This was given to me by my parents, and they get an update (geographic coordinates) of my progress on a hike, run, bike ride, or whatever activity I am doing.
It has a feature that can notify search and rescue that you need lifeflight.
The downsides to this is that you don’t get updates yourself. There is no screen so you can’t see if you are taking the same trail back.
If you are looking to have an extra safety net increase some of goes wrong get this product, however, if you are searching for a step by step tracking device I might look into something else.
