Imagine that you’re out fishing and you feel a big fish tug the end of your fishing line. As you try to reel it in, the line broke and the fish got away.

Seem familiar? This is actually nothing new and occurs to anglers when they haven’t invested in good fishing lines. So you ask, which is the best mono fishing line?

For starters, the monofilament fishing line is a fishing line made from a single fibre of plastic. Most people nowadays opt for mono fishing lines because they are cheaper to produce and their different range of diameters have varying tensile strengths.

The best monofilament fishing line would ensure that your line is strong and has the strength to bring up a large haul of fish without breaking.


Every angler knows the importance of a good fishing line. It is not only an essential part of the fishing rod but also important to provide steady support when fishing. It is, therefore, always a wise decision to invest in a good fishing gear.

You can always shop for monofilament fishing lines within a budget and they would still provide you with the best quality, so you shouldn’t worry if you cannot afford a really expensive line.

Monofilament fishing lines are so easy and cheap to produce, and yet are the best in the world when it comes to line strength.

Depending on the size of your line and its line diameter, you can actually go for bigger catches without your line giving up. However, with so many types and brands of mono fishing lines, it’s difficult to find yourself the best one.

You also would need to look into the various factors which go into choosing the best. So to help narrow down your search, a few factors have been mentioned below:

Factors To Remember Before Buying the Best Mono Fishing Line

Understanding Fishing Line Strength

A good fishing line comprises a lot of factors and the most important one is choosing the right pound test. For those who don’t know it yet, fishing line strength is called a ‘test’ and is measured in pounds.

Each spool of the fishing line would consist of a label denoting what its pound is. A pound test is basically a measurement of how much stress can the fishing line hold before it breaks. This determines the kind of fishing plans that you decide on, and so you must make sure that you shop accordingly.

Choosing The Correct Fishing Line Weight

If you’re someone who’s interested in fishing or has even a little keenness towards it, you would already know the importance of choosing the correct weight when you’re planning a fishing trip.

The fishing line should match the fish species that you plan on catching, the areas you fish in, or how you plan on catching them. The right weight not only complements the weight of the catch but also provides stability when holding on to it before bringing it in.

Heavier fish species like Bass or King Salmon might need stronger fishing lines. A few factors you should remember when purchasing a fishing line would be:

  • Select the target species: You should decide what you are fishing for. What fish species do you hope to catch? These are the initial questions that would pop up in your mind. Based on these alone, you can decide upon the strength and subsequently the trip. Saltwater species like Redfish would require different features of a fishing line than what you generally use for casting panfish. Heavier catches generally demand a stronger line capable of bearing excess amounts of weight rather than ordinary lines used for smaller fishes.
  • Area of fishing: If you’re fishing in heavy waters or larger water bodies, you might need a different fishing line pound test that can fare better in rough waters. Fishing in small water areas like ponds doesn’t require much and you can even opt for ones which are lighter and quick to pull.
  • Weather Conditions: Weather conditions always play a major role when fishing. Varying elements decide the pound test required for the species of fish that you wish to catch. Pleasant weather is always preferred as compared to stormy weather, where the waters may be rough and the fishing line, therefore, needs to be quite strong.
  • Fishing according to your gear: Most fishing gear that you own, like rods and reels, have a number of weights assigned to them. Their weight also plays a deciding factor in choosing your fishing line. It will clearly be unwise of anyone to use a stronger or longer-diameter fishing line for a comparatively smaller or lighter rod or fishing reel.

Shopping for something like a fishing line is not easy. Fishing enthusiasts and beginners alike always have to go through certain factors or features that they would require from their fishing line.

Being such a complex issue, you might get confused at times about what your preferred model should be able to do or the tensile strength that it should hold.

After you’ve decided what you want, you again have to go through the loop of choosing the manufacturer you want it from. So we have prepared a list which will aid you in your search:

Monofilament vs Fluorocarbon vs Braided Fishing Line

When you’re out shopping for fishing lines, it can get confusing to choose between the three types of fishing lines available. All three have their own set of pros and cons. So which one should you choose?

