USA Latex OPTIBAND speargun rubber is the product of over 40 years in the speargun rubber manufacturing industry. The OPTIBAND formula is a result of working closely with Speargun manufacturers and Spearos to create a super smooth high stretch speargun rubber. OPTIBAND is made from quality natural latex and is formed using a dipping process for superior quality. OPTIBAND and Railguns USA Latex’s OPTIBAND is a band that is less resistant to load than other formulas and has a smoother release of power which helps to reduce recoil. Increased power can be achieved by increasing the power stroke of the band, the high stretch formulation allows for a shorter band to be used while remaining practical to load. This has an advantage over traditional speargun rubbers that rely on highly resistant rubbers to generate their power which often results in excess recoil and reduced accuracy. OPTIBAND and Rollerguns USA latex’s OPTIBAND improved is much more suited to Rollerguns than the traditional USA latex which was prone to collapse under the increased pressure of a Rollergun. OPTIBAND allows for up to 350% stretch whilst retaining its structural integrity. OPTIBAND Care Natural Latex should be stored away from high heat, UV and ozone-generating devices such as motors. If stored correctly in a container away from these elements the rubber will last for years.
