Is GPS Handheld Receiver 100% accurate?
That would be nice, but it is unrealistic to expect that a GPS Handheld Receiver can be totally accurate, given all the things that can cause errors in the data. A few of these causes are: a delay in data from the layers in the atmosphere, tall buildngs or mountains that the signal can bump against, errors in the clock in the GPS, inaccuracies in the reported location of the satellite, and not having enough satellites “visible”. Some things that can interfere with your handheld pocket GPS receiver. The clearer the view of the sky, the better it will work.
