I can see the location of my watch on my phone. I am probably in the building. How close does the GPS get and how long will it work. If the battery is dead with this still work
Commercial GPS is generally good to about 10 meters (30'ish feet). But buildings and other metal obstructions can cause some signal deviations that may affect the 10 meter accuracy.
And if the battery is dead it can't transmit a signal,so it won't be able to report it's last position.
How close does the GPS work. I can see the location on my phone and cane find the watch
