• Portable and Movable: Compared with the wall-mounted height jump tester which can only be fixed on the wall, the floor-standing height jump tool is equipped with a plastic base with wheels.When you use it, water can be injected from the plastic base inlet with wheels or sand to add to the base weight, making the vertical jump coach more stable and easy to shake. The wheels on the base allow you to move easily
• Stable and Accurate: This sport vertical jump tool weighs 10 pounds before water is not injected, and weighs 35 pounds after the base is filled with water or sand, making it difficult for trainers to shake or move easily when using it. You can also add extra weight to the base to make the tester more stable. In addition, the scale on the stainless steel shaft of the vertical measuring instrument is laser cut, and the size is clear and accurate
• Pole-reset and Anti-cut: The blade is made of ABS material and is not easy to deform when pat by hand. The corners of the blade on the vertical jump meter are rounded to prevent cutting your hands during measurement. After the jump measure, you can use the reset lever to reset immediately
