Monofilament doesn"t have a set expiration date, and replacement frequency depends on how you use it. For example, heavily used lines, like those for deep water drops, experience more wear and tear. Replacing them every 1.5 years is a good rule of thumb.
Rough conditions like strong currents, heavy winds, or battling large fish can damage your line. If you encounter these, cut about 8 inches above any damaged areas to ensure optimal performance.
Regularly inspect your monofilament fishing line for signs of weakness or damage, like nicks, frays, or fading colour. Forming a routine helps you ensure your gear always performs well in casting accuracy, strength, and overall reliability.
