Although the shallow spool design reduces entanglement, how to ensure that the fishing line will not jump out of the spool or become tangled due to centrifugal force when the line is quickly reeled in and released?

The subtle balance of shallow spools
The core of shallow spool design is that it fundamentally reduces the risk of entanglement by reducing the overlap of the fishing line during the winding process. This design concept seems simple, but it actually contains profound physics principles and a deep understanding of the needs of anglers. When the line is quickly reeled in and out, the fishing line often needs to withstand large centrifugal forces, especially when the reel is spinning at high speed. This force is enough to make the fishing line in traditional deep spools become tangled or even jump out of the spool.

However, the shallow spool of FD reels effectively limits the scope of centrifugal force by shortening the winding path of the fishing line. The fishing line is closer to the axis on the shallow spool, which means that at the same rotation speed, the fishing line on the shallow spool is subject to much less centrifugal force on the fishing line, which reduces the risk of the fishing line being out of control due to excessive centrifugal force.

Ingenuity in engineering details
To achieve this balance, the design team of the ultra-small feed reel FD worked hard on many aspects. First, they carefully selected the material and surface treatment of the spool. The surface of the spool may have a slightly convex or concave texture design. These subtle concave and convex structures not only increase the friction between the fishing line and the spool, preventing the fishing line from sliding or jumping out when rotating at high speed, but also help guide the fishing line to be arranged in an orderly manner during the reeling process to reduce confusion.

The diameter and depth ratio of the spool has also been strictly calculated and optimized. Although a large diameter can provide more storage space, it will also increase the risk of the fishing line losing control due to centrifugal force; while a small diameter may limit the amount of storage. Therefore, the FD reel has found a consummate balance point, which not only ensures sufficient storage capacity but also ensures the stability of the fishing line.

Intelligent design and user experience
In addition to the design optimization at the physical level, the FD reel also incorporates intelligent elements to enhance the user experience. For example, some high-end models may be equipped with an intelligent sensing system that can monitor the rotation speed of the spool and the tension changes of the fishing line in real time. When it is detected that the fishing line may lose control due to excessive centrifugal force, the system will automatically adjust the rotation speed of the reel or apply appropriate resistance to keep the fishing line stable. The FD reel also pays attention to every detail of the user experience. For example, its handle design conforms to ergonomic principles, and is comfortable and non-slip; the operation interface is simple and clear, allowing anglers to easily get started; at the same time, it also has waterproof and dustproof functions to ensure normal use in harsh environments.
