It's not in the LEAST bit accurate. Like ±200m or so. This is hopeless  
if you want to measure the rise & fall of the tide, atmospheric  
pressure for weather purposes or for sports aviation. I don't know if  
climbers & walkers ever use altimeters, but in distinguishing of  
height, GPS would be poor for that too.
