Is old fishing line on a spool still good?

Fishing line can degrade over time, regardless of whether it is on a spool or not. Here are some factors that can affect the longevity of fishing line:

1. Material: Different types of fishing line materials, such as nylon, fluorocarbon, and polyethylene, have varying lifespans. Nylon fishing line tends to degrade relatively quickly compared to fluorocarbon and polyethylene lines.

2. Exposure to Elements: Ultraviolet (UV) radiation from the sun, moisture, saltwater, and extreme temperatures can cause the fishing line to degrade over time. Leaving a spool of fishing line outdoors or exposing it to harsh conditions can accelerate the deterioration process.

3. Duration of Storage: The longer the fishing line has been stored, the more the degradation process will progress. Old fishing line, even if kept on a spool, can become weak and brittle.

4. Quality of Storage: Fishing line should be stored properly to prolong its lifespan. Keeping the spool in a cool, dry place, sheltered from direct sunlight, and preventing kinks or bends in the line will help maintain its integrity.

It's a good practice to regularly inspect your fishing line and replace it periodically, even if it is still on the spool. Signs of line degradation can include fraying, discoloration, a rough feel, or reduced knot strength. Using old or degraded fishing line can compromise your fishing experience and can even lead to line breakage during critical moments. For the best performance and reliability, it is recommended to use fresh fishing line for your fishing trips.
