A note on Cellphones
and GPS units. Cell phones
could be helpful in some cases to summon assistance. But keep in mind that
cell phone coverage is not universal and that a 911 call from a cell phone
does not supply the dispatcher with your location. That is information you
must provide. GPS units can be very helpful in giving a location, but keep
in mind the accuracy varies depending on the unit you are using. You will
still need to provide a reference related to a map landmark. It is still up
to you to know your approximate location.
