How accurate is the Sureshotgps™?

GPS accuracy is affected by a number of factors, including satellite positions, noise in the radio signal, atmospheric conditions, and natural barriers to the signal. Noise can create an error between 10 to 15 meters and results from static or interference from something near the receiver or something on the same frequency. The most accurate determination of position occurs when the satellite and receiver have a clear view of each other and no other objects interfere.
