Power Band for Hand Spear / 145 cm / Made in U.S.A. ■ Overview For those who feel "slow!" when releasing a hand spear in the ocean. If you enjoy spearfishing, hearing "RIFFE / Amber" will make you say, "The excellent stretch and unique tenacity are in a class of their own compared to other manufacturers!" This is a gem, but RIFFE has two types of hand spears called "CARBON FIBER POLE SPEAR": A) Total length 9 feet (approx. 2.7m) with a 3-piece construction B) Total length 6 feet (approx. 1.8m) with a 2-piece construction The aforementioned hand spears use a 3/8" power band as a genuine product. The characteristics of amber, which is made by dipping natural rubber (※ raw kneading), boast the best elongation rate among rubbers. However, it is a well-known fact that it is inferior in weather resistance, chemical resistance, and durability, but there are also hand spear users who stubbornly support "I only use amber!". Various power bands handled by RIFFE are products manufactured by ordering from companies other than their own. This product is from the only latex tube manufacturer in the United States, founded in Ohio in 1960. In addition to amber, they also supply natural rubber mixed with carbon, etc., using a unique "kneading" process, commonly known as special-kneaded black rubber, to manufacturers such as RIFFE, which handles spearfishing-related products worldwide. Rubber with a thin tube and a large inner diameter like "macaroni," or rough products made in China, affect the "ejection speed" so much that they cannot fully demonstrate the original performance of the hand spear. Outer diameter size: 3/8" (※ 9.525 mm in millimeters) ■ From Mr. Toyota, residing in Miyakojima, Okinawa Prefecture, who uses this product "It's a good rubber with a beautiful amber color. My hand spear is 4.4 m / 810 g, but it's equal to or better than RIFFE's 13 mm single pull, and it's easier to pull," he commented.
