What are the best practices for using a floating strap with underwater cameras to prevent them from sinking?

To prevent underwater cameras from sinking, it is best to use a floating strap that is securely attached to the camera. Make sure the strap is strong enough to support the weight of the camera and that it is properly adjusted to fit snugly around your wrist or arm. Additionally, always test the floating strap in shallow water before using it in deeper waters to ensure it works effectively.
