Once a speargun is loaded, the rubber bands store a massive amount of energy, ready to launch the spear at high speed. But how that energy is released makes all the difference.

Our speargun is designed to maximize rubber stretch along its entire length, from butt to head, ensuring the highest possible energy storage. But there’s more to the equation—rubber positioning. The bands touch the barrel only at their attachment points, reducing friction and improving energy transfer to the spear.

During contraction, the rubbers move directly opposite to the spear’s motion, counteracting its momentum and significantly reducing recoil. Less recoil doesn’t just improve accuracy—it also means less wasted energy, allowing more power to reach the spear.
