Which of the following is NOT categorized as a throw device?

A throw device is designed to be utilized by rescuers to provide assistance to individuals in distress in water. These devices are typically thrown to a victim to help pull them to safety. In this context, the shepherd's crook stands out because it is not thrown. Instead, it functions as an extension tool that helps reach a person safely from the shore or the bank of a waterway.

Throw bags, throw balls, and life rings are all designed to be thrown to victims in water rescue situations. Throw bags contain a length of rope that can be easily deployed to a victim, throw balls are typically weighted objects that can also be thrown, and life rings are buoyant devices that provide immediate flotation for rescuers to toss. On the other hand, a shepherd's crook, which is usually a stick with a hook on the end, is used to grasp or maneuver objects rather than being thrown. This highlights why it does not belong in the category of throw devices.
