Boilie Rocket A completely new concept in bait delivery! The Boilie rocket's clever design allows the angler to cast baits to a pin point target area, while not spilling or wasting any in the process. The deep finned rocket design flies very accurately and only opens the trap door on contact with the water surface, allowing 100% of the load to be instantly released in the exact targeted spot. The Boilie Rocket is suitable for boilies up to 15mm diameter, and all other dry particle baits like pellets. It also works brilliantly with maggots and casters.
