Sonubaits SpikeUm Wafter (8mm)
While the famous BandUm range revolutionized hookbaits for those who love a bait band, theres always been a group of anglers who prefer the speed and precision of a bait spike or bayonet. The Sonubaits SpikeUm Wafter is the direct answer to that demand. These arent just re-shaped BandUms; 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 SpikeUm 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 SpikeUm is the first thing to fly into its mouth, leading to more aggressive takes and better hook-ups.
Key Features & Benefits
-
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 doesnt 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, SpikeUms 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.

Why the 8mm Size?
The 8mm SpikeUm is the utility player of the range. Its 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 its 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.
Gerrys Pro Tip
At Gerrys, weve seen a huge shift toward spikes because theyre just so much faster when the fishing is thick and fast. My top tip for SpikeUms: 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 longersometimes through 3 or 4 fish! Also, if youre 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.
Frequently Asked Questions
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 its 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 BandUm 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: SpikeUms 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.
