Slinger

Slinger develops portable ball launchers and practice equipment for racket sports. Its best-known product is the Slinger Tennis Launcher, commonly referred to as the Slinger Bag, which combines a tennis ball launcher with a wheeled equipment bag rather than using the box-like design of a traditional ball machine.The Slinger approach is deliberately simple. Players can adjust launch speed, feed frequency and elevation, add an external oscillator for side-to-side feeds, and carry racquets, balls and other gear in the same unit. The company started with the aim of making personal ball machines more portable, affordable and accessible, and has since expanded its focus beyond tennis into other racket sports.
