A tune-up drill is a series of land or water blinds run on successive days.

Tune-up drills can be useful for at least 4 reasons:

1. They get your retriever comfortable with multiple blinds
2. They teach your retriever go straight in a blind corridor.
3. They are useful to teach your retriever advanced blind concepts.
4. They help you develop as the handler to be proactive and reactive to keep your dog in a tight blind corridor.
