It worked under rainy conditions under oak and beech canopy (worst test conditions I could find :-)) and my results are within a meter, although I sometimes had to wait a little for the unit to aquire the sbas signal. In optimal conditions we get typically less than 50 cm. I have no experience near tall structures/buildings, we are a forestry, but I suspect the reception of any gnss antenna without correction signal will be worse when the line of sight to the satellite providing the sbas is broken. You might need a system with a separate correction signal subscription. I had three units for testing: Stonex 500, failed for us because it isn't whitelisted for (nor working with) iOS which my company requires, a Trimble R1 and the arrow 100 and I found the Arrow 100 better than the Trimble with quite a margin, tested them alongside in the same wet conditions. These are all apparatus which need to be linked to a mobile device. For us that's a plus because my collegues already are familiar with using collector so after coupling the device they work as usual, only more precise. Where Stonex 500 and Trimble R1 are 'boxes' (one unit)  the arrow series comes with a separate/external cabled antenna, slightly less comforable, the external antenna is mandatory. The antenna sits in a pocket on top of a baseball cap so the highest point and you keep your hands free, the unit itself sits in a pouch on your belt. There seems to be a pole-on-a-vest solution so you can get more height, the cap is good enough for me. I was able to test the unit(s) before I made the decision which one to buy, you may be able to do the same. Regards, bert  ... View more

Hello Victoria, Thanks for your reaction. The ground surface color is set to transparent. I have the dem's in my ground surface unlike your screenshot, I try to use them as better (more detailed) surface data than the world elevation3d surface And the Solution: I had switched off WorldElevation3D/Terrain3D which is necessary... Formulating this answer got me to find this, thanks for your time! Regards,  Bert ... View more

I've been using the EOS Arrow100 gnss receiver and I'm happy with the results. Good submeter accuracy which is enough for us (no subscription costs). Else I would have bought the Arrow 200 or Gold. You might check them out, works like a charm on Collector on iOS and Android. Be sure to look at the ESRI whitelist: https://doc.arcgis.com/en/collector/ipad/help/high-accuracy-prep.htm#ESRI_SECTION2_612D328A655644DCAF5CF0210308C821 Bert ... View more

Hi, Did you solve your problem yet? I seem to be able to use different symbologies in agol using the same feature layer without any problem. having one subtype and six domains I was able to make a webmap with several copies of the same feature layer with the symbology adapted for the different domains. regards, Bert  ...

Thanks all for three great answers from all over the globe! Bert ... View more

We use iphones and ipads and they work great, no 'classic' only collector. Should you consider using an external gnss antenna because of better accuracy than your average phone perhaps read this: Prepare for high-accuracy data collection—Collector for ArcGIS | Documentation  because not all gnss antenna's are cerfified with all smartphones so when you choose android (or ios) today you may limit your choices tomorrow.

Support told me the default value for the datefield (12/30/1899) is exactly what triggers the bug (their words). It should be fixed by now, in the end I worked around by using arcmap 10.6 which works fine with my dataset. ... View more
