Our unique latex formulation and dip manufacturing process delivers radical modulus strength. The power curve increases as bands are stretched for optimum performance. Special anti-oxidants help protect against harmful U.V. rays, prolonging sling life. Wishbones are made of 302 stainless wire and provide superior strength and durability. 600 series bands feature a 1/2" outer diameter and are the standard band for our Carbine series of spearguns. They are also a great choice for divers looking for an easier band "pull" when loading.
