Who it suits
Is it right for you?
Great for
- Carp anglers using Flat Pear COG leads. The boom is built around the COG lead’s central grommet, so you get the proper intended fit rather than bodging together mismatched components.
- Anglers boating rigs into precise spots. The hooklink can be attached after the lead and boom are in position, which cuts down tangles and makes accurate placement much easier.
Maybe skip if
- Anglers wanting one universal lead-clip boom. This is a dedicated Flat Pear COG component, not a jack-of-all-trades boom for every lead shape in the box.
- Anyone fishing venues where leadcore is restricted. Always check the rules before using it, as some fisheries limit or ban leadcore-based systems.

Quick verdict
A cracking little COG upgrade
The Korda COG Boom QC Flat Pear is a neat way to build a lead-clip rig around the Centre Of Gravity lead system. The special swivel barrel sits in the lead’s central grommet, helping the lead do what it was designed to do while keeping the whole setup tidy.
The quick-change hooklink feature is the real draw. You can get the rig out there, boat it into position if needed, then attach the hooklink afterwards. Proper handy for accurate fishing, though you’ll need the matching Flat Pear COG leads to make the system work as intended.

Spliced leadcore, a dedicated QC swivel and a well-matched set of components give it a properly finished feel.
The central grommet connection and anti-tangle details are designed to keep the lead system stable and orderly.
Better placement and less hooklink faff can improve presentation, especially when boating rigs into precise spots.
The idea is straightforward and the quick-change hooklink feature is genuinely handy once the system is familiar.
Three complete booms and the matching components offer decent value, though the system only makes sense if you use Flat Pear COG leads.

The full rundown
Everything you'll want to know about the Korda COG Boom QC Flat Pear
Korda’s COG Boom QC Flat Pear is aimed squarely at anglers who like their lead systems doing a proper job, rather than just chucking a lead on the end and hoping for the best. It’s a spliced leadcore boom built for Korda’s Flat Pear COG leads, with a clever swivel arrangement tucked into the middle of the system.
The COG bit is the important bit here. The special swivel barrel is made to fit the central grommet in a Flat Pear COG lead. That means the lead sits around the connection point, rather than simply dangling from a conventional swivel. In plain English, the lead’s centre of gravity can work as intended.
That’s useful when you’re trying to get a rig settled neatly on the deck. A Flat Pear shape already gives you a stable, compact lead, and the matching boom keeps the connection tidy. On a clean hard spot, a light covering of silt or a firm patch, that sort of neat presentation can be just what you’re after.
The system is designed for use with lead clips, so it’ll feel familiar to anyone who fishes a standard carp setup. You’ve got the boom, lead clip and tail rubber arrangement, but with the COG lead fitting around that special barrel. It’s not some wild new rig that needs a degree in tackle mechanics. There’s a little learning curve, then you’re away.
Where it gets properly handy is the quick-change side of things. If you’re boating a rig into a tight spot, you can lower the lead and boom into position first, then attach the hooklink afterwards. That stops the hooklink flapping around the lead as it goes down, which is a common way to turn a lovely rig into a tangled mess.
That makes plenty of sense for margin work, weed holes, gravel patches and those awkward little dinner-plate spots you can’t reliably hit with a cast. Get the lead settled, keep the rig under control, then add the hooklink. It’s a small change to the routine, but it can remove a fair bit of faff when accuracy matters.
The leadcore construction also gives the boom a supple, tidy finish with a little weight to it. Used properly, that can help the terminal end lie down and reduce the chance of the boom kicking up off the bottom. The included anti-tangle sleeve adds another bit of insurance around the business end, keeping things orderly during the cast or drop.
There are three size options: 3/3.5oz, 4/5oz and 6/8oz. That covers the main Flat Pear COG lead range, from lighter close-range work through to heavier tackle for distance, flow or a bit more holding power. Pick the size that matches the lead you’re actually using, rather than buying on a whim.
Each pack contains three complete boom setups, along with three lead clips, three tail rubbers and three Kwik Links. That’s enough to sort a few rods or keep a couple of spares tucked away in the tackle box. Just remember this is a dedicated system. If you don’t already fish Flat Pear COG leads, the cost and compatibility are harder to justify. For the right angler, though, it’s a smart, tidy and very usable bit of terminal tackle.

Our take
The clever bit is underneath the lead
Rather than simply hanging a lead from a conventional clip, the COG Boom uses a special swivel that locates into the central grommet of a compatible Flat Pear COG lead. That keeps the lead’s centre of gravity doing the heavy lifting, helping it turn over and settle in the way Korda intended.
The QC arrangement also makes sense when you’re fishing from a boat or dropping rigs into awkward spots. Put the lead and boom in place first, then attach the hooklink once everything is settled. Less faff, less chance of the hooklink tangling round the lead while you’re lowering it in.
What you’re buying
A dedicated boom for a dedicated lead
The COG Boom QC Flat Pear is a spliced leadcore boom with a Size 11 quick-change swivel, an anti-tangle sleeve and the components needed to build three lead-clip systems. Its special swivel barrel locates into the central grommet of Korda’s Flat Pear COG lead, giving the lead a secure, purpose-built connection.
The available options cover 3/3.5oz, 4/5oz and 6/8oz Flat Pear COG leads. Match the boom to the lead range you’re using. Don’t try to force a heavy lead onto the lightest version and expect everything to sit bob on.
Worth knowing. The quick-change hooklink setup is most useful when boating or carefully lowering a rig. Set the boom and lead first, then attach the hooklink so it doesn’t wrap round the lead on the way down.
Best on the bank
For accurate carp fishing with less faff
This makes most sense for carp anglers already invested in Korda Flat Pear COG leads. It’s a tidy choice for margin spots, weed holes, gravel patches and any swim where you can place the rig rather than simply launching it into the blue yonder.
It’ll also suit anglers who like a repeatable setup across several rods. The pack gives you three matching booms, lead clips, tail rubbers and Kwik Links, so you can keep the rigs consistent and have a spare ready when a fish has given one a proper battering.
Worth knowing. Leadcore isn’t accepted everywhere. Check the fishery rules, make sure the system can discharge safely when required, and use it only when the venue allows it.
Quick answers
Everything else you need to know
Does it work with ordinary Flat Pear leads? No. The boom is designed around the central grommet found on Korda Flat Pear COG leads, so standard leads without that matching feature aren’t the intended partners.
Is it only for boat work? Not at all. You can fish it as a conventional lead-clip arrangement, but the quick-change feature really earns its keep when you’re lowering rigs accurately from a boat or into the margins.
Worth knowing. The pack gives you three complete systems, but you still need the compatible Flat Pear COG leads and your chosen hooklinks. Pick the lead weight to suit the swim, bottom and range rather than automatically reaching for the biggest lump.
