Trainer base is a multifunctional device. You can attach a dummy block, a radar hoop, and a leaf component to measure the reaching jump. These 3 elements allow you to organize effective training. You can also organize a number of attractive games for children on this basis. Just put out some device and see what happens.
The new database is even more functional and secure. Built on a triangle base, it provides great stability when held together with only four screws. Its stability is emphasized by the fact that it stands on feet, not on wheels, and at the same time it is mobile and agile. A slight tilt is enough for the wheels to rest on the ground and driving in any direction and at speed is fun. The real revelation is the lifting of the movable arm, which raises up without any resistance, but automatically brakes when moving down. This prevents sudden lowering when the eccentric lever is released. Practically one lever regulates the downward movement of the arm. The upward movement does not require unlocking the eccentric. The movable arm has a scaled sticker showing the lifting height of the attached component. This is particularly important when measuring the reach jump using a leaf device. There is a handle at the bottom of the arm that makes it easier to lift the mounted device.
The device comes with installation and use instructions.
