How thick and long is the rubber band of the long pole slingshot.

3-4 mm. The rubber band used in common long-rod slingshots is generally 3-4 mm in diameter and about 50-60 cm in length. If you want to increase elasticity, you can choose a slightly thicker rubber band or a longer rubber band. However, it should be noted that the rubber band is too long or too thick, which may lead to excessive bending or out of control of the slingshot rod and increase the risk of use.
