Remote training devices are tools used to train animals or individuals from a distance. These devices often include features like sound signals, vibrations, or lights to communicate commands or cues without the trainer being physically present. They are commonly used in dog training, where trainers can reinforce positive behavior or correct unwanted actions remotely. These devices can also be utilized in various fields, such as sports coaching or education, allowing instructors to provide feedback and guidance without being on-site. Examples include remote control collars for pets and smartphone apps for fitness training, enhancing the training experience through technology.
