Monofilament fishing line is an extremely popular choice for different types of anglers worldwide. It doesn’t matter if an angler is spinning for predators, trawling in saltwater, or coarse fishing, there is an extremely high chance that that fisherman is using monofilament – but why?

What makes monofilament so popular and good for such a diverse range of fishing purposes? In this article, we will be looking at the qualities of monofilament line, what makes it so popular, and why it is the perfect choice for your spinning reel.

In this article, we will be answering all the questions you may have about monofilament line and going over exactly why it is the best choice for your salt and freshwater spinning ventures. We will also be reviewing the best monofilament line for all types of spinning and trawling.

This is a line that I have used for a large percentage of my fishing career and still use today when spinning for predators and catching huge sturgeon and catfish in Europe. Without further ado, let’s take a look at some of the qualities of monofilament fishing line.

What Are the Qualities of Monofilament Fishing Line?

There are many benefits to using monofilament line and since it was developed in the 1950s it has overtaken sales of braid dramatically. Monofilament line is made by melting synthetic polymers and stretching the material while in its melted state through small holes. This then forms thin strands of line that is spun onto spools for commercial sale.

The size of the holes that the polymer mixture is stretched through will determine the gauge of the line and ultimately its final breaking strain. Wider holes produce thicker gauges and smaller holes thinner ones, with thick gauges boasting stronger breaking strains and thinner boasting low-visibility but also lower breaking strains.

Monofilament fishing line is synthetic which makes it incredibly resistant to constant use in saltwater and freshwater alike. Being a synthetic fiber means that it is not susceptible to rotting or losing strength value over time when it is left wet, this is an extremely good quality to have in a fishing line as it will last for long periods of use and storage without degrading.

Mono fishing line is flexible in its nature which gives a certain amount of stretch before breaking. This makes it perfect for fighting large game fish and hard-fighting predators because it puts a buffer between your rod and the fish. This quality means that there is a bit more room for error when playing a fish and if you are fighting a little too hard and the fish pulls back that flex should prevent a hook pull, snap out, and ultimately a lost fish.

Monofilament line is almost invisible in the water especially in smaller gauges which is a big benefit to you as you will not have to worry so much about the cost of leaders and low-visibility hook links as you would with braided line. The low-vis qualities of monofilament could also help you catch more fish and hook into those more finicky feeding and wary fish. Fish aren’t as stupid as some of us may think and fish that have been hooked before can certainly notice a fishing line, mono gives you the chance to go unnoticed and hook up to those clued-up fish.

Due to the materials and manufacturing process of monofilament line, it is extremely cheap compared to braid and fluorocarbon mainlines. This means you can change it more often and it will not break your bank account every time you need to spool up your reel with yards and yards of new line!

Mono fishing line is extremely abrasion resistant as well which is why I personally use it for targeting bottom feeders like the sturgeon pictured above (caught on Berkley Big Game Trilene Mono). When a big fish takes you for a ride along underwater bankside vegetation, through lily pads, or along a rocky shoreline you still have a chance of landing it without the line snapping under tension. This has saved me many times in my fishing career, and I have been shocked after reeling in some colossal fish that the bruised line still functioned and put the fish in the net!

Overall, Monofilament line is an affordable fishing line that will help you land anything from bass in freshwater to Tarpon in saltwater with ease. It is abrasion-resistant, almost invisible in the water, strong, durable, and provides a buffer between you and the fish that could potentially save you from a lost catch. Braided lines certainly have their place in the world of fishing, but for day to day fishing, monofilament is what my and many other angler’s reels are spooled up with.

The Best Monofilament Line for Your Spinning Reel

So, what is the best monofilament fishing line for your spinning reel? Earlier I mentioned that I landed the sturgeon in the picture above using Berkley Big Game Trilene Mono. That Sturgeon weighed 135-pounds (61 kilograms) and it was landed after an immense fight using Berkley’s Trilene in 30lb breaking strain. Due to the extensive amount of large fish over the 60kg mark that I have successfully landed using this line I really cannot recommend anything else, so the Trilene is the line we will be reviewing today.

The Berkley Trilene Big Game Monofilament Fishing Line

  • Offers ultimate shock resistance
  • Is abrasion-resistant
  • Exceptionally strong
  • Perfect for big fish in salt and freshwater
  • Outstanding knot strength
  • Extremely cost-effective
  • Available in a wide range of breaking strains
  • Plenty of length options to ensure you only buy what you need


Berkley was founded by a very young Berkley Bedell (16 years old to be precise) in Iowa in 1937. This young lad started a business with 50 dollars that he earned from his paper round and originally started selling hand-tied flies to fishing tackle shops and anglers around the area. It all started from his bedroom in the family home using materials that he could find cheaply or for free, he even tied flies using the hair from the family dog!

After Berk Graduated school in 1939, he was employing people to tie flies in the basement of his parent’s house. The business soon outgrew the basement, so he took over the living room (to his parent’s annoyance) and as demand grew even more, he expanded to the second floor of his local grocery store. Berk then attended university and served in the military. He then returned to his hometown in 1945 to pursue his business and it was at this time that Berkley as a brand and company was founded.

I felt I had to tell this story as this company was founded by a boy with a passion and a dream that he turned into a reality. Berkley is almost the definition of the American dream and shows how a simple idea, motivation, and some hard work can pay off!

Anyway, now we have discussed the history of this fantastic company let’s go over why this monofilament line is the best choice for you and your spinning reel. The Trilene mono mainline is one of the most popular monofilament fishing lines in North America and it is renowned for its incredible strength, abrasion-resistance, and excellent value. This line holds superior strength throughout its length and retains incredible knot strength. You can put confidence in this line and know that it will help you put fish of all sizes on the bank and in the boat.

The Berkley Big Game Trilene fishing line boasts incredible strength across their range of gauges and breaking strains, so you can have just as much confidence when fishing for small predators with 8lb line as well as large game fish with 130lb line. This line comes in a range of gauges and breaking strains with each one being offered in varying lengths. You can buy the exact amount that you need rather than wasting money on heaps of line or falling short when you are spooling up a reel with fresh line.

If you are looking for quality for a great price, then look no further. Tight lines, and happy fishing!
