Product Details and Uses

Okuma Obsidian OSD12000-35AY: The Ultralight Big Pit Revolution

At Gerry’s Fishing, the Okuma Obsidian OSD12000-35AY represents the pinnacle of modern reel technology for the serious specimen angler. By utilizing C-40X Carbon—a long-strand carbon fiber material that is significantly lighter and stronger than standard graphite—Okuma has created a massive big-pit reel that weighs an incredible 520g. This reduction in weight is critical for maintaining rod speed during high-velocity casts and reducing physical fatigue during long sessions.

The Obsidian is designed for “Big Water” dominance, featuring a 35mm long-stroke spool and a Super Slow Oscillation system. This combination creates a near-perfect line lay, allowing the line to leave the spool with almost zero friction. With 18kg of carbon fiber drag and a frictionless main shaft design, this reel is as smooth as it is powerful, ensuring you have the upper hand even against the most explosive European carp.

Elite Technology & Performance Features

C-40X Carbon Frame & Rotor: This advanced material provides a rigid, twist-free housing for the gears while shedding significant weight. It is also naturally resistant to corrosion, making it a long-term investment.
Super Slow Oscillation: By moving the spool up and down at a very slow rate, the reel wraps the line in precise, parallel layers. This is the secret to hitting maximum distance, as it eliminates “line bite” and friction.
Frictionless Main Shaft: A specialized internal design that prevents the main shaft from coming into contact with the gears, resulting in an incredibly light and effortless handle turn, even under the weight of a heavy lead.
DLC Coated Even Flow Roller: The line roller is treated with a Diamond-Like Carbon (DLC) coating. This ultra-hard, smooth surface drastically reduces line wear and prevents line twist, especially when using thin-diameter braids.
One-Piece Bail Arm: Unlike standard bails with a joint at the roller, the Obsidian features a seamless one-piece construction. This ensures the line flows perfectly into the roller every time without snagging.
Rotor Brake & Tangle Guard: The rotor locks automatically when the bail is open to prevent accidental closures during a cast. Additionally, a built-in guard prevents the line from slipping behind the spool and tangling around the main shaft.
Fast Progressive Drag: Switch from “free-running” to “battle mode” in less than half a turn, providing instant precision when a fish runs near snags.

What’s in the Box?

One of the best values offered by the Obsidian is the inclusion of professional-grade accessories:

Spare Aluminum Spool: A full-size secondary spool for different line diameters.
Two Line Reducers: These allow you to reduce the massive 12000 capacity down to an 8000 or 1500 size. This is perfect if you want to use expensive braided lines without needing hundreds of meters of backing.

Gerry’s Pro Tip: The A7075 Aluminum Shaft is the same material used in aerospace engineering. It is incredibly stiff but ultra-light. When paired with a premium 13ft distance rod, the reduced weight of the Obsidian allows you to reach tip speeds that will add 10–20 yards to your previous personal best casting distance
