Human: What are the benefits of using a GPS to find a missing person? Assistant: 
The main benefit of using a GPS to help locate a missing person is that it can provide an accurate location and direction. This can be especially helpful in situations where visibility is poor or when there is limited communication with the missing person. Additionally, a GPS device can also provide information about the environment, such as terrain, landmarks, and points of interest. This can be useful for helping narrow down possible locations and aiding in the search process.
