Lead core fishing line is a specialized type of fishing line distinguished by its unique construction. This line has a lead core encased in a durable, braided fabric covering. Unlike monofilament or braided lines, the lead core imparts significant weight, facilitating the line’s sinking for deep-water fishing. Learning how to use lead core fishing line effectively can open up new avenues for anglers targeting species in deeper aquatic environments.

Grasping the intricacies of using lead-core fishing lines is crucial for several reasons. Primarily, the correct usage ensures that the line reaches the desired depth where the target species reside, enhancing the fishing experience. Additionally, proper handling and usage can prevent the common pitfalls associated with its weight and composition, such as tangling or undue wear on tackle.
The key advantage of using a lead core line lies in its ability to swiftly sink to significant depths without needing large sinkers or additional weight. This attribute makes it an indispensable tool for deep water trolling, allowing anglers to precisely target species dwelling far below the surface.
By mastering how to use lead core fishing line, fishermen can significantly improve their catch rates of deep-water species like trout, salmon, and walleye, making each fishing excursion more productive and fulfilling.
Understand the Basics of Lead Core Line
A. Composition and Structure of Lead Core Line
The lead core fishing line is characterized by its distinctive design, which incorporates a thin strand of lead at its core, enveloped by a durable, braided nylon outer layer. This composition is what gives the line its heft and enables it to sink quickly in water, reaching depths where typical lines might not.
The nylon sheath protects the lead core and ensures the line remains supple and manageable. Understanding the unique makeup of lead core line is the first step in leveraging its benefits for deep-water fishing.
B. Understanding Pound Test and Length Markers
The strength of a fishing line is denoted by its pound test, indicating the maximum weight the line can support without breaking. Lead core lines come in various pound tests, allowing anglers to choose based on their target size and fish species. Additionally, lead core lines with a color change are marked at regular intervals, usually every 10 yards.

These markers assist anglers in determining how much line they have out, which is critical for controlling the depth of the lure in the water. Knowing how to read these markers is essential for effective deep-water fishing.
C. Advantages and Limitations of Lead Core Line
Lead core lines offer significant advantages, particularly for deep-water trolling. Their innate heaviness allows for direct and efficient lure presentation at desired depths without additional weights. This direct contact with the lure offers better sensitivity to bites and a more immediate hook setting.
However, their rigidity and diameter compared to monofilament or braided lines can be limiting in some fishing conditions. They also require specific knots for tying to leaders and lures and can suffer from memory issues if not properly cared for. Balancing these advantages and limitations is key to making the most out of lead-core fishing lines.
Selecting the Right Reel and Rod
A. Choosing a Reel Suitable for Lead Core Line
When selecting a lead core fishing line reel, the primary consideration should be its capacity to accommodate the thicker, denser lead core line. A larger, robust reel with a deep spool is ideal to ensure there is sufficient space for the line, given its increased diameter compared to standard lines.
Additionally, a reel with a smooth, reliable drag system is essential. The drag must perform flawlessly, as the heavy lead core line exerts more pressure on the tackle, making smooth drag operation critical to compensate for the line’s lack of stretch and absorb the shock of a striking fish.
B. Selecting a Rod with Proper Action and Power
The rod chosen for use with lead core line must have the right combination of action and power to handle the unique characteristics of this fishing line. A medium-heavy to heavy rod with moderate to slow action is ideal.

This rod’s strength and flexibility allow for effective energy transfer when setting the hook and provide the necessary backbone to fight large fish. The moderate to slow action helps cushion the stress on the rig during a fight, minimizing the risk of breaking the line or losing the fish due to the lead core’s minimal stretch.
C. Matching Reel and Rod to Fishing Conditions and Target Species
Selecting the appropriate reel and rod setup for fishing with lead core line requires consideration of the specific fishing conditions and target species. A heavy-duty reel and rod combo is necessary for deep-water trolling in pursuit of large species such as lake trout or salmon. In contrast, targeting smaller species or fishing in shallower waters might allow for a setup with slightly less power.
The key is to ensure that the reel and rod selected can comfortably manage the weight and behavior of the lead core line while providing enough strength and sensitivity to effectively capture the target species under the prevailing conditions.
How to Use Lead Core Fishing Line: Spooling the Reel with Lead Core Line
A. Preparing the Reel and Line Spool
Before spooling, it’s crucial to set up both the reel and the new spool of the lead core line correctly. Ensure the reel is clean and functioning properly; any dirt or malfunction could affect the spooling process and, ultimately, the fishing experience. Similarly, inspect the lead core line for any defects or damages. Getting familiar with the line, especially noting the color pattern for depth control, is also advisable before beginning the spooling process.
B. Attaching the Lead Core Line to the Reel Arbor
Attaching the lead core line to the reel arbor securely is fundamental to prevent slipping under tension. Start by threading the line through the rod’s guides to the reel. If your reel has a spooling port, you can thread it directly without removing it.