  • Monofilament – Monofilament lines are the most common and affordable ones at present. One of the major advantages is their slow sink rate, making them a good choice for topwater fishing. The built-in stretch also makes them easier for inexperienced anglers to avoid setting the hook too hard, which can cause the fish to come off the top. Some major drawbacks of this line include its lower resistance to abrasion and its reduced sensitivity to alert you when a fish latches onto the bait. It also displays higher visibility as compared to fluorocarbon, which might alert the fish as well.
  • Fluorocarbon – Fluorocarbon, as compared to monofilament, is more abrasion-resistant and is better for fishing in cover. The line is not visible to fish and has excellent sensitivity, alerting you when a fish takes the bait. They are also exceptionally strong and give you enough of a boost when you’re wrestling fish. These lines are built to last for years. One of the major drawbacks, however, is that fluorocarbons are more expensive than other lines and sink faster, hardly giving the fish any time to catch the bait.
  • Braided – Braided lines are popular among anglers due to a higher durability and strength-to-diameter ratio. Their major advantages include being smaller in diameter, a higher strength than the others with powerful hook sets, and excellent sensitivity. However, braided lines are quite expensive and more visible than fluorocarbon. Because of their slight rigidity, it’s harder to knot the line securely.

In most cases, people generally opt for either a monofilament or fluorocarbon and very few would choose braided fishing lines, the main reason being their use and efficiency in getting the better of braided fishing lines.

The most popular fishing line is the monofilament followed by the fluorocarbon. It is better to start off with monofilament fishing lines if you’re a beginner. They will help you familiarize yourself with fishing kits and gears and provide their fair share of knowledge when it comes to fishing.

If you’re already a professional in this field, you can opt for any fishing line without any worries.

Final Thoughts

When it comes to fishing lines, there are so many brands offering you more or less the same features with varying prices. So which is the best monofilament fishing line? Which one is really worth your money, and which one should you choose? All these questions might start running in your mind when you step out to purchase a fishing line.

Without knowing the factors involved when selecting a fishing line, it is obvious that anyone can get confused. So it is important that you research and check out the features and qualities that your fishing line should possess. Not only should it be durable and strong, but it must also maintain its sensitivity in order to alert you when a fish takes your bait.

Another important factor to be kept in mind is that you should always purchase according to your fishing requirements. If you prefer light fishing, then opt for a lighter fishing line best suited for the purpose.

But if catching big game is your main agenda, then look for fishing lines which are more on the heavier side so that they provide you with adequate strength against the fish.

Not choosing the correct pound test rating can be quite disastrous as the line may break if it’s not meant to lift more than the weight prescribed.

Always make sure that your fishing line is compatible with the rest of your fishing gear. That way, they will all complement each other and make your fishing trip all the more enjoyable and fruitful.

Aside from all the factors to keep in mind, you must also research and decide upon the type of fishing line that you prefer. If you’re a fishing enthusiast and okay with fishing in a cover, then fluorocarbon would be your best bet. Not only is it invisible when immersed in water, but is also super sensitive to touch, alerting you at the slightest of movements.

The invisible line makes it easier to trick the fish when latching on to the bait, and the strong line makes sure that you maintain your own against the fish.

Monofilament fishing lines are best suited for beginners who are willing to learn fishing. Because the line’s stretch is already set, it prevents you from adding on an extra line and makes it easy to handle. They are also a lot cheaper compared to fluorocarbon or braided fishing lines.

Most fishing lines are built to last you a long time and are quite durable. It’s not always necessary to purchase only the most expensive fishing lines as developers manufacture more products which can comfortably fit in your budget. Nowadays, even products within a budget provide you with the most efficient service.

Now that you know about the things you should look for in a fishing line, it becomes an easy process to go down to the store and pick one up. After all, no fishing trip can be complete without having all your fishing gear together!
