Who it suits
Is it right for you?
Great for
- Carp anglers fishing larger lakes and reservoirs. The longcast spool and generous capacity give you useful insurance when the far-bank spot is properly out there.
- Anglers who like baitrunner control. You can leave a rod fishing with a controlled free-spool setting, then switch onto the main drag when a screaming take arrives.
Maybe skip if
- Commercial fishery anglers fishing close in. The extra size and capacity could be a bit daft when most bites are coming from the margins.
- Anyone building an ultra-light carp setup. The Big especially has real presence, so it won’t pair as neatly with lighter, shorter rods.

- Available in Medium and Big sizes.

Quick verdict
Verdict
The Shimano Baitrunner XT-B Longcast is a serious carp reel for distance work, with a smooth baitrunner system, useful line capacity and enough drag power for proper lumps. The Medium is the more balanced all-rounder, while the Big is the one for bigger waters and longer-range fishing.
It’s not a tiny, featherweight reel and it won’t be the cheapest option on the rack. But if you want a dependable longcast baitrunner that’ll handle clipped-up work, margins and open-water battles, this is a cracking bit of kit.

The full rundown
Everything you'll want to know about the Shimano Baitrunner XT-B Longcast Reel
There’s a lot to be said for a proper baitrunner on a carp reel. You’ve got the rods out, the spot’s clipped up, and you want the rig fishing without a carp feeling a brick wall the second it moves off. That’s where the Shimano Baitrunner XT-B Longcast comes in. It’s built for anglers who want long-range ability, sensible line capacity and a baitrunner system that’s easy to live with.
The first thing to get your head around is that this reel comes in two sizes. The Medium is the more balanced option, while the Big is aimed squarely at larger waters and longer-range jobs. They share the same basic approach, but they’ll feel different on the rod. Pick the right one and your setup should feel nicely matched. Go too big and you could be carrying more reel than the swim really needs.
The Medium model, code MBTRXTBLC, weighs 560 g. It holds 230 metres of 0.16 mm line and has a 5.3:1 gear ratio, bringing in 105 cm of line per handle turn. That’s a useful mix for general carp fishing, where you might be casting a decent distance one day and dropping a rig into the margins the next.
The Big model, code BBTRXTBLC, steps up to 720 g and holds 330 metres of 0.20 mm line. Its 4.6:1 ratio gives 110 cm per turn. That lower ratio suits a reel with more capacity and a more powerful feel, while the retrieve still shifts a healthy amount of line when you’re winding in from the far side of a lake.
Both models come with a 15 kg drag, so there’s no shortage of grunt when a carp decides to head for a snag or plough through a weedbed. You’ll still need to fish sensibly, of course. A big drag figure doesn’t mean you should clamp down like you’re winching a tractor. Set it to the situation, keep the rod working and let the reel do its bit.
The baitrunner arrangement is the main reason to look at this family rather than a standard big-pit reel. It’s dead handy when you’re fishing slack or semi-slack lines, especially from a bivvy swim where you want a bit of movement before the main drag takes over. The rear control lets you set the resistance, then you can engage the fighting drag when the bite-time moment arrives.
For long-range work, spool shape and line management matter just as much as raw capacity. The cold-forged aluminium spool is a strong, sensible choice, and the line reducers supplied with the reels are a proper bonus. You can match the amount of line on the spool to your needs instead of ending up with a massive coil of backing and loads of faff every time you respool.
There are 4+1 bearings in each reel and an XT-7 body. That’s not trying to be some daft, over-specced showroom queen. It’s a practical setup aimed at regular carp fishing, where smooth operation, a tidy clutch and dependable line lay matter more than collecting bearing numbers. Shimano’s name also gives the reel a reassuringly purposeful feel in this bracket.
The Big is clearly the one for serious water and bigger line choices, but don’t write off the Medium. For many anglers, it’ll be the bob-on option. It’s lighter, easier to live with for long sessions and still has enough capacity for a lot of UK carp fishing. Whichever you choose, spool it carefully, check the baitrunner before casting and keep the line clean around the lip. Do that and you’ve got a versatile reel ready for everything from a quiet margin bite to a proper long-distance bosh.

Our take
The angle
The smart choice here is picking the right size, rather than simply assuming bigger is better. The Medium offers a more manageable package for everyday carp fishing, while the Big brings extra capacity and a more powerful, long-range feel.
Both versions give you the same core appeal: a front drag for the fight and a separate baitrunner system for fishing slack lines or free-running rigs. That makes them properly versatile across a full season on the bank.
What you’re buying
A baitrunner with proper longcast intent
The XT-B Longcast combines a large, distance-friendly spool with Shimano’s separate baitrunner system. That gives you two useful modes: controlled free-spool while the rod is fishing, then a stronger front drag for playing the carp. It’s a particularly handy layout when you’re fishing slack lines, open water or a spot where the fish might move off before you’re on the rod.
The Medium is the more versatile choice for everyday carp work. At 560 g, it brings useful capacity without becoming a huge lump on the rod. The Big weighs 720 g and carries 330 m of 0.20 mm line, making it more suited to big reservoirs, long chucks and swims where line reserves really matter.
The cold-forged aluminium spool and supplied reducers make setup less of a faff. Reducers are especially useful if you don’t need to fill the whole spool with heavy line. They help keep the line profile tidy and let you tailor the reel to the venue, rather than fishing with loads of unnecessary capacity.
Worth knowing. Don’t choose the Big purely because it sounds more capable. Match the reel to the rod, line and water. A well-balanced Medium can be far nicer to fish with than a heavy setup that makes every cast feel like hard work.
Match it to your fishing
For anglers who want range and control
The XT-B Longcast makes sense for carp anglers who regularly fish beyond comfortable short-range chucking distance. The generous spool and longcast focus suit clipped-up work, measured casting and waters where a carp can take you a long way before it turns. The Big is the obvious pick when extra line and a beefier setup matter most.
It’s also a good fit for anglers who genuinely use a baitrunner. If you fish rods on alarms with a controlled free-spool setting, the system can make bite management simple and calm. Engage the main drag, lift into the fish and get your head in the game rather than faffing with a loose spool.
For snaggy swims, weedbeds and margin fishing, the 15 kg drag gives you plenty of muscle. That doesn’t replace good watercraft or sensible drag control, but it does give you a solid platform when a lump turns nasty. The Medium should cover most general situations; the Big is better when the venue demands more capacity.
Quick answers
The bits you’ll want to know
The Medium’s 5.3:1 ratio retrieves 105 cm per turn, while the Big’s 4.6:1 ratio retrieves 110 cm. In plain English, both bring in plenty of line, with the Big retaining a more powerful, long-range character despite its lower ratio.
The reels are not aimed at tiny commercial setups where you’re flicking a method feeder or small pellet into the near margin. They can do close work, but their strengths are capacity, baitrunner control and distance. If your fishing is mostly short chuck and small fish, a lighter reel will be less faff.
For setup, fill the spool evenly, use the supplied reducer if appropriate and check that the baitrunner is giving just enough resistance for the situation. You want the carp able to move off without feeling a locked-up spool, but not so freely that the line pours off in a daft tangle.
Worth knowing. The best performance comes from matching the reel size to your rod and line. The Medium is the safer all-round choice; the Big is the specialist option for extra distance, heavier line and larger venues.

Worth knowing
- The Big is a sizeable reel at 720 g and can feel a bit much on lighter carp rods.
