The Okuma Obsidian is Okuma's lightweight take on a big pit carp reel, and it sits well above the Okuma 8K in both price and spec. It's a 12000-size reel with a 35mm spool stroke, super-slow oscillation and a worm shaft transmission, and Okuma have made the frame, sideplates and rotor from their C-40X carbon to keep the weight down to 520g.
It comes with a spare spool and two line reducers in the box, so you can set one spool up with a different line and swap between them on the bank. For carp anglers who want big pit casting without the weight of a heavier reel, I think it's one of the more interesting options at this sort of money, and it's a genuine alternative to the Shimano and Daiwa reels around it.
Okuma's C-40X carbon is the main story with the Obsidian. It's used for the frame, the sideplates and the rotor, and it's what keeps a 12000-size reel down at 520g, which is light for a big pit.
Okuma say the material is corrosion resistant too, and that's worth having on a reel that spends its life out on the pod in all weathers.
The moving parts have been kept light as well. There's an A7075 aluminium main shaft, an ultra-light spool and a screw-in aluminium handle, which I'd always take over a folding handle on a big pit because there's less to work loose.
The bail is a one-piece design, and the tangle-guard rotor is there to stop line catching behind the spool.
It's a smart, all-black reel with the Obsidian name picked out on the spool, and to be fair it looks the part sitting next to reels from the bigger names.
Line lay is where the Obsidian should earn its place. The 35mm spool stroke, super-slow oscillation and worm shaft transmission all work together to lay the line evenly across a long spool, and that's what lets it peel off cleanly when you're casting at range.
The DLC Even Flow Roller is a good detail too. It's a line roller with a Diamond-Like Carbon coating, and that coating is there to cut friction and wear at the point where the line runs under load, which matters when you're winding leads and fish back from distance all session.
The retrieve is 103cm of line per turn of the handle, which is right in line with the big pits around it, so you aren't giving anything away when you're winding in to recast.
Add in the frictionless main shaft design, which is there to take resistance out of the wind, and I think it has everything I'd want from a distance reel.
The Obsidian uses Okuma's Carbonite drag system, which is rated to a maximum of 12kg. That's far more than you'll need for UK carp, and Okuma pitch it as a drag that stays smooth and consistent under pressure, which is what counts when a big fish takes line close to the net.
It's set from the knob on the front of the spool, like most big pits, so there's no baitrunner lever.
You fish it with the drag slackened off so a take can pull line, then tighten it once you're in, and anglers coming from free spool reels might take a session or two to get used to that.
If a quick drag is high on your list, the Daiwa Emblem's QDM drag and the Shimano Ultegra 5500 XTD's Instant Drag are both sold on exactly that, so they're worth a look alongside it.
That's why I've scored the Obsidian's drag a touch below its casting, although the 12kg ceiling still gives you plenty in reserve near snags.
The Obsidian sits near the top of Okuma's carp range, a long way above the Okuma 8K, and for the extra you're getting the C-40X carbon body and rotor, an aluminium shaft and handle, the DLC roller and a spare spool with two reducers.
Against the big names it's priced between the Shimano Ultegra 5500 XTD and the Daiwa Emblem 35 SCW, and it holds its own on paper.
It weighs 520g, only 20g more than the Ultegra, and the spare spool and reducers mean you can carry two different line setups without buying a second reel.
It suits carp anglers who fish big pits and larger waters, want a light reel that won't wear them out over a long session, and like the idea of a spare spool loaded with a different line ready to swap in.
| Feature | What this means |
|---|---|
| C-40X Carbon Frame, Sideplates and Rotor | Okuma's C-40X is a high-grade graphite carbon material used throughout the body, sideplates, and rotor. It keeps the reel extremely light without sacrificing rigidity, and it resists corrosion well so it holds up in wet and muddy bankside conditions. |
| Cyclonic Flow Rotor | The rotor is designed with vents that allow air and water to flow through rather than sit inside the reel. This helps dry the internals faster and reduces the chance of corrosion building up over time, which is useful if you fish in the rain or near the water's edge. |
| Ultralight Spool and A7075 Aluminium Shaft | The spool is kept as light as possible, and the shaft it sits on is machined from A7075 aluminium, which is a particularly strong and lightweight alloy. Together they reduce the overall weight of the reel significantly, cutting down fatigue on long sessions where the rods are in your hands a lot. |
| Frictionless Main Shaft Design | The main shaft is engineered to eliminate resistance as the spool moves during retrieve. This means reeling in feels noticeably smoother and lighter, which matters when you're playing a fish or winding in at range repeatedly throughout a session. |
| Super-Slow Oscillation and 35mm Stroke | Oscillation refers to how the spool moves up and down as line is retrieved. A super-slow oscillation rate combined with a 35mm stroke lays the line in tight, even, overlapping layers. This improves casting distance and accuracy because the line leaves the spool cleanly without coiling or bunching. |
| Worm Shaft Transmission System | A worm shaft drives the spool movement rather than a conventional cam system. This produces a more consistent and precise oscillation, which ties in with the superior line lay and contributes to the smooth, wobble-free feel when winding. |
| One-Piece Bail | The bail arm is formed from a single continuous piece of wire rather than being jointed. This removes a weak point that can flex or fail under pressure, making the bail more reliable and longer lasting. |
| DLC Even Flow Roller System | The line roller has a Diamond-Like Carbon (DLC) coating, which is an extremely hard surface finish that resists grooving from the line passing over it. It also helps guide the line evenly onto the spool, reducing the risk of tangles and prolonging the life of your mainline. |
| Carbonite Drag System with Fast Progressive Drag | Okuma's Carbonite drag uses carbon fibre washers to deliver smooth, consistent resistance when a fish takes line. The fast progressive setting means a small turn of the drag knob produces a noticeable increase in pressure, giving you quick, precise control when a fish makes a sudden run. |
| 9HPB + RB Bearing Setup | The reel is fitted with 9 high-performance bearings plus a roller bearing. More quality bearings generally means a smoother, more stable retrieve and less play or wobble in the mechanism, which you'll notice most when winding in quickly or under load from a fish. |
| Tangle Guard Rotor with Rotor Brake | The rotor is shaped to stop line from slipping behind it and wrapping around the shaft, which is a common source of frustrating tangles. The rotor brake prevents the rotor from spinning freely when the bail is open, keeping everything tidy when you're casting or setting up. |
| Ultralight Screw-In Handle | The handle screws directly into the body rather than using a folding or clip-in mechanism, which keeps it secure and wobble-free in use. It is also built with weight-saving in mind, contributing to the overall lightweight feel of the reel during a long session. |
| Spare Spool and Two Reducers Included | The reel comes with an extra spool straight out of the box, so you can pre-load two different lines and swap between them quickly at the waterside. The two included reducers allow you to adjust the spool capacity, making it easier to use lighter or thinner lines without overfilling or underfilling the spool. |
