Visibility as a rescuer on the scene is paramount in low light and low visibility situations. Cascade Rescue is pleased to offer one of the most innovative devices for this purpose available today. The Guardian Angel easily mounts to your shoulder via an exceptionally strong magnetic contact device. It can be quickly detached and adhered to any metal surface at the rescue scene alerting anyone in the vicinity that rescue operations are in process and to steer clear of the emergency scene.
