The ARM-LOC slides onto the victim’s forearm and the rescue responder or the victim pulls the yellow lanyard that deploys and locks the device into place, eliminating the need for the victim to grasp a rope. It can also help float the victim when the victim pulls the device close to his or her chest. It can be deployed in seconds and re-deployed over and over again. ARM-LOC is an easy to use, life saving device that will give police, fire and rescue responders an extra arm in saving people trapped by various water disasters. It can be used for floods, hurricanes and tsunamis as well as ice and rapid water rescues and snowmobile and boating accidents.
