Developed in conjunction with match fishing legends Des Shipp and Tommy Pickering, the Sonubaits F1 range has completely revolutionized modern fishmeal-based groundbaits. Specifically engineered for commercial fisheries where F1 hybrids and carp are the primary targets, this specialized Dark version is an absolute essential for clear water conditions, winter leagues, or when targeting wary, hard-fished silverfish and skimmers.
By combining a unique, high-potency sweet attractor blend with premium crushed pellets and high-grade marine fishmeals, Sonubaits has created a mix that triggers instant competitive feeding “from the whistle.” The dark profile offers a vital tactical advantage: it blends seamlessly with the lake bed, giving fish the confidence to settle and feed over your area without fear of being silhouetted against a bright background. It is incredibly easy to mix, binds beautifully to a Method or pellet feeder, and breaks down rapidly on the deck to create a highly concentrated zone of attraction without overfeeding.
Color: Deep Charcoal / Dark Brown (Optimized for clear water and wary fish)
Core Ingredients: Premium crushed pellets, high-grade marine fishmeals, and a secret sweet attractor blend
Texture: Fine, uniform particles that create an inactive, rapid-breakdown mix when dampened
Target Species: F1 Hybrids, Commercial Carp, Skimmers, Bream, and Roach
Application: Method feeder, pellet feeder, balling-in, cupping-in as a cloud/slop, or open-end cage feeders
Pack Size: Standard high-value match bag
Winter and Spring Match Formats: The dark formulation is lethal in cold, clear water. It prevents fish from spooking over a bright patch of bait, holding skimmers and F1s in your swim for prolonged periods.
Commercial Method Feeder Tactics: Perfect for packing tightly onto a Method or pellet feeder. Its ingredients ensure it clings securely during high-impact casts but explodes off the frame the second it settles on the bottom.
Margin Cupping for F1s & Carp: Ideal for cupping in tight against the reeds or bankside drop-offs. It can be mixed damp to form a tight, heavy carpet or over-wetted into a sloppy, high-viscosity cloud to draw fish down from the upper water layers.
Pro Tip from the Gerry’s Fishing Team
While Sonubaits F1 Dark can be mixed successfully on the bank, it performs at its absolute best when mixed the night before your session. Empty the bag into a large bucket, add water gradually while whisking, and intentionally leave it slightly over-wetted. Over the course of the night, the crushed pellets and fine fishmeal particles will fully absorb every drop of moisture, plumping up perfectly.
Before your match or session begins, pass the groundbait through a fine riddle. This injects air back into the mix, breaking up any clumps and resulting in a flawlessly fluffy, consistent texture that creates a highly active, fast-breaking bed of feed directly around your hookbait.
Why choose F1 Dark over the standard original F1 groundbait?
The original F1 mix is quite light in color, which is fantastic for summer conditions when water clarity is low. F1 Dark is specifically designed for times when the water clears up (such as autumn, winter, or early spring) or for heavily pressured venues where fish are terrified of sitting over bright, high-contrast patches of bait where predators can easily spot them.
Is this groundbait active or inactive once it hits the water?
When dampened correctly, the fine fishmeal particles create an inactive mix. This means the bait stays pinned hard to the lake bed rather than fizzing or rising through the water column, forcing the fish to keep their noses down on the bottom directly over your hookbait.
Can I use this mix to create a sloppy cloud for pole fishing?
Yes, absolutely. By adding a significant amount of extra water, F1 Dark breaks down into a perfect, uniform slop. This is an incredibly effective tactic when cupping in shallow margins or presentation lines for F1s, creating a dark, scent-rich cloud that hangs in the water column.
Can I mix this with other groundbaits?
Definitely. It is highly versatile and blends brilliantly with other Sonubaits mixes. A highly popular match-winning cocktail is a 50/50 mix of F1 Dark and Sonubaits Thatchers or Supercrush Expander to add a bit more mechanical action to the bed of bait.
