Daiwa Certate-HA Spinning Reels feature Daiwa's Mag Sealed technology. Magnetic oil, controlled by a magnetic field, forms a seal to prevent water intrusion between the reel's rotor and body, preventing its intrusion into the rotor bearing and gear box. The result is a water-tight seal with much lower friction than rubber type seals. You'll notice the light, smooth-turning feel immediately.

Certate-HA also employs Daiwa's Air Rotor and Hollow Air Bail. The Air Rotor design uses corrosion-proof ''Zaion'' carbon construction, which helps reduce weight while offering maximum strength.
