This launcher has advantages in using the sound and throwing your marks for better placement a long with of course the ability to launch them as well. The bases are used for target markers in both getting the dog to run out straight, or to give the dog a visual picture on come in whistles with a hand signal. In this video, the dog is released with a bumper in his mouth, and then he exchanges bumpers so that piles do not necessarily have to be used, and because practicing with a bumper in his mouth makes for more concentration in the dog hitting his targets and taking casts.
