🚀 Why the Avail Microcast Spool 20MT?
✅ Ultra-light & sensitive:
- The reduced weight improves the starting inertia, making throws more precise and smoother.
✅ Two spool depths for individual setups:
-
2.4 mm – Perfect for finesse bass fishing & trout fishing with PE line (approx. 1.5 PE)
-
4.2 mm – Ideal for lighter fluorocarbon fishing with 8–12 lb FC and for lures/shads
- Use the original SVS Infinity centrifugal brake
🔧 Important Notes for Use:
❗ Thumb only on the wrapping surface!
- Direct thumb pressure on the spool edge can damage the anodizing.
❗ Do not wind the cord too tightly!
- Especially with nylon, excessive tension can lead to damage.
❗ Clean and oil the bearings before use!
- Factory-applied rust protection grease – for optimal performance, please degrease & re-lubricate.
