In the world of angling, mastering the technique of attaching the leader line to your main line is a fundamental skill that can significantly impact your fishing success. The leader line, often referred to as the "sensitive" or "tippet" line, is the crucial link between your main fishing line and your hook or lure. It is designed to be thinner and more flexible, allowing for greater sensitivity and the ability to present your bait more naturally to fish. Here, we delve into the ins and outs of how to properly attach your leader line, ensuring you're ready to cast out with confidence.
Understanding the Components

Before diving into the specifics of attaching your leader line, it's important to understand the components involved:
- Main Line: The main line is the primary fishing line that runs from your rod tip to your reel. It is typically thicker and more durable than the leader line.
- Leader Line: The leader line is attached to the main line and is responsible for the connection between the main line and the hook or lure. It is designed to be more sensitive and to break on a fish's sharp teeth without snapping the main line.
- Swivel: A swivel is a metal or plastic device that joins the main line to the leader line. It helps prevent line twist and allows for a smooth transition between the two lines.
Choosing the Right Leader Line
The choice of leader line depends on various factors, including the type of fish you're targeting, the conditions of the water, and the type of bait or lure you're using. Here are some general guidelines:
- Monofilament: The most common type of leader line, monofilament is flexible and has a natural appearance. It is suitable for a wide range of fishing scenarios.
- Fluorocarbon: This type of leader line is less visible in water and is excellent for fishing in clear or stained waters. It is also more abrasion-resistant than monofilament.
- Braid: While not commonly used as a leader line due to its lack of flexibility, braid can be used in certain situations, especially when targeting large fish or when fishing in heavy cover.
Attaching the Leader Line
Now that you've chosen the right leader line, it's time to attach it to your main line. Here are the steps to follow:
Cut Your Leader Line: Measure the desired length of your leader line and cut it to size. For most freshwater fishing, a leader length of 6 to 12 feet is sufficient.
Prepare the Main Line: Make sure your main line is clean and free of knots or snags. If you're using a new spool, it's a good idea to trim the tag end of the line to prevent it from unraveling.
Select a Knot: There are several knots that can be used to attach the leader line to the main line. The most common and reliable knots for this purpose are the Clinch Knot, the Palomar Knot, and the Uni Knot.
Clinch Knot: Start by creating a loop in the end of the leader line. Pass the tag end through the loop and pull it tight. Then, make a second loop about an inch from the end of the tag. Pass the tag end through this second loop and pull it tight. Finally, wet the knot and tighten it by pulling both the main line and the tag end.
Palomar Knot: This knot is particularly good for attaching a swivel to the leader line. Create a loop in the end of the leader line, pass the tag end through the loop, and make a second loop about an inch from the end of the tag. Pass the tag end through this second loop and pull it tight. Wet the knot and tighten it.
Uni Knot: This is a very strong knot that is also quite simple to tie. Pass the tag end through the loop created by the main line and leader line. Make a loop in the tag end and pass it through the loop you just created. Pull both ends tight and wet the knot.
Attach a Swivel (if necessary): If you're using a swivel, attach it to the end of the leader line using the Palomar Knot or another suitable knot. Make sure the swivel is tight and that there is no slack in the line.
Secure the Leader to the Main Line: Once the swivel is in place, you can tie the leader line to the main line using one of the knots mentioned above. Make sure the knot is tight and secure.
Check Your Knot: After tying the knot, give it a good pull to ensure it is secure. It's also a good idea to do a few practice casts to make sure the leader line is attached properly and there is no line twist.
Conclusion
Attaching your leader line correctly is a crucial step in the fishing process. By choosing the right leader line, using the appropriate knots, and ensuring a secure connection, you'll be well on your way to enjoying a successful fishing trip. Remember, practice makes perfect, so don't be afraid to experiment with different knots and leader lengths to find what works best for your fishing style and the species you're targeting. Happy fishing!
