The Basic Steps for Removing Old Line and Adding New

Replacing line on a spinning reel takes about 15 to 20 minutes and requires only a few tools: scissors or line cutters, your new fishing line, and optionally a line stripper or your fingernail. The process is straightforward: cut the old line at the reel, remove it completely, tie the new line to the spool using an arbor knot, and wind it on under tension until the spool is full.

You do not need to disassemble the reel or take it to a shop. The entire job happens at the spool itself, and you can do it sitting at a table or on your porch. The most common mistake is winding line on too loosely, which causes it to slip during casting or fighting a fish.

Key Takeaways

  • Cut the old line just above the spool and peel it away; do not try to unwind it all at once.
  • Tie new line to the spool using an arbor knot, which grips the spool and will not slip under load.
  • Wind line onto the spool under steady tension so it sits flat and does not bunch or spiral.
  • Fill the spool until the line is about one-eighth inch from the rim; too full causes casting problems, too empty wastes the reel's distance.
  • Test the line by pulling hard on it after winding; it should not slip or move on the spool.

Cutting Away the Old Line

Start by cutting the line just above the spool with scissors or a line cutter. Make one clean cut rather than sawing back and forth, which frays the line and makes cleanup harder. Once the line is cut, you can peel the old line away from the spool by hand. It will come off in loops and tangles—this is normal and takes less than a minute.

If the old line is stuck or wound very tightly, use a line stripper (a small plastic tool sold at tackle shops for a few dollars) or your fingernail to lift the edge of the line and peel it back. Do not try to unwind the entire spool by turning the handle backward; you will tangle the line and waste time. Once the spool is bare, wipe it clean with a dry cloth to remove any debris or old adhesive.

Tying the Arbor Knot

The arbor knot is the standard knot for attaching line to a spinning reel spool. It grips the spool and will not slip when you cast or fight a fish. To tie it, wrap the new line around the spool once, then tie an overhand knot around the standing line (the long part of the line coming off the spool). Tie a second overhand knot in the short end of the line, about two inches from the first knot.

Pull the standing line tight. The first knot will slide down and cinch around the spool, and the second knot will stop it from sliding further. Trim the short end close to the second knot with scissors. The knot should sit flat against the spool with no bumps or loose loops. If it feels loose when you tug the standing line, untie it and try again—a loose arbor knot is the main reason line slips during casting.

Winding Line Under Tension

Hold the line between your thumb and forefinger about six inches above the reel, explore steady pressure as you turn the handle. This tension keeps the line from bunching or spiraling on the spool. Turn the handle at a moderate speed—not so fast that you lose control, but fast enough that the line winds smoothly. The line should lay flat in neat, parallel rows across the spool.

If the line starts to bunch or spiral, stop and adjust your hand position. Move your fingers slightly closer to or farther from the reel until the line lays flat again. Keep the tension steady throughout; if you release pressure, the line will loosen and slip. Wind until the line is about one-eighth inch from the rim of the spool—close enough that you have good casting distance, but not so full that line spills off during a cast.

Checking Your Work

Once the spool is full, pull hard on the line with your other hand while holding the reel steady. The line should not move or slip on the spool. If it does, the arbor knot is loose or the line was wound too loosely. Cut the line at the spool, remove it, and retie the arbor knot, making sure it is tight before winding again.

Inspect the wound line for gaps, bunches, or spiral patterns. A small amount of unevenness is normal and will not affect casting, but large gaps or tight bunches mean the tension was uneven. If the problem is severe, rewind the spool. This takes practice—your second or third reel will look noticeably better than your first, and that is expected.

Choosing the Right Line Weight and Type

Spinning reels are rated for a range of line weights, usually printed on the spool or in the reel's manual. Common weights are 6-pound, 8-pound, 10-pound, and 12-pound test. Heavier line holds larger fish but casts shorter distances and is more visible in the water. Lighter line casts farther and is less visible but breaks more easily.

Match the line weight to the fish you are targeting and the reel's rating. A reel rated for 6- to 12-pound line should be spooled with line in that range. Monofilament is the most common choice for beginners because it is affordable, forgiving, and straightforward to tie knots in. Braided line is thinner and stronger but requires different knots and is more expensive. Fluorocarbon is less visible underwater but costs more than monofilament.

Common Mistakes to Avoid

The most frequent error is winding line too loosely, which causes it to slip during casting or when a fish pulls hard. Always maintain steady tension with your fingers as you wind. Another common mistake is filling the spool too full, which causes line to spill off during a cast and tangles the guides. Stop winding when the line is about one-eighth inch from the rim.

A third mistake is tying the arbor knot incorrectly or too loosely. Test the knot by pulling hard on the standing line before you wind; if it slips, untie it and retie it tighter. Finally, do not reuse old line. Even if it looks fine, old line loses strength over time and is more likely to break. Always start with fresh line when you replace the spool.

Frequently Asked Questions

How often should I replace the line on my spinning reel?

Replace the line once a year if you fish regularly, or whenever it shows visible damage like fraying, discoloration, or stiffness. If you fish only a few times a year, you can go longer, but line degrades in sunlight and heat even when not in use. When in doubt, replace it—new line is cheap compared to losing a fish.

Can I wind line onto the reel by hand without a handle?

Yes, but it is slower and harder to maintain even tension. You can turn the spool by hand while holding the line tight, but using the reel handle is faster and gives you better control. If your reel handle is broken, have it repaired before replacing the line.

What do I do with the old line after I remove it?

Old fishing line is not recyclable in most curbside programs and can tangle in wildlife, so do not throw it in the trash or leave it on the ground. Many tackle shops and fishing clubs collect old line for proper disposal. Check with your local shop or search online for a line recycling program in your area.

Do I need to soak new line before winding it on?

No. Some anglers soak line in water for a few minutes to make it more pliable, but it is not necessary. Monofilament line works fine straight from the spool. If you do soak it, let it dry completely before storing the reel, or it may develop mildew.

What if my reel will not hold enough line at the weight I want to use?

Use a lighter line weight that the reel is rated for, or back the spool with a thicker filler line before winding on your main line. Backing is a cheaper, thicker line that fills the spool first, then your main line goes on top. This lets you use heavier main line without overfilling the spool. Tie the backing to the spool with an arbor knot, wind it on loosely until the spool is three-quarters full, then tie your main line to the backing with a uni knot.
