A Satellite Emergency Notification Device (SEND) is a portable device that allows users to send emergency alerts via satellite communication. These devices are particularly useful in remote areas where traditional cellular networks are unavailable. Users can transmit their location and a distress message, ensuring that help can be dispatched even in the most isolated locations. SENDs are often used by outdoor enthusiasts, such as hikers and campers, as well as by professionals working in remote environments. Many models also include features like GPS tracking and two-way messaging, enhancing safety and communication during emergencies.
