Speargun Shafts & Tips

Of course! At decathlon.com.gr you will find a specialized variety of speargun shafts & tips, designed to cover every type of underwater hunting—from shallow-water and hole fishing to demanding blue-water ambush hunting at great depths. Choose among premium quality speargun shafts made from highly durable materials such as stainless steel (inox) and heat-treated tensile steel, which offer maximum resistance to bending from rock impacts. The Decathlon collection includes shafts with notches or shark fins for easy and safe loading, available in various lengths and diameters (such as 6.25mm, 6.5mm, or 7mm) to match the length of your gun perfectly. Depending on your style of fishing, choose single-piece shafts (Tahitian) with a built-in flopper for top speed in open water, or threaded-tip shafts to easily change tips (single-flopper, double-flopper, prongs, or multi-prongs) when hunting in caves and dens.

The ideal material for a speargun shaft depends on your fishing style and whether you prioritize resistance to bending or shot speed. For most underwater hunters, stainless steel (inox) is the most reliable all-around choice. Stainless steel speargun shafts & tips offer excellent resistance to saltwater corrosion and do not rust easily. They are ideal for hole and shallow-water fishing because they can withstand rock impacts without warping, maintaining their sharpness. If, on the other hand, you practice demanding ambushes for large catches, the ideal material is heat-treated spring steel (such as Sandvik style). Due to its special tempering, it has incredible memory (elasticity); it bends during a fight with a powerful fish but returns immediately to its original straight line. It offers maximum speed and penetration, although it requires a thorough rinse with fresh water after each dive to protect against oxidation.

To find the correct thickness, think of it simply: a thin shaft (6.0-6.25mm) for explosive speed with a single band, a medium shaft (6.5mm) as the absolute all-around choice for the majority of guns, and a heavy shaft (6.75-7.0mm) for maximum impact power with multi-band setups. Of course, these rules are not set in stone, as many spearfishers experiment with intermediate thicknesses to find their own personal "golden ratio" based on their gun's recoil. In any case, make sure the thickness is compatible with your gun's trigger mechanism and muzzle. To ensure perfect accuracy on every shot, don't forget to combine your new speargun shaft & tip with appropriate compatible speargun bands, as well as with a pair of durable spearfishing gloves that will make loading a breeze!

For hunting large fish, the two most suitable choices are single-piece shafts (Tahitian) with a double flopper and detachable slip tips. Tahitian shafts with a double flopper are ideal for large bottom fish like groupers, because the floppers open wide like an anchor once they pass through the catch, while their single-piece construction offers maximum rigidity to prevent the shaft from bending. On the other hand, detachable slip tips are the ultimate solution for large pelagic fish like amberjacks, since they detach from the shaft adapter after penetrating the fish and remain connected only via an ultra-durable Dyneema or steel cable. In this way, the fish pulls directly on the reel line, eliminating the possibility of using the shaft as a "lever" to tear itself free. Whichever setup you choose, make sure to bring along a durable fish stringer / keepnet to carry your large catches comfortably and safely back to shore!

No, shafts are not universally compatible with all spearguns. To make sure your new speargun shaft & tip fits your gun perfectly, you need to check three basic things: whether your speargun is a band or pneumatic model, whether your muzzle permits shark fins or only notches, and whether the shaft thickness sits correctly in the barrel's track. A wrong choice can ruin your accuracy or fail to engage with the trigger mechanism entirely. For peace of mind, don't forget to check the rest of your gun's consumables, replacing worn speargun bands or renewing the shooting line on your reel, so your setup is fully ready and safe for your next dive!
