The phone chest mount is designed for a variety of usage occasions. It is particularly useful for activities such as skiing, fishing, biking, and motorcycle riding, where you may need both hands free while still being able to easily access your phone. This makes it ideal for recording your adventures or providing commentary for video content creation. However, it is not recommended to use the mount for shooting videos while jumping or running, as the anti-shake function of your phone may not be able to compensate for the movement. When activated, the anti-shake function of your phone can significantly improve the quality of your video recordings.
