The Dynamite Baits Milled Expander F1 Sweet is a versatile, high-attraction groundbait that has become a staple for the modern commercial angler. By milling premium expander pellets into an ultra-fine consistency and infusing them with the proven SwimStim Koi Technology, Dynamite has created a mix that triggers an aggressive feeding response while keeping fish interested without over-satiating them.
Weight: 750g bag.
Composition: Milled expander pellets.
Key Technology: SwimStim Koi Technology (premium feed triggers).
Consistency: Ultra-fine, lightweight.
Flavor Profile: F1 Sweet.
SwimStim Koi Technology: This unique attractant profile mimics the high-quality diet used in professional Koi farming. It is a scientifically proven feed trigger that creates a competitive feeding frenzy, encouraging even lethargic fish to start searching for food.
Ultra-Fine Consistency: Because it is milled from expander pellets, the particles are extremely fine. This allows the mix to create a distinct, active “cloud” in the water column that draws fish into the swim from a distance without providing them with large amounts of physical food to gorge on.
Versatile Application: This mix is incredibly flexible. It can be used as a standalone “slop” mix for shallow fishing, added to other groundbaits to increase their activity, or used as a “dusting” agent for maggots and pellets to add a layer of concentrated attraction.
Low-Feed Profile: Perfect for colder months or high-pressure venues where you want to keep fish active and hunting for bites without the risk of overfeeding them early in the session.
For the ultimate “slop” tactic, mix the Milled Expander with a relatively high water content. The fine particles will create a massive, active cloud as it hits the surface and descends through the water column. If you are fishing shallow, feed this mix regularly in small “pinged” amounts; the cloud it produces will mimic natural debris and keep F1s and Carp competing at the surface, often leading to rapid-fire bites.
Commercial Fisheries: The go-to mix for targeting F1s, Carp, and Skimmers, especially on venues where fish are used to pellet-based diets.
Winter & High-Pressure Tactics: Its “low feed” nature makes it an excellent choice when fish are feeding tentatively, as it provides attraction without the risk of bloating the fish.
Dusting Hookbaits: Use it to dust your maggots or expander pellets. This leaves a sweet, attractive coating on your bait that dissipates as it sinks, leaving a scent trail that leads directly to your hook.
Yes, absolutely. It is highly recommended to add it to your existing groundbait mixes to increase their “activity.” It breaks down much faster than traditional cereal-based groundbaits, making the overall mix more reactive and faster to pull fish into the area.
Yes, it works well in both cage feeders and method feeders. When using it in a feeder, mix it slightly on the “drier” side so that it explodes out of the feeder the moment it hits the water, creating an immediate plume of attraction around your hookbait.
The F1 Sweet profile is specifically designed for high-stocking-density fisheries. F1s, in particular, have a strong preference for sweet-scented baits, and the combination of this flavor and the Koi technology makes it one of the most effective ways to hold a shoal of fish in your swim for the duration of a match.
