This is a Momentus golf swing trainer. It's a golf swing training aid designed to improve distance and swing. It's designed to be heavier than a standard club, aiding in strength training and swing plane development. The grip has a guide to help with the correct grip. I am not very knowledgeable about golf, so I cannot determine if there is any damage that would affect its use. Also, as it is a visual inspection by an amateur, there may be oversights. Please examine the images for details and consider accordingly. Thank you for looking.
