RE: Handheld GPS odometers
Here is a challenge/test for all out there that use a handheld GPS mounted
in their car.  And also for those with systems intended for use in vehicles.
Next time you are taking off to run errands around town, or going to work
and back, turn on the GPS, switch to the screen with the odometer display
and zero it out.  Let it run until you get back home.  Now record what the
total distance is.  Which units show near zero distance, which show actual
distance traveled?  Record results, report back to the list with make/model
data.
Thank You
