I have eagerly wished to buy this product since its first release in 2019, but I have been reluctant, because it seemed too good to be true. However, during the last two years accumulating evidence suggests that this GNSS receiver compares well in terms of accuracy, speed and stability with other much more expensive devices. I received this product just yesterday, so I have not been able to thoroughly test it. Nevertheless, everything looks as it purports to be. It is well built, it can track a significant number of satelites in several navigation systems (GPS, GLONASS, Galileo etc.), its battery charges quickly. The free of charge Reach View App, is simple and functional, now supporting the Hellenic Geodetic Refernce System (GGRS87) along with many others. It is also constantly incorporating new features. I look forward to testing and using my Reach RS2 receiver for my archaeological surveys and excavations.
