Everything You Need To Know About Fishing Lines

Fishing line quality

Before explaining in detail the types of fishing lines and their different uses, we have to emphasize their quality. Luckily, determining the quality of a thread is quite simple, this is quickly seen by understanding the memory and flexibility of Nylon .

When we speak of memory we refer to the ability of the line to return to its original shape . That is, if when unscrewing it from the coil it stays wound, that means that it has little memory, on the other hand if it is kept straight the memory is high. In short, if you want quality, it is better to buy a nylon with a low memory.

How to distinguish if the thread has high or low memory without unwinding it? It is quite simple, the brightness of it usually also determines the quality of the line, if it shines a lot it is a sign of a high memory, if it shines little it means that it has a minimum memory and higher quality, also if a fishing line does not shine too much it means that it can go unnoticed under water.

Another factor to take into account in the quality of the line is its elasticity . A thread that is too elastic can make it difficult to pin the fish, while a very stiff thread could be cut by opposing forces during retrieval.

Fortunately, you don’t have to go around too much to find them, as most lines made especially for fishing come at 50% elasticity.

The measurements of the fishing lines

Not only do lines have a certain distance, but their thickness also determines their resistance. This is measured in millimeters (mm) ranging from 0.10 to 0.80 approximately, depending on the manufacturer.

At greater thickness, the line can withstand greater forces and weights, that means that if the dam exerts a greater weight than the resistance of the line, it will break.

To get a clearer idea, a thread of medium thickness (0.35 mm) can support up to 7 or 8 kilograms of weight.

The colors of fishing lines

From sheer to multiple colors in the same line, fishing lines come in different presentations to give your clients variety.

Many fishermen prefer that their strings go unnoticed by their prey, hence they prefer invisible green or blue strings to blend in with the sea and algae.

Others, on the other hand, want to attract the attention of the most curious fish with red, orange and yellow threads. Depending on your needs you can choose any color you like.

Types of fishing line

Going into the matter of special characteristics, it is necessary to subdivide the categories of fishing lines, each type has qualities necessary for one style of fishing or another, and even for the type of prey or the area where you are going to fish.

Monofilament Thread

They are those made of a single artificial polymer called polyamide, they stand out in the market for coming in different color presentations, with green, blue, red, and yellow being the best sellers. However, some are tinted in up to three different colors. They are used especially in cloudy or algae-filled areas because they do not get too tangled. In this range we also find the floating nylons that are hollow inside, making the air help them to float and provide power when diving.

Braided yarn

Instead of using a single strand, the braided yarn is made up of several strands of different compounds, thus gaining balanced flexibility and strength.

Fluorocarbon thread

Fluorocarbon is a material used to give the line the power of invisibility under water. Some monofilament yarns have fluorocarbon coatings to enhance their qualities but will never compare to the strength of a full fluorocarbon. That is why they are used more for joints than for the mother line.

Unifilament yarns

Although they also use a single strand to reduce their diameter, these fishing lines are usually very resistant and efficient for small prey that have a lot of speed and strength when swimming or those that are at great depths, since they usually come in extensive presentations (1000 to 3000 meters)

Tail of rat

It is a line that has two gauges and is used especially for fly fishing. The first part of the line (backing) is used for casting and sinking, the second part (flyline) is where the fly goes. The thickness of the rat tail decreases as it approaches the tip.


It is a type of braided wire especially used in boat fishing, it has a large number of strands, but maintains a tubular structure, (hollow) to provide an advantage in the collection.


It is a large diameter monofilament used for large dams, its memory is quite high. But it is counteracted by the lead and the strength of the fish when putting up resistance.

How to put the fishing line on the spool

If you bought your spool in our store, or another store that offers the winding service, you probably did not have the opportunity to learn how to put the fishing line on the spool. Although it is a simple task, it is recommended that you know how to do it and practice it every season to prevent the thread from getting tangled and always wearing out in the same place.

How to put the fishing line on the spinning bobbin spool

Before starting; Check that the bobbin on the spool rotates in the same direction in which the thread is to be unscrewed from the packing. If it doesn’t, then flip the gasket (plastic spool). Thread the thread on the main ring and using a firm knot but not thick; Tie the thread on the spool’s bobbin and make sure the knot doesn’t slip when you turn the crank. Then close the bobbin and start winding.

You can use a cloth to hold the thread and wrap it tightly. This way you can turn the crank much faster. Cut the line once the thread is half an inch from the edge.

How to put the fishing line on the bait casting reel

Thread the bobbin into a thread station, or at any rate use a pencil and ask someone else to hold it. It stretches the thread over the top of the bobbin and allows the spool system to pick it up and wind it one turn. You can use an adhesive tape so that it does not come off and then remove it to continue rolling evenly. Turn the crank to fill the spool capacity and cut the thread.

How to care for fishing lines

Maintaining and cleaning fishing lines is an essential part of the day if we want it to last and function properly. Here are some tips to take care of your fishing lines and keep them looking like new.

  1. Never leave the fishing lines in the sun. Direct heat causes the material to dry out and become brittle, the same happens if it is subjected to sudden changes in temperature.

  2. Please wash them after use. Especially if you practice surfcasting; since the saltpeter is extremely corrosive and weakens the fibers along the entire length of the line. A very simple and easy trick to clean them is to make a very long cast with a good weight sinker to get the maximum line capacity possible. Then while the fishing line is being collected you can tell someone else to wet the reel with a jet of fresh water. This way you will clean the entire line and not just the surface parts.

  3. Mount the spool thread upside down. Although it is a bit tedious to execute, this simple trick will allow you to take advantage of the other end of the thread that always remains threaded on the spool. To do this, you must wind the thread on a spool, then pass it to another spool and from that last spool, wind it again on the spool.

  4. Load your spool with new thread before the old one ruins your day. Although we want to make the most of our lines, it does not mean that we fish with a line in terrible conditions due to the wear and tear of several days, buy a new one each season so that your performance is not affected.