Tie the line to the arbor using an arbor knot, which is suitable for a lead core line because of its simplicity and strength. Pull tight to ensure the knot fully cinches onto the arbor without slipping.
C. Properly Spooling the Line onto the Reel
The spooling process can begin once the line is securely attached to the reel arbor. Maintaining even tension on the line is essential as it transfers from the spool to the reel. This can be achieved by having someone hold the spool with a dowel or pencil, allowing it to spin freely, and applying light pressure.
Ensure the line lays evenly across the width of the reel; use your fingers (carefully to avoid injury) to guide the line if necessary. Fill the spool until there’s approximately 1/8th inch of space from the spool’s rim to prevent spillover. Properly spooling your reel ensures the line deploys smoothly, without twists or kinks, facilitating a better fishing experience.
Understanding Depth and Trolling Speed
A. Calculating Depth with Lead Core Line
In a controlled scenario, calculating the depth attained by a lead core line involves understanding its sinking rate, typically at 5 feet per color (every 10 yards). However, this rate can vary based on factors like the lure’s drag, current speed, and the trolling speed itself.
To estimate depth, anglers should consider the amount of line out (counted in colors), the trolling speed, and the lure type. It’s a generally accepted practice that slowing the boat’s speed can allow for deeper lure placement, as the line has less drag and can sink further.
B. Adjusting Trolling Speed for Desired Depth
Trolling speed is crucial for managing the depth your lure reaches. Generally, a slower speed allows the lead core line to sink deeper, while increasing speed raises the lure toward the surface. Experimentation is essential, as lures behave differently at various speeds and depths.

The challenge lies in finding the optimal speed that maintains lure action while achieving the desired depth, a balance that often requires fine-tuning based on real-time conditions and observations.
C. Monitoring Depth and Speed During Trolling
Consistently monitoring both depth and speed during trolling is vital for successful fishing with a lead core line. Modern fish finders and GPS speedometers can provide accurate readings, helping anglers make informed decisions on the fly. It’s important to note changes in depth due to bottom contour variations and to adjust the amount of line out accordingly.
Keeping a constant speed that optimizes the lure’s action while ensuring it runs at the right depth can significantly increase the chances of a catch. Adjustments should be made based on continuous observations and interpretations of the fish finder’s feedback, water conditions, and the response from the fish.
Tying Leaders and Lures
A. Selecting the Right Leader Material
When fishing with lead core lines, the choice of leader material plays a crucial role in the effectiveness of your presentation. Fluorocarbon is popular due to its near invisibility in water and abrasion resistance, making it ideal for cautious fish and rough conditions.

Monofilament leaders, on the other hand, provide more stretch, which can be beneficial in preventing break-offs during fierce strikes. The decision should be based on the target species, water clarity, and personal preference to ensure the best results.
B. Tying Leaders to Lead Core Line with Suitable Knots
Connecting a leader to a lead core line requires a knot that can maintain the integrity of both lines without causing unnecessary bulk. The Willis Knot is widely recommended for this purpose as it allows the leader to connect directly to the lead core without slippage, maintaining a smooth transition that enhances lure action.
It’s essential to carefully remove the lead from the core line’s end before tying the knot to ensure a tight and secure connection. A properly tied knot minimizes the risk of losing fish due to tackle failure.
C. Attaching Lures to Leaders for Effective Presentation
The final step in preparing your fishing setup is attaching lures to the leaders. This selection heavily depends on the target species and the conditions under which you’re fishing. Use a loop knot to attach lures to maintain maximum mobility, allowing for a more natural and enticing action in the water.
Whether you’re aiming for a slow, enticing wiggle or a fast, erratic dart, the right combination of lure and knot can make all the difference in attracting fish. Constant experimentation and adaptation to the fishing environment are key to mastering this aspect of fishing with lead core lines.
Fishing Techniques with Lead Core Line
A. Trolling for Trout, Salmon, and Walleye
Trolling with lead core lines is particularly effective for targeting trout, salmon, and walleye, enabling lures to reach the deeper waters where these species often reside. The key to successful trolling is matching the speed and depth to the fish’s preferred habitat.

