Questions we get about Emlid receivers
What comes free when I buy from 3D Mapping Tools?
A rubber protection bumper and a 1-year, 24 GB data-only SIM, with every RS4 and RS4 Pro. The RX2 runs on your phone’s data over Bluetooth, so it needs neither. Ask at checkout and we will install and test the SIM in your base. Emlid also includes 1 year of RTK corrections.
Do I need a base, or can I use an RTK network?
For the best accuracy, we recommend your own base on site. A base also keeps working where there is no cell coverage, because it talks to the rover over the built-in LoRa radio.
Many users run a single rover on an RTK network instead: your state's network (it varies by state), Point One Navigation (we offer this), Emlid RTK corrections (1 year free with every receiver), and others. Corrections come over the internet, either from your phone or tablet's data or from a SIM card in the receiver. Every RS4 and RS4 Pro from us includes a free 1-year, 24 GB data SIM for exactly this.
Can the RS4 be my base and my rover?
Yes, it works as either. Many crews pair an RS4 base with an RS4 Pro rover. On a tighter budget, an RS3 base with an RS4 or RS4 Pro rover is a solid setup too.
Which field software works with it?
Emlid Flow and MicroSurvey FieldGenius. Emlid Flow Pro covers the survey features most users need. FieldGenius is a full survey app: COGO, curves, offsets, surface staking and total station support, plus much more. It is sold as an annual or a perpetual license.
Do you offer financing?
Yes, through Approve and BNC Finance. Apply online in a few minutes, or use the Finance button above to apply for this item.
Can you help me get it working?
Yes. Every Emlid receiver we ship is updated to the latest firmware and ready for the field. On request, we will install and test your SIM in the base before it ships.
Our YouTube channel has setup videos, with more coming that cover every feature of Emlid Flow Pro. And when you have a question, call us at (901) 444-0804.
