The rear drag spinning reels has become the preferred equipment for many sea fishing enthusiasts due to its convenient operation and flexibility. Correctly assembling the fishing line is not only a key step to improve fishing efficiency, but also the basis for ensuring fishing success.

Choose the right fishing line
Before assembling the fishing line, it is crucial to choose the right fishing line. The type and specification of the fishing line directly affect the fishing effect.
Fishing line type: Common types of fishing lines on the market include monofilament line, braided line and fluorocarbon line. Monofilament line is suitable for freshwater fishing, while braided line is particularly suitable for sea fishing due to its high strength and small line diameter. Fluorocarbon line is suitable for specific fishing scenes due to its concealment in the water. When choosing, the appropriate type of fishing line should be determined according to the size of the target fish species and the characteristics of the fishing environment.
Line diameter and strength: When choosing a fishing line, the line diameter and tensile strength should be determined according to the size of the target fish species. Generally speaking, the smaller the line diameter, the smaller the water resistance, but its strength is relatively low. Therefore, it is necessary to balance the line diameter and strength when choosing to ensure that it can effectively deal with the expected fish.

Steps to assemble the fishing line
Assembling the fishing line is a meticulous process, and the following are the specific steps:
Preparation: Before starting to assemble, make sure all tools and materials are ready, including reels, fishing lines, scissors, fishing line clamps and hooks.
Inspect the reel: Before assembling the fishing line, first conduct a thorough inspection of the drag reel. Make sure there is no salt, sand or other impurities inside and outside the reel. Check various components such as the brake system, bearings and handles to ensure that they are in good working condition.
Fitting the line:
1. Secure the fishing line: Pass one end of the fishing line through the coil of the reel to ensure that the fishing line is firmly fixed to the main shaft of the reel. You can use a fishing line clamp or tie a knot to secure it to ensure that it will not come loose during use.
2. Coil direction: Confirm that the coil direction of the fishing line is consistent with the rotation direction of the reel. You can verify this by manually rotating the reel to avoid tangling after loading.
3. Loading tension: Maintain proper tension during the loading process. You can hold the fishing line by hand to ensure that it is not too loose when winding it into the reel. A too loose coil is easy to tangle when fishing, affecting the use effect.
4. Even loading: Make sure the fishing line is evenly distributed on the main shaft of the reel. You can guide the fishing line manually to ensure that it does not overlap or stack when loading.
5. Line length: Adjust the length of the fishing line according to the fishing environment and the characteristics of the target fish species. Generally, you need to leave enough margin to cope with deep-sea fishing and strong escapes of fish.

Fixing and cutting: After the line is loaded, it needs to be fixed and cut. Use fishing line clips or knots to fix the fishing line to ensure that it will not come loose during use. Then, use scissors to cut off the excess fishing line and ensure that the end of the fishing line is neat. Be careful not to cut it too short to avoid affecting subsequent fishing operations.

Adjustment and testing: After assembly, adjustment and testing are crucial steps. Adjust the drag force of the reel according to the size of the target fish species. The drag force can be tested by pulling the fishing line to ensure that it is suitable for the target fish species. At the same time, the flexibility of the fishing line is tested in water to ensure its performance in actual use.
