Importance of Testing Fishing Line

Testing your fishing line periodically helps avoid potential disappointments and ensures you’re well-prepared for your fishing trips.

A compromised line can lead to lost fish, tangled cables, and frustrating situations. Following the methods outlined in this article, you can determine whether your fishing line is still good or requires replacement.

Visual Inspection

The first step in testing your fishing line is conducting a visual inspection. Carefully examine the entire line length, looking for visible signs of wear, fraying, or discoloration. Check for any abnormalities, such as weak spots or thinning areas, which could indicate potential weaknesses.

Manual Inspection

Once you have completed the visual inspection, it’s time to perform a manual review. Run the line through your fingers, feeling for any roughness, bumps, or inconsistencies. A smooth and consistent texture indicates a healthy line, while roughness or irregularities may suggest damage or aging.

Performing the Overhand Knot Test

One effective method to assess the strength and durability of your fishing line is by conducting the overhand knot test.

Tie an overhand knot with a reasonable amount of tension and carefully examine it. If the knot holds tight without slipping or breaking, your fishing line is still in good condition.

Checking for Line Memory

Fishing lines tend to develop memory over time, especially monofilament lines. Line memory causes the line to retain its coiled shape, resulting in tangles and reduced casting distance.

To check for line memory, stretch a section of the line between your hands and observe if it straightens out quickly or retains its spiral shape.

Testing Line Strength

The strength of your fishing line is crucial for landing fish successfully. To test its strength, tie a secure knot to a fixed object and apply steady pressure while pulling the cord.

The bar still possesses strength and integrity if the cable withstands the force without breaking or stretching excessively.

Checking for Abrasions and Nicks

Inspect your fishing line for any visible abrasions or nicks. These imperfections weaken the line, making it prone to breakage.

Run your fingers along the line length, paying close attention to areas that might have come into contact with rocks, snags, or rough surfaces. If you feel any rough spots or notice any significant damage, it is advisable to replace the line.

Testing Knot Strength

Knots are essential for securing hooks, lures, and swivels to your fishing line. Weak or poorly tied knots can result in lost fish.

Test the knot strength by tying your preferred knot and applying pressure by pulling the cord. Your fishing line is reliable if the knot holds firmly without slipping or breaking.

Performing the Water Absorption Test

Some fishing lines, particularly monofilament lines, can absorb water over time, reducing strength and durability.

Performing the Water Absorption Test

To test for water absorption, immerse a section of the line in the water for a few minutes and then examine it for any colour, weight, or texture changes. If the line becomes noticeably heavier or weaker after water exposure, it might be time to replace it.

Evaluating Line Color

While the color of your fishing line may not directly affect its performance, it can indicate its condition.

Faded or discolored lines may have been exposed to excessive sunlight or chemical damage, compromising their strength. If your line exhibits significant color changes, replacing it with a fresh one is advisable.

Assessing Line Diameter

The diameter of your fishing line plays a crucial role in its performance. Over time, pipes can thin out due to wear and tear, impacting their strength and casting abilities.

Use a micrometer or a line diameter gauge to measure the thickness of your line at different intervals. If you notice significant thinning, it is a sign that the line may have weakened and require replacement.

Considering Line Age

The age of your fishing line can be a determining factor in its condition. Even if a line appears visually intact, prolonged use and exposure to the elements can degrade its quality.

It is generally recommended to replace fishing lines every six to twelve months, depending on the frequency of use and environmental factors.

Storing Fishing Lines Properly

Proper storage of your fishing lines is essential for maintaining their quality and prolonging their lifespan.

Avoid storing cables in direct sunlight or extreme temperatures, as these conditions can accelerate their deterioration. Instead, please keep them in a cool, dry place, away from direct sunlight and other potential sources of damage.


The above article explains How to Test if a Fishing Line is Still Good. In conclusion, regularly testing your fishing line is crucial for ensuring a successful and enjoyable fishing experience. By conducting visual inspections, manual examinations, and various tests, you can determine the condition of your fishing line and take appropriate actions, such as replacing it when necessary. Remember to store your lines properly and consider their age as well. Following these guidelines gives you the confidence to use a reliable fishing line on your next angling adventure.
