Uniform resistance of six-leaf water slurry: Four-leaf water slurry is added on the basis of traditional two-leaf water slurry, which effectively relieves the sense of frustration, the water resistance power is smoothly output, and the true touch of the paddle across the water surface is reproduced.18L aviation-grade polycarbonate water tank: polycarbonate water tank made of aviation-grade materials has the characteristics of high light transmission, impact resistance and corrosion resistance, and can provide greater resistance output. Not only the water in the tank is clearly visible, but also can be guaranteed for a long time. The water quality is fresh and not easy to deteriorate.Built-in scroll spring: even and smooth between stretching. The scroll spring device effectively solves the problem that the elastic rope is easy to fall off due to the long-term stretching elastic force, which increases the service life of the elastic rope, shrinks freely, and the experience is smoother.Foldable design, does not take up space: there is a folding lock on one side of the machine rail, which can be folded gently with one hand to complete the folding action, which is simple, fast and convenient.LCD screen: In order to monitor your exercise and get the best results, the rowing machine is equipped with a small computer with an LCD display, where you can view your performance, exercise distance or calories burned at any time.
