Many field professionals are yet to discover the full capabilities of this GNSS device. Yes, it is more than a handheld GPS, because it can track other satellites. The Ruinone RDC 20 may not be the most requested GNSS device. Still, based on its rugged construction, long battery life, stable multi-constellation tracking, and affordability, it should be one of the top options for anyone working in surveying, GIS, agriculture, forestry, environmental studies, and field mapping.
This is not just a handheld GPS; it is a full GNSS receiver capable of receiving signals from multiple satellite constellations (BDS, GPS, GLONASS, Galileo, and QZSS) and using differential corrections (SBAS) for accurate field positioning.
