The Bushnell Pro XE rangefinder is legal for use in most golf tournaments and events, including those sanctioned by the USGA (United States Golf Association) and R&A (The Royal and Ancient Golf Club of St Andrews). The device is designed to measure distance only and does not provide any slope or wind information, which are prohibited in some tournaments. However, it’s always a good idea to check with the tournament or event organizers to confirm any specific rules or restrictions on the use of rangefinders before bringing one to the course.
