Avail Microcast Spool for Daiwa 21 Zillion – Maximum Performance for Precision Casting

If you want to get the most out of your Daiwa 21 Zillion SV TW 1000, there’s no way around the Avail Microcast Spool. This high-end spool made in Japan drastically reduces spool weight, resulting in faster, more precise, and effortless casting performance – even with light lures.

While the original spool weighs a solid 13 g, this spool weighs only 7.3 g (including bearing!). The lower rotational inertia means: faster rotation, less starting resistance, and immediate acceleration during the cast. The result? You effortlessly reach greater distances and can present your lures with pinpoint accuracy.

Why this spool is a gamechanger

✔ Ultra lightweight: Reduced weight for noticeably better spool response
✔ Precision casting: Ideal for light lures, delicate presentations, and finesse techniques
✔ Maximum control: Improved acceleration and smoother line release
✔ Super duralumin: Highest stability with minimal weight
✔ Optimized line capacity: Perfectly matched for PE 1.2 / 100 m

Unlike the standard spool, the Avail Microcast not only allows for more casting distance but also a more sensitive lure control, which is crucial when fishing with jigs, wobblers, or softbaits. Especially when targeting perch, zander, or sea trout, this spool provides the decisive advantage to deliver your lure exactly where the predators lie in wait.

Important usage notes

🔹 Start with maximum brake force: Set the magnetic brake to MAX on the first cast to get used to the new casting behavior.

🔹 Extremely lightweight design: To minimize weight, the spool was made as thin as possible without sacrificing stability. Due to the special construction with a larger hollow space, the internal running noise may increase – however, this has no impact on performance.

🔹 Handle the spool edge gently: If you use the spool edge to brake with your thumb, the anodizing can be damaged by friction. Instead, use the line winding surface to stop.

🔹 Wind the line with the correct tension: Too much tension when spooling can damage the spool. Especially with stretchable lines like nylon, the winding should be not too tight.

🔹 Maintenance before first use: The bearings are factory-treated with anti-rust grease. If the spool turns stiffly, degrease, clean, and lubricate the bearings with high-quality reel oil.

🔹 Bearing replacement: Pay attention to the exact bearing size. When replacing bearings, be careful with the shaft, drive pin & co. to avoid damage – replacement is at your own risk.

Conclusion: The Avail Microcast Spool – The ultimate upgrade for your Daiwa 21 Zillion

With this tuning spool, you turn your reel into a true precision tool. Less weight, faster response, better control – perfect for anyone who won’t compromise on lure control and casting distance.

🔹 Noticeable improvement in casting distance and precision
🔹 Optimal for light lures and delicate techniques
🔹 Japanese high-end technology for maximum performance

Anyone who really wants to push their 21 Zillion SV TW 1000 to the limit can’t go without this spool. 🚀
