If u decide to add another Emlid, get a RS3 with TILT as a ROVER for that extra convenience on projects u may need it for. For critical projects turn OFF tilt for maximum accuracy. Use the RS2 as a BASE via LoRa for maximum accuracy also. You also have the option to receive UHF radio to the RS3 when that need arises via high powered UHF radio “added” to BASE or from some other UHF capable base.
