The usage method of fly pin is as follows:
Preparation tools: Need to prepare throwing aids, eight character rings, main lines, fly hooks, and space beans. The throwing aid is used to increase the throwing distance and stability, the eight character ring connects the pin with the main line to prevent entanglement, the main line transmits force, the fly hook is a bait, and the space bean is used to fix the position.
Install the assistive device and the eight shaped ring: Remove the pin from the assistive device, hang the tied eight shaped ring on the pin, then put the pin back into the pin hole of the assistive device and push it up to ensure a secure connection.
Connect the main line: Thread the main line through the pinhole, loop it one or two times, use the middle finger to lift the loop, and turn the short line around the long line for 3-8 turns (the specific number of turns can be adjusted according to the actual situation), then pull the short line head out of the loop, close the line and cut off the reserved short line head.
Fixed Space Bean: Push the space bean to the top of the fly hook's head to prevent entanglement of the string, and adjust the position of the fly hook as needed.
Hang the fly hook: Hang the fly hook onto the other end of the pin, ensuring that the hook tip is facing upwards for easy fish hooking.

Usage tips and precautions:
Selection of investment aid: Choose according to the fish layer and water quality. Use a gold glitter dispenser for clear water surface, and a silver dispenser for turbid water surface; Use a float assist to catch upper level fish, and a slow sinking assist to catch lower level fish.
Collection speed: Adjust according to the fish situation. Slow down at any time with a fish heel, and speed up at any time without a fish heel, but operate in shallow water with visible underwater fish.
Hook number selection: Select based on the size of the target fish. Generally, the larger the hook size, the smaller the hook size. Common sizes include 12, 14, 16, 18, 20, and 22 (which are difficult to purchase).
Operation practice: At the beginning of use, multiple attempts may be necessary to avoid disturbing the fish due to improper operation. Practice more to master the skills proficiently and improve the success rate of catching fish.
