Ultimate Dive 72cm Rubber Spearfishing Harpoon Diameter Highly Stretchy and Power NATURE Tube Rubber Spearfishing Harpoon Ultimate Dive (9.5mm /

✅ [Harpoon rubber that combines ease of pull, initial velocity, and power] When choosing harpoon rubber, the key factors are "ease of pull (ease of use), initial velocity (speed), and power (power)." The rubber's characteristics are "stretch and flexibility." Ultimate Dive's sling rubber is made from 100% natural rubber, NATURE. This high-quality, pure natural rubber provides excellent stretch and tenacity, resulting in high initial velocity and power when released. Its high elasticity allows the harpoon to maintain its power while heading toward the target fish. Storage: Avoid direct sunlight and high temperatures and humidity. Store in a cool, dark place. This can cause deterioration, such as tearing. ✅ [Rubber Length and Selection] Example: When using two Ultimate Dive 90cm shaft poles, it is best to grip the 72cm rubber at 1.5 to 2 times its normal length. With this specification, gripping the shaft about 5 to 10cm from the metal fittings at the end and middle pole connections is most effective. Note: Because this rubber is powerful, grip strength may vary. In that case, we recommend using a rubber grip and diving gloves to find your best fit. Another size, the 84cm rubber, is good for connecting Ultimate Dive harpoon sets longer than 3m. Product Details and Specifications: Rubber diameter: 9.5mm, total length: 72cm (rubber only), mesh cord, 100% natural rubber (NATURE). Seawater salt and metal do not mix well. Thoroughly drain the seawater from the harpoon tip, shaft pole, sling rubber, and other accessories, rinse with fresh water, and allow to air dry. Leaving seawater on or in the sling can cause the metal parts to rust. ✅ [About firing a harpoon] If the distance from where you grip the rubber to the tip of the harpoon is long, it will be difficult to handle. In that case, make the sling rubber a little longer. Conversely, if the distance to the tip of the harpoon is short, you will have to get close to the fish to release it. In this case, adjusting it when you are close to the fish, such as when shooting a hole, will make it easier to handle. ✅ [Ultimate Dive] Founded in 2016, Ultimate Dive is a brand specializing in spearfishing.
