✅ ‌Extendable Long Rod, Precision Upgraded‌: Equipped with an alloy extendable long rod, you can freely adjust the length according to the usage scenario. The longer draw distance provides sufficient acceleration space for the projectile, greatly increasing the initial velocity and range. It is paired with a professional laser aiming module, with a stable spot that does not drift. It supports independent adjustment of windage and elevation, with a spot offset of less than 1.2 cm within 50 meters. Whether it is a fixed target or a moving target, you can easily hit your target.✅ ‌Quick-Press Flat Band, Easy to Operate‌: It adopts a quick-press band structure, and it only takes 3 seconds to change the band, which is easy for beginners to operate. It is paired with high elasticity flat bands, which have light pulling force and fast recoil speed, resulting in higher projectile initial velocity. At the same time, the band interface is thickened and tear-resistant, so it is unlikely to break even with intensive practice, and it is durable.✅ ‌Alloy Body, Durable and Portable‌: The bow body is made of high-strength alloy and is integrally formed. Its bending stiffness is better than that of similar products, and it is unlikely to deform even if it falls accidentally. The telescopic design greatly reduces the volume after folding, and it can be easily put into the side pocket of a backpack, making it hassle-free to carry for outdoor travel and daily use.✅ ‌Thoughtful Details, Comfortable Grip‌: The handle is treated with an anti-slip finish, which is not cold in winter and not slippery in summer. Some models are also equipped with a level to assist aiming, which further improves shooting stability and reduces fatigue even after prolonged use.
