To bait with boilies, the key accessory is the boilie throwing tube. It is faster and more solid than a
slingshot but on the other hand it only serves for boilies. In the 90s the brand "Cobra" was so present on the market that some still refer to a "cobra" to designate a boilie throwing tube, otherwise in English we can also find the name "throwning sick". The principle is very simple, you make a movement with your arm so that the boilie gains speed in the tube and this speed expels it and allows it to reach a certain distance to fall back into the water. Getting the hang of it is not innate, it will require a bit of habit, but the best advice to start would be to aim high at the sky, if you aim at the water you generally don't throw far. There are several shapes of tubes, from the perfectly straight tube which gives less speed to the baits, to the one with a complex S shape, or with just an elbow at the end or even a banana shape, you will need to adapt your gesture to the shape, but this will come naturally with training. You will also have the choice between several materials: thin PVC, thick PVC, aluminum and carbon each with their advantages and disadvantages. Thin PVC (less than 1 mm thick) is very light, on the other hand fragile, in the sun, to crushing and even to powerful throws in repetition. Thick PVC becomes heavier but stronger. We continue with aluminum, heavier, but indestructible. Finally carbon, the last one to arrive will give you unparalleled rigidity and lightness, but be careful with the price and shocks, some are even sold with a cover. For the diameter always take one or two mm more, but not too much because it unnecessarily weighs down, for example 22 mm is perfect for throwing 20 mm. Finally, some options are welcomed such as a comfortable handle or an opening to place the baits near the hand. The most well-known boilie throwing brands are Fox with its Range master range, Nash, Starbaits and Carp Spirit.
