The device is quite amazing. Will use 30-40 satellites from a mix of GPS, GLONASS, BEIDOU, QZSS (only on Windows, not on Android) and GALILEO. Is getting signals from both L1 (1575MHz) and L5 (1176MHz) bands from most GALILEO and half of BEIDOU and GPS, so removes most of the ionosphere noise. And then the kicker is, if I capture the raw measurements I can then run it against corrections from Geoscience Australia and get 10-30cm accuracy, so they say.
In a session this afternoon I walk around objects of interest and form a star on survey marks. I also walked around a sporting pitch circle to apply the circle test, that is travel in a circle and then the largest inner and smallest outer circle that encompasses all points indicates the accuracy. Looking about 17.5m inner and 19m outer for a soccer centre circle. So I’m convinced.

I'd suggest fairly good for road centering in open places (ie no phase delay GPS reflections). No good for non
