The Uneekor EYE XO requires a minimum space of 12 feet by 10 feet. You will also need a ceiling height of at least 9 feet. This is because the EYE XO is mounted above the golfer, and it needs to be able to track the clubhead and ball throughout the entire swing.
If you have a smaller space, you may be able to use the EYE XO by using a smaller net or by hitting off of a mat. However, you may experience some limitations in the data that the EYE XO can collect.
