Blue Fox Vibrax size 6: the biggest spinner in the range for catfish
One lure, endless conditions. CarnaFish reads your spot from a photo so you are not just guessing.
Search for a "Vibrax Giant" on any tackle site and you'll find nothing official: Blue Fox has never made an XXL version of its cult spinner. The name still circulates a lot in catfish circles, though, for a specific reason worth knowing before you order the wrong size expecting something bigger.
The "Vibrax Giant" myth
The Vibrax Original range officially tops out at size 6, which weighs 18 g for a blade around 6-7 cm. There's no size 7 or 8 for this line at Blue Fox — what catfish anglers sometimes call a "Vibrax Giant" is actually either the size 6 itself, or a tandem rig of two spinners run together, a trick many big-predator anglers use to get more flash and displaced water than a single spinner, even at size 6, can produce.
Size 6, the actual ceiling of the range
So don't look for anything bigger from Blue Fox: size 6 is the starting point, not a compromise. Its blade spins at low speed the moment it hits the water thanks to the 45° rotating axis, and the two-part metal body houses rattles that add a low-frequency sonic vibration — a real plus for a fish that hunts by ear as much as by sight, catfish included.
Tandem rigging: how catfish anglers fake the size
To get a bulkier profile without switching brands, the most common rig threads two size-6 Vibrax spinners in series on a strong leader, separated by a small intermediate swivel to stop the blades tangling. The result: double flash, doubled vibration, and an overall silhouette far wider than a single spinner — no "Giant" model required, because it never existed in the catalogue.
A spinner that isn't turning catches nothing, however big it is. Before blaming the size, always check the blade spins freely at the drop — a bent shaft after a snag is the most common and least visible failure.

Why the blade turns (and why you should never go too slow)
The Vibrax blade is built to start spinning within the first few turns of the reel, but it needs a minimum speed to keep going. Retrieving too slowly stalls the blade, which then stops spinning and vibrating — the worst outcome on a spinner, since its whole appeal rests on that motion. A medium, steady retrieve works better, with short pauses if needed rather than slowing down continuously until the blade stalls.
Gear for casting an 18g spinner at catfish
- A heavy rod, 2.40 to 2.70 m, able to handle repeated casts of a modest weight but violent fights.
- Braid, 40-60 lb, on a solid reel.
- A strong fluorocarbon or coated leader around 80-110 lb, with a quality swivel clip to prevent twist — essential on this kind of rotating lure, even more so in a tandem rig.
Colour by water clarity
- Stained water: brass or copper, warm tones that carry well in low-visibility water.
- Clear water: silver, for a more subtle, natural flash.
- Murky water: fluorescent orange or chartreuse, to maximise contrast when visibility drops close to zero.
A spinner is a fast-prospecting lure, complementary to slower approaches like the Sandra 23cm: alternate between the two depending on whether you're covering a stretch quickly or working a specific spot slowly.
Knowing which spot suits a fast spinner is exactly what CarnaFish helps figure out: a photo of the spot, and the AI suggests a zone and a prospecting technique suited to the day's conditions.

FAQ
Does the Vibrax Giant actually exist at Blue Fox?
No, it's not an official model. The Vibrax Original range tops out at size 6 (18 g). The "Giant" term comes more from how catfish anglers use it, particularly through the tandem rig of two spinners.
What's a tandem rig with the Vibrax?
It's threading two size-6 Vibrax spinners in series on the same leader, separated by a small swivel. This doubles the flash and vibration, for an effect comparable to a much larger spinner.
What retrieve speed works best with the Vibrax?
A medium, steady speed, enough to keep the blade turning continuously. Retrieving too slowly stalls the blade, which cancels out the lure's whole sonic and vibrational appeal.
Do I need an anti-twist swivel with the Vibrax?
Yes, always, and even more so in a tandem rig. Without a quality swivel clip, the blade's rotation quickly twists the leader and complicates the next casts.
What gear should I use to fish catfish with a size 6 Vibrax?
A heavy 2.40-2.70 m rod, 40-60 lb braid, and a strong fluorocarbon or coated leader around 80-110 lb, with a reliable swivel clip.
What colour Vibrax should I use in murky water?
Fluorescent orange or chartreuse, for maximum contrast when visibility is very reduced. Save silver for clear water and brass or copper for slightly stained conditions.
