i love my gps's...
the hard part is not looking at it while in motion. i want
to see how fast i am not going and which direction i should
have been headed....
i can see me running into a parked car or go through a red
light.....
it has a tracking feature that draws a line as you get lost, so
when you turn around and stay on the line you are sure to
be still lost. consistency is important in the woods.
it has a light, but you have to put your face verrrrry close to
the screen to read it. this function will help you find a parked
car quickly.
i am sure there are other useful features, too.
i have 2 of these units and i can compare degress of lost.
