product made by a company that specializes in manufacturing various fishing tools. Whether you’re a pro at fishing or just want something exciting to do for vacation, the Trout Magnet SOS Fishing Line will help you do the job!

Product Highlights

Weighing in at around 2.4 ounces, the Trout Magnet SOS Fishing Line is a product made with copolymer material.

At 350 yards, this fishing line is extremely durable and has optimum stretch resistance.

It’s also finished with light green shading, which makes for an excellent camouflage underwater. The Trout Magnet SOS Fishing Line ships anywhere in the USA, and is also available in some select countries.

The Good

The Trout Magnet SOS Fishing Line boasts a copolymer material, which means that it’s fairly easy to cast and reel.

Another characteristic of fishing lines made with copolymer is their resistance to abrasion and remarkable stretch despite their lightweight quality.

At 350 yards, the Trout Magnet SOS Fishing Line is a great option when you’re fishing in deep waters, and even in shallow ones.

The Bad

Despite the strength and optimum quality provided by the copolymer material, the Trout Magnet SOS Fishing Line does not have fluorocarbon characteristics.

Even though its green shade camouflages it nicely underwater, we all know that an invisible fishing line made with fluorocarbon material would still be the better option.


  • 350 yards
  • Copolymer material
  • Green shade


  • Some people prefer invisible lines instead of camouflage green shaded ones
  • May be great for trout fishing, but not for other types of fish

Buyer’s Guide

Since the fishing line is the only thing between you and the fish, you have to make sure that it’s strong enough to withstand an enormous amount of force.

There are lots of factors that affect your decision when buying a fishing line.

It may be the availability of the product, the brand, or lots of other aspects.

Here are some things you need to look out for when buying a fishing line.

1. Type

There are three main categories when it comes to fishing line, namely, braided, monofilament, and fluorocarbon.

The braided fishing line doesn’t have much stretch to it, which means it’s also one of the strongest fishing lines that can withstand the heaviest types of fish.

The monofilament, from the term mono, is a fishing line made from only one type of material with varying thickness.

The fluorocarbon fishing line, although made from a single type of material, is a lot denser than a monofilament line, making it stronger than the former.

2. Strength

Another thing you have to take note of is the strength of the line you’re using.

One of the worst feelings is knowing that your hook has got a good grip on a fish, but your line suddenly breaks from the pressure.

You can determine the strength of a line by looking at an indicator on its packaging.

If you see a 40lbs sign on it, that means it can lift up to 40lbs of weight.

3. Color and Visibility

Lastly, you surely want to take note of your line’s visibility.

Thick fishing lines are great for lifting a lot of weight, but on the downside, they are often quite easy to spot, which can scare a fish.

On the other hand, thin fishing lines are almost invisible, but they sometimes break when your catch is too heavy.

Make sure that you find the sweet spot where your line is strong enough but not visible.

You can often get this in the material it’s made with.


1. What Is the Best Line Weight for Trout Fishing?

Having the best setup is essential in trout fishing, which is why anglers pay close attention to their fishing line’s weight.

With that in mind, the best line weight when fishing for trout is somewhere around 1.75 pounds and 8.5 pounds.

Depending on the size, fishing lines of these weights can withstand various sizes of trout.

2. What Line Do You Spin Trout On?

There are two main categories when it comes to fishing reels, and they are casting reels and spinning reels.

That means the fishing line you’re using should be compatible with your reel.

When it comes to spinning reels for trout, you want to be as discreet as possible.

This makes the fluorocarbon lines the best option for spinning reels because of its almost invisible quality as it refracts light underwater.

With a fluorocarbon fishing line, you can sneak closer to a fish without it noticing.

3. What Is the Best Thing to Catch Trout With?

Trout has an extensive range of diet, which means lots of bait types are great options for trout fishing.

With the trout’s appetite, insects are definitely on the list of the baits you can use.

Other baits such as the rebel-wee crawfish, minnows, and even fish eggs, make for great baits as well.

Then again, you can never go wrong with buying market-produced fish baits.

Just make sure you inform them you’re fishing for trout.

4. What Size Line Should I Use for Trout?

Once you’ve figured out the weight of the fishing line you’re supposed to use, you should also think of the size of the line you’re using.

Perhaps one of the many reasons why trout fishing is very popular is that they’re quite easy to find.

There are lots of types of trout, and they can grow in a wide range of sizes.

With that in mind, trout can be found in almost all kinds of bodies of water.

Rivers, lakes, ponds, and even oceans, all stand home to trout.

That’s why the size line used for trout fishing is debatable.

A 100-yard fishing line will do just fine in a river because trout tend to run up and down the water.

On the other hand, if you’re fishing in deeper waters, you may want to go for longer fishing lines.

5. What Time of Day Is Trout Most Active?

As we’ve mentioned, your summer would be best spent in trout fishing.

Not only do you get to experience to be one with nature and avoid crowded beaches, but also because trout are most active during the warm seasons.

On the contrary, the time of day to go fishing for trout is also important.

As mentioned, trout have an enormous appetite, making their diet quite varied.

Since insects are also part of their diet, fishing for trout would be best at the time of day when bugs, mosquitoes, and other insects are active as well.

That said, whenever you head out for trout fishing, the best time would be in the afternoon to early evening.

That’s because this is the time of day where lots of insects go out and head to the waters, which means trout would also be looking for their food.

Final Verdict

When going on a fishing trip, there are lots of things that you have to consider.

The line's size and weight work better depending on what fishing method you’re using or what you are fishing for.

Of all the fishing lines listed here today, we’ve come to the final verdict as to which is the best fishing line for trout.

We took into consideration the size of the line, the material it’s made with, and lots of other factors.

We strongly feel that the best fishing line we have here today is the KastKing FluoroKote Fishing Line.

Strength, Stealth, and Invisibility

Although you may find the same copolymer material found in the Trout Magnet SOS Fishing Line, the KastKing FluoroKote Fishing Line significantly won the battle as it combined the advantages of the strong copolymer and the invisible fluorocarbon.

Not only is the KastKing FluoroKote Fishing Line as strong as the Trout Magnet SOS Fishing Line, but it’s also as stealthy as the other fishing lines on our list.

Length and Recognition

Although it’s not species-specific, the fact that the KastKing FluoroKote Fishing Line is three hundred yards long would still make it a great choice for trout fishing since you can find this species in nearly all bodies of water.

With the KastKing FluoroKote Fishing Line's length, you don’t have to worry about whether you’re fishing in a river or a lake

To top it all, the KastKing FluoroKote Fishing Line is the only fishing line in our list that is manufactured by a brand that won an award.

That is a testimony as to how much effort and thought are put into creating this piece of equipment.

With that, we wish you a great vacation and lots of catch!
