I'm looking for a GPS for my loved one. I find it hard to believe the devices I find on email often require someone to punch a panic button. Not sure that a person with Alzheimer's has that ability. Medic alerts also require some type of ability to call for help or a panic button. Not sure my loved one would remember to do that. Most devices are not always with the person, i.e. at night when they have retired for the evening. I researched and bought one, but it works hit and miss. Any suggestions?
