Slinger - The Most Portable Tennis Ball Launcher by Joe Kalfa — Kickstarter

Do you have an active dog who always wants to play? If so, automatic ball launchers are the perfect fit for both you and your dog. In addition to fitness, auto ball launchers also enable beneficial mind stimulation, training, and independence in your dogs. Automatic dog ball throwers work by dropping a ball usually a tennis ball into the opening of the device which then launches the ball anywhere from 10 to 30 feet! Most ball launchers can adjust the distance so that they can be used both indoors and outdoors. Some models, such as the iFetch ball launcher, can be used with either batteries or an AC power cord which is amazing, allowing you to use the power cord when indoors and use batteries when outdoors so you do not need to run an extension cord.
