What penalty will a golfer incur after hitting a golfer 's ball during a putt ?
Players who buy clubs , balls and other golfing equipment at retail stores and do not modify them before use will generally be in compliance with these rules ; however , companies can and do make non-conforming equipment such as novelty golf balls and " long - drive " clubs ; players should examine the packaging of any equipment to determine that it is , or is not , suitable for sanctioned play by strict rules .
