While both roles involve working with golf equipment, a Custom Club Fitter specializes in analyzing a golfer's swing and fitting clubs to optimize performance, often using advanced launch monitors and fitting systems. A Club Repair Technician primarily focuses on repairing, refurbishing, and maintaining golf clubs, such as re-shafting, re-gripping, and club adjustments. Both roles may require certifications like the Titleist Fitting Certification or club repair courses, and they often work in golf shops or pro shops. However, the Custom Club Fitter emphasizes personalized fitting and club customization, whereas the Club Repair Technician concentrates on club maintenance and repairs.
