An individual enrolled in the Project Lifesaver Program is referred to as a client. Clients wear a unique pre-programmed one ounce battery operated transmitter either on their wrist or ankle at all times. This transmitter will emit a unique tracking signal every second, 24 hours of the day.
When a client goes missing, it is up to their caregiver to call 9-1-1. Police will be notified and will contact the appropriate Project Lifesaver Chapter to respond. When the specially trained volunteers are requested by their local police agency to respond, they use a mobile directional radio frequency receiver to tune into the client’s pre-programmed frequency. Listening for the client’s unique tracking signal will lead responders to the client, whether the client is stationary or mobile.
It has been proven that these transmitters are able to track through obstacles, such as concrete walls and heavy forest and these water resistant transmitters can be tracked on the ground or in the air over several miles.
