RTK Smart Antenna for Surveying

I just purchased a RTK Smart Antenna from Ardusimple, to help us during drainage maintenance in finding the pipes more easily.
I didn’t took the pre-assembled and pre-configured option (saving a few bucks, and have nothing else to do), and the seller warned me that no documentation was available for the moment to help us assemble the antenna, main board, RTK receiver, battery, and the case.
So I was just wondering, do anybody already tried to do such a thing ? Or do you have any recommandation regarding this equipment ?

This RTK Smart antenna?

Yes, exactly !

I also was looking at that RTK Smart Antenna and was thinking it would be handy to help quickly check levels of fields for drainage also for mapping drains. But unsure if it would do the job or not.

i think with constant RTK fix to the cm accuracy level, it will do the work to mapping the drains with accurate coordinates on maps, also with height

Actually, RTK Smart Antenna - ArduSimple is supplied preassembled and preconfigured as a rover.