For trout and salmon, early morning or late evening hours when they are more active near the surface can be ideal. Walleye, often found closer to lake bottoms, can be targeted throughout the day by adjusting the trolling depth accordingly. Lure choice should complement the depth strategy, with smaller spoons or minnow-like plugs being effective for trout and salmon and larger, more vibrant lures for capturing walleye’s attention.
B. Working Deep Water Structures and Drop-offs
Lead core lines excel in navigating lures around deep water structures and drop-offs, areas where fish tend to congregate. The weighted line allows anglers to keep their lures in close proximity to these structures, increasing the chance of a bite.
It’s essential to maintain a depth that keeps the lure just above the structure to avoid snagging while still appealing to the fish. This requires precise control over the amount of line out and may necessitate frequent adjustments as the boat moves over varying terrain.
C. Adjusting Depth and Presentation Based on Fish Activity
Observing fish activity and making immediate adjustments to both depth and presentation is crucial when fishing with lead core lines. Fish finders are invaluable tools for identifying where fish are actively feeding or holding. If fish are spotted at a specific depth, adjusting the amount of line out can position your lure within their vicinity.
Similarly, changing trolling speed can alter the lure’s action, potentially making it more appealing to the target species. Seasonal changes, water temperature, and time of day influence fish behavior, requiring continuous adaptation of fishing techniques for optimal results.
Playing and Landing Fish
A. Maintaining Proper Tension on the Line During Hookup
When you’ve successfully hooked a fish while using a lead core line, it’s essential to maintain the right amount of tension on the line. Too much tension can lead to a break-off, while too little can result in the fish throwing the hook.

The key is to keep a steady, controlled pressure that ensures the hook stays firmly in place without overstressing the line or the fish. Adjusting the drag on your reel accordingly can help manage this balance, providing enough resistance to tire out the fish while preventing any sudden, forceful tugs that could compromise the setup.
B. Fighting Fish While Minimizing Stress on the Line
Fighting a fish on a lead core line requires a nuanced approach to minimize stress on both the line and the fish. Due to their inherent stiffness and weight, lead core lines are less forgiving than monofilament or braided lines.
Anglers should employ a combination of reel management and rod positioning to absorb the fish’s runs and jump. The goal is to guide the fish towards you in a steady, controlled manner. Utilizing the rod’s flex to buffer against sudden movements and keeping the line at a constant angle can help reduce the risk of line breakage.
C. Landing Fish Safely and Effectively
Landing a fish safely and effectively is the culmination of a successful catch. For anglers using lead core lines, a net is often the best choice for securing the fish once it’s close to the boat. It’s crucial to wait until the fish is sufficiently tired and near the surface to avoid premature netting attempts that could spook or stress the fish further.
Coordination between the angler and the person netting the fish is vital; the angler should lead the fish headfirst into the net with careful rod management, while the netter should be ready to lift the fish out of the water smoothly and swiftly. This final step requires patience, timing, and communication to ensure the fish’s health and the catch’s safety.
Care and Maintenance of Lead Core Line
Regular care and maintenance are essential for ensuring the durability and performance of your lead core line. Proper handling can significantly extend the lifespan of your line, making your fishing trips more productive and enjoyable.

Early detection of these issues can prevent line failure during future fishing activities.
B. Cleaning Line Regularly to Remove Debris and Abrasives
Lead core lines can accumulate debris, salts, and microscopic abrasives that wear down the line over time. To clean your line, gently rinse it with fresh water after each use, especially if you’ve been fishing in saltwater. For a deeper clean, use a mild soap solution and a soft cloth to carefully wipe down the line, removing any accumulated materials that could cause wear. Allow the line to dry completely before winding it back onto the reel to prevent mold and mildew growth.
C. Storing Line Properly to Extend Lifespan
Proper storage is critical to maintaining the condition of your lead core line. Avoid exposing the line to direct sunlight for extended periods, as UV rays can weaken the material. Keep the line in a cool, dry place when not used.
Also, ensure that the line is neatly coiled or wound onto the reel without any kinks or twists that could cause internal stress. You can greatly extend its functional lifespan and reliability by taking deliberate steps to store your lead core line correctly.
