PSE is the largest privately owned archery equipment manufacturing company in the country, devoting their time to the develop ... ment of the most advanced compound bows and related equipment ever produced. Born with humble beginnings in a 700-square foot building in Mahomet, Illinois, PSE was one of the first five companies to obtain licensing under the Allen Patent for compound bows. Of the original five, PSE is the only company still manufacturing compound bows. In 1982, PSE moved its entire operation - employees and all - to Tucson, Arizona, incorporaing the manufacturing and production in one location. As a sharp contrast to the modest 700 square foot original location, PSE's corporate offices, factory, and pro shop facilities practically fill an entire city block in central Tucson. Archers can count on PSE to bring advanced manufacturing techniques to the industry. PSE was one of the first companies to machine bow risers and accessories from solid aluminum. PSE pioneered the four stage forging process for bow risers to create strong, lightweight bows. PSE, as the industry's leading manufacturer, holds twenty patents for bow design and archery products. These improvements spread throughout the industry to everyone's benefit, not just PSE. "Research and development are the most expensive stages in manufacturing," Pete Shepley explains, "but we're committed to it and to making the whole industry grow, not just our slice of the pie." read more
