Call off the search party. Here is a device that can find those who are lost immediately. The Keruve GPS tracking device is a watch that can be worn by anyone, but was really designed for the purpose of aiding people with Alzheimer's. This High Tech watch has a built in GPS tracker and can be easily monitored via a small GPS receiver that the caregiver would carry with them. The receiver can also be set up to establish a perimeter that a patient can roam within and alert the health care worker when he/she has gone beyond a boundary.
Unlike regular watches, this watch has a wristband that has a locking mechanism that can only be opened with the use of a special tool (hopefully the tool doesn't get lost). The Keruve tracking device is also waterproof.
I know an invention such as this provides peace of mind to those in the caring field and safety for those who suffer from memory loss, but I also think this would be great for parents who want to know their child's whereabouts. What do you think?
