I bought an apple air tag gor my husband it could be used in the car but I placed it in his wallet as he staetyed the wandering stage. It worked great for him as he always had his wallet in his pants pocket. Also you may want to consider it may be nearing time for him to stop driving and discuss with Dr. 😊🌹

We have used the Mini Guardian for about 2 years and are pleased with their service. You can google personal GPS devices and research until you find one that fits your needs. Or you could ask the Senior Comittee on Ageing in your area what they think, to steer you away from scams. That's their job.

My daughter bought us a gps tracker that I can keep in his car. Download the app to our phones -- $19.99 a month but piece of mind
