GPS devices produce very accurate results down to a few meters. A Satellite Based Augmentation System (SBAS) can increase accuracy by a meter or two. The Wide Area Augmentation System (WAAS) is one SBAS in use in North America. Retrevo Labs has selected only WAAS enabled GPS for this list.

Retrevo has applied their AI-based gear and gadget feature analysis tool that looks at GPS reviews, GPS user reviews, and important GPS features to select top rated GPS devices you can use in your car or on the trail. Retrevo's automated and objective product analysis algorithms that use multivariate Bayesian decision theory and supervised machine learning determined various product facts deemed important in the marketplace, along with user opinions, to identify this list of top GPS products.
GPS for Accuracy and Portability
Andrew Eisner, director of content, comments, "GPS devices produce very accurate results down to a few meters. A Satellite Based Augmentation System (SBAS) can increase accuracy by a meter or two. The Wide Area Augmentation System (WAAS) is one SBAS in use in North America. Retrevo Labs has selected only WAAS enabled GPS for this list."
Eisner added, "If it looks like Garmin dominates the list, it does. In our opinion, Garmin is the market leader in most GPS categories that includes companies like Tom-Tom and Magellan GPS. Despite commanding a price premium they have the important features and high ratings from experts and in user reviews."
