A vertical leap measuring device is provided. The device comprises rotatable blades mounted to a support mechanism mounted to a mount, which can be mounted to a support structure. The support mechanism is configured to rotate with respect to the mount between an operable position and a stored position. In the operating position, the blades are configured to rotate about the support mechanism in response to user-applied force. Once displaced, the blades can be automatically reset to an original position by operation of a remote-controlled transmitter that commands positioning members to return displaced blades back to their original position. The blades are made of a combination of flexible and non-flexible members. |
