HAOYI Telescope and spotting scope vibration is caused by windy conditions, an unsteady mount or tripod or even an accidental bump to the instrument, and results in reduced image quality. The three Vibration Suppression Pads will reduce vibration time by almost and decrease vibration amplitude. The pads fit between the bottom of the tripod legs and the ground, a simple and functional solution to the problem of image disturbance. They work on any surface: grass, dirt, concrete, asphalt, wood, etc., for both telescopes and spotting scopes.
