The SNAGazoo is designed to develop the proper swing positions for a pitch shot. When the new learner swings away to the 9 o'clock position, their target arm and the SNAGazoo form an "L". If this is done correctly, the device will then produce a sound indicating correct position.

If done incorrectly, then the device makes no sounds. This allows the new learner to self-correct when practicing this swing. The device comes with extra noisemakers (zoos).
