Who it suits
Is it right for you?
Great for
- Carp anglers fishing at mixed ranges. The two spool depths let you tailor the setup for 12lb or 15lb mono without filling the reel with loads of unwanted backing.
- Anglers who like a compact, balanced rod-and-reel setup. The lighter body and dark wood-paddle quick-fold handle keep the outfit feeling neat and manageable on the bank.
Maybe skip if
- Anglers who want the biggest possible big-pit silhouette. The Compact is designed to be more manageable, so it won’t have the same oversized feel as a full-size distance reel.
- Fishermen who need an ultra-fast retrieve. The 4.8:1 gearing and approximately 0.95m retrieve are smooth and controlled rather than rapid-fire.

- The Compact version is 200g lighter than the original ESP Onyx reel.
- Two bespoke machined anodised aluminium spools are supplied.

Quick verdict
Verdict
The ESP Onyx Compact Big Pit Reel looks a proper tidy option for carp anglers who want long-range capability without lugging oversized reels around. The two shallow spools, smooth line lay and clever drag adjusters give it plenty of practical appeal.
It’s not the cheapest-looking bit of kit, and the compact body won’t suit everyone chasing maximum big-pit heft. But for most carp work, it’s a bob-on balance of capacity, control and ease of use.

Machined aluminium spools, stainless-steel bearings, a stainless line clip and a smart finish give it a properly solid tackle-box feel.
Slow oscillation, controlled gearing and a near-metre retrieve rate suit accurate carp fishing and long-range winding.
The line capacity, tidy lay and two drag options help you fish confidently across open water, margins and snag-free distance spots.
No backing is needed on the shallow spools, the handle folds quickly and the drag choices are easy to understand.
Two useful spools and interchangeable adjusters add genuine versatility, although compact specialist reels can be a sizeable spend.

The full rundown
Everything you'll want to know about the ESP Onyx Compact Big Pit Reel
There’s a lot to like about a compact big pit reel. You still want the line capacity and control for proper carp work, but you don’t always want a massive brick hanging off the bottom of your rod. That’s the thinking behind the ESP Onyx Compact Big Pit Reel. It keeps the serious spool options, but trims 200g from the original Onyx design. Handy when you’re lugging a full load of kit to the lake, mate.
The reel comes with two bespoke machined anodised aluminium spools, and this is where it gets properly useful. The shallow spool takes 300m of 15lb line, while the ultra-shallow version takes 300m of 12lb line. That covers a big chunk of everyday carp fishing, from closer island work to swims where you need a decent bit of line in reserve.
There’s no need for backing line with the shallow spools, either. That makes filling them a lot less of a faff, especially if you’re setting up three rods together. A 1,000m bulk spool of mono will fill three reels, which is a nice little bit of practical thinking. Less leftover line, less messing about, and a tidy fill ready for the next bite-time.
Line lay is handled by slow oscillation, helping the line sit smoothly across the spool. That matters when you’re punching a cast towards the far margin or dropping a rig on a clipped-up spot. A tidy line lay can help the line leave the spool cleanly, while also making the reel easier to fill properly in the first place. It’s the sort of detail you might overlook until a spool starts looking a bit ropey.
Drag control is another strong point. Two interchangeable adjusters are supplied: the FD Fine Drag and the RL Rapid Lockdown. The Fine Drag option gives you more measured control when you’re playing a fish and want to make small adjustments. The Rapid Lockdown version goes from free-running to locked down in about half a turn, which is dead handy when a carp kites into a snaggy margin.
That means you can set the reel around the venue and your own fishing style. For open-water work, a freer drag can give you a bit more cushioning during those first thumping runs. Near weed, reeds or an ugly snag, rapid lockdown gives you the option to get serious quickly. You still need sensible rod angles and a bit of common sense, of course. No drag knob turns a bad swim into a safe one.
The Compact has 7+1 stainless-steel bearings, a 4.8:1 gear ratio and a retrieve rate of roughly 0.95m per handle turn. In plain English, it’s built around smooth, controlled winding rather than frantic speed. That suits most carp situations nicely, especially when you’re winding in from distance or bringing a rig back through weed without wanting the reel to feel rushed.
The handle folds quickly and finishes with a dark wood paddle, giving the reel a smart classic touch without making it look fussy. There’s also a stainless-steel line clip designed to avoid damaging your mono, which is important if you fish clipped up regularly. Add in the 550g listed weight and the compact proportions, and this looks like a cracking all-rounder for anglers who want capacity and control without an overgrown reel on the rod.

