Certate is very smooth, tough and light-weight spinning reel, with long life and high reliability. It has sturdy aluminum alloy body, over-sized extra duralumin master gear, the innovative Magnetic Seal system (Magseal) at the line roller and the main shaft, salt-resistant ball bearings and etc, to offer the most reliable spinning reel to all anglers on any kind of water.
The Magseal, the combination of magnetic oil and ring magnet, is very effective to protect mechanicals dry, without adding any dragging. With the Magseal, gear problems are significantly reduced, and gear life is improved by 150% than regular grease seal models. At the line rollers, bearing noise problems were eliminated by 90%. These two parts are the bottle neck of spinning reels, and Magseal is the real innovation for long life of spinning reels.
The super light weight Air Rotor make it cranks much lighter than other spinning reels. It reduces 25% of innertia from rotor. This is the most reliable arsenal spinning reel among 1000-4000 sized spinning reels in market.

3012H: best matching to 8-10ft surf wading, and freshwater large game fishing with 10-30g(3/8-1oz) rigs, with faster application. Jun's comment: I've used '04 Certate 2500R for 6 years, and been using '10 Certate 3012H for light inshore fishing. I love them. For both reels, all moving parts feel very sturdy after a few years of use. Certarte is a very solid durable reel. Drag is very smooth and tough. It is quite a bit expensive reel, but it is worth the investment. With the added Magseal at line roller, 13Certate is the must buy.
