The SportDOG Brand® Launcher Receiver can be fitted to most brands of bird launchers or throwers and also works with our Launcher Basket. The system can be used to train retrievers to remain steady and mark falling birds. It can also be used in pointing dog training to reinforce steadiness when a bird flushes. To add realism to training situations, the Transmitter can signal the Receiver to emit the sound of a duck quack, pheasant cackle, or shotgun report.
