While the famous Band’Um range revolutionized hookbaits for those who love a bait band, there’s always been a group of anglers who prefer the speed and precision of a bait spike or bayonet. The Sonubaits Spike’Um Wafter is the direct answer to that demand. These aren’t just re-shaped Band’Ums; they have been engineered with a specific texture that is soft enough to be spiked without splitting, yet tough enough to stay on through a 100-yard cast.
Like all true wafters, the 8mm Spike’Um is designed to float on its own but sink slowly under the weight of your hook and spike. This creates a “weightless” presentation that hovers just above your Method or Hybrid feeder. When a fish sucks at the bait, the Spike’Um is the first thing to fly into its mouth, leading to more aggressive takes and better hook-ups.
Spike-Friendly Texture: Specifically formulated to be “soft-yet-resilient.” You can push a bayonet or spike into these pellets repeatedly without the bait crumbling or splitting.
Critically Balanced Buoyancy: Carefully calibrated to counteract the weight of the hook. It doesn’t sit like a heavy “brick” on the bottom; it “wafts” naturally with the movement of water.
Long-Term Consistency: Unlike some wafters that lose their buoyancy once the tub has been open for a few weeks, Spike’Ums are designed to maintain their “waft” long-term.
High-Attraction Flavors: Available in the full legendary Sonubaits lineup, including the new Salted Caramel and the classic Chocolate Orange.
Visual Standout: Each tub contains a mix of colors within that flavor profile, allowing you to switch between subtle and “hi-viz” options instantly.

The 8mm Spike’Um is the “utility player” of the range. It’s the perfect size for:
Standard Method Feeder Work: It provides a visible target in the center of your groundbait mound without being so large it spooks cautious fish.
Hybrid Feeders: Because it’s spiked, it stays exactly where you put it on a Hybrid feeder, even when navigating the “trap” through deep water.
Targeting Big Bream: Bream love a sweet, wafting bait, and the 8mm size is a perfect “mouthful” for a quality slab.
“At Gerry’s, we’ve seen a huge shift toward spikes because they’re just so much faster when the fishing is ‘thick and fast.’ My top tip for Spike’Ums: Use a fine-gauge bayonet. While the bait is designed to be soft, a thinner spike creates a smaller hole, which means the bait will stay on for even longer—sometimes through 3 or 4 fish! Also, if you’re fishing in very shallow water, try the Fluoro or Chocolate Orange versions. The visual pop combined with the wafting movement is often too much for a curious carp to ignore.”
Q: Do I still need to check them in water?
A: Yes! Always. Different hooks and different spikes have different weights. You want the bait to sink slowly and rest just above the hook shank. If it’s floating too high, move to a slightly heavier hook or add a small shot to the hair.
Q: Can I use these in a bait band?
A: Technically, yes, but the texture is optimized for spiking. If you prefer banding, we recommend the Band’Um Wafter range, as the dumbbell shape is specifically designed to lock into a band.
Q: Will they split if I use a large spike?
A: Spike’Ums are much more “forgiving” than standard hard pellets or boilies. However, if you use a very thick, old-fashioned spike, you might see some wear. Modern, thin-wire bayonets are the perfect partner for these baits.
Q: How do I keep them fresh?
A: Just keep the lid screwed on tight! The unique formula is designed to stay “spikable” for a long time, but keeping them out of direct, baking sunlight will help maintain that perfect texture for the whole season.
