How to Buy the Best Monofilament Fishing Line

Let’s discuss some of the essential features of monofilament line to help you evaluate the best product of all.

1. Line Strength

The meaning of strength with monofilament lines depends on a variety of factors. Ideally, it is the line’s tendency to hold a certain amount of weight will declare its strength. In other words, the amount of weight it can handle before it snaps.

If you have noticed the table above, there is a specification used “Test LB”. You can determine the strength of a particular line from there as well.

It is measured in pounds and as the line’s tendency to hold more weight increases, its strength also increases. For example, the Berkley Trilene Big Game monofilament fishing line has the tendency to hold up to 800-pounds of weight. It is surely one of the strongest lines on the market.

Then the other key factor to consider in this aspect is that while catching a heavy fish, it is important that you buy a monofilament line with high shock resistance because in the alternative case, it line will snap easily if fish made some rescue attempt.

On the other hand, if you are simply planning to catch the controllable and easy targets then a line with less shock resistance will also do.

Now, the last thing is that not all lines are suitable to be used in all kinds of waters so make sure to get a dedicated product for optimal usage.

 The KastKing Mono-YE-500-4-P monofilament fishing line is one of the best monofilament fishing lines for saltwater as the abrasion-resistant line has low limpness and good retrieval.

2. Diameter

The width of a monofilament fishing line is known as its diameter. It is measured in millimeter or inches. The smaller fishing line diameter is considered to be better than a large diameter. However, one of the biggest pitfalls of small diameter is that knots cannot be prevented.

The smaller diameter will mean that the line will have lower stretch, less visibility, will be able to sink faster, and be better at luring action.

 The SeaKnight Monster Blade monofilament fishing line comes in a variety of diameters with the smallest starting diameter of 0.1-millimeter. It is a suitable product for those who are searching for the thinnest monofilament.   

3. Stretch

It is important to find a lowest stretch monofilament fishing line because such lines will cause less vibration in the water when fishes strike.

It is a common misconception among the buyers that lines with high stretch are better in flexibility and will bend without breaking. However, too much stretch can also be bad for the overall fishing experience as the line will lose sensitivity between the rod tip and the lure.

While selecting the right stretch, you should focus on the kind of fishing you plan to do. Mostly, people drop the bait in the water and wait for the bite. In this case, a line with high sensitivity is required. This means that you need a line with low stretch.

On the alternative case, if you are aiming for the top water fishes then a high stretch line will also work. It will handle the strike’s shock effectively.

Every fishing method needs a different line. You should pick a line that give better balance of rigidness and stretch.

4. Memory

The line’s memory is another crucial feature to focus because it will deeply impact your fishing experience. If we put it simply, a line with low memory is better than the one with high memory.

It is very difficult to cast a high memory line as it is likely to tangle on the reel. Also, when you have to sink the like to lure the fishes, you expect it to sink inside the water without any problems instead of floating.

The high memory lines are not able to stay inside the water. They are prone to float and twist. Therefore, you are recommended to pick a monofilament line with low memory.

5. Color

The ideal monofilament line is the one that is almost invisible. You can find a variety of lines that are available in clear color to ensure a variety of usage.

However, when you are fishing in clearwater, a high-visibility line helps the fisherman to check for the fishes inside the water.

There are also some lines that comes with glow feature i.e. the line glows in the daylight. Although these are clear lines but with glow feature, the fisher can see the target inside the water. One of the best recommendations of such lines is the Stren Catfish monofilament fishing line.

6. Abrasion-Resistant

Abrasion is caused on the line when it is rubbed against the rocks and other rigid objects inside the water. It is very important to look for a line that is highly abrasion resistant because fishes can be very damaging sometimes.

If you are casting a monoline for an aggressive fish then make sure to pick a highly abrasion-resistant monofilament line.