Our take
The compact reel that keeps things serious
The big draw here is flexibility without loads of faff. You get a shallow spool for 15lb line and an ultra-shallow spool for 12lb, both holding 300m. That’s proper useful for anglers who fish different waters or like changing line setups with the seasons.
The compact body is also 200g lighter than the original ESP Onyx, with the listed reel weight sitting at 550g. That difference soon adds up when you’re carrying three rods, alarms, bobbins and enough bait to feed half the lake.
Closer look
A tidy package with proper carp features
The big attraction is the pair of spool options. The shallow spool is set up for 300m of 15lb line, while the ultra-shallow spool holds 300m of 12lb. That gives you a clean choice for different venues and tactics, without needing to pile on backing line first. Three reels can be filled from a 1,000m bulk spool, too, which is a proper sensible touch if you’re lining up a three-rod setup.
Slow oscillation helps produce a smooth line lay, while the 7+1 stainless-steel bearings and 4.8:1 gearing are aimed at controlled, dependable operation. The quick-fold handle has a dark wood paddle, and the stainless-steel line clip is designed to be kinder to your line when you’re clipped up and fishing accurately.
Worth knowing. You get both the FD Fine Drag and RL Rapid Lockdown adjusters, but they’re interchangeable rather than used together. Fine Drag is the one for gradual changes; Rapid Lockdown is the cheeky half-turn option when you need to go from free-running to locked down quickly.
Who it suits
Built for flexible carp fishing
This reel makes most sense for carp anglers who fish a mixture of ranges and waters. The 12lb ultra-shallow setup will suit lighter work where the swim allows it, while the 15lb shallow spool gives you a bit more confidence when the venue, weed or fish call for stronger mono. The 300m capacity on both is more than enough for plenty of normal carp situations.
It should also appeal if you’re trying to keep your gear compact. At a listed 550g, and 200g lighter than the original Onyx, it won’t feel quite as bulky on the rod. That can make a difference on long walks, roving sessions and any trip where your barrow is already groaning under the weight of everything else.
If you mainly fish tight snaggy edges, you’ll probably favour the Rapid Lockdown adjuster and a sensible heavy setup. If you’re fishing open water and want more finesse while playing a lump, the Fine Drag option gives you greater adjustment. Either way, the reel is aimed at practical carp anglers rather than flashy gadget collectors.
FAQs in full
The bits you’ll want cleared up
The Compact isn’t simply a small reel with a short spool. It’s designed to retain useful big-pit capacity while being 200g lighter than the original Onyx. That makes it a good middle ground: more serious than a standard compact carp reel, but less cumbersome than some full-size distance models.
The spool choice is straightforward. The shallow spool takes 300m of 15lb mono at around 0.37mm diameter. The ultra-shallow spool takes 300m of 12lb mono at around 0.33mm. Match the spool to the line you want to fish, fill it neatly, and you’re away. No backing-line faff on the shallow spools.
Worth knowing. The approximately 0.95m retrieve rate is worth keeping in mind. It’s plenty for normal carp work and feels controlled, but anglers who like to wind in at top speed may prefer a faster-retrieve reel. For most rods-on-the-spot fishing, though, the steady gearing is a sound trade-off.

Which spool should I use?
Use the shallow spool for 15lb line and the ultra-shallow spool for 12lb line. Both hold 300m, so pick according to the line strength and water you’re fishing rather than chasing extra capacity you don’t need.
