Choose RS4 when tilt compensation will save significant time or when L5 frequency support improves your environment.
Choose EMLID Reach RS3 if...
Choose RS3 for standard surveying where tilt compensation isnt critical and budget is a consideration.
Frequently Asked Questions
What is tilt compensation?
Tilt compensation allows accurate measurements without perfectly leveling the pole, saving time and reducing errors in the field.
Do I need L5 frequency support?
L5 provides better multipath rejection and faster fixes in challenging environments. Standard open-sky surveying works fine with L1/L2.
How much time does tilt compensation save?
Professional surveyors report 20-30% time savings from not having to level the pole for each point.
Are both compatible with drone workflows?
Yes, both integrate well with drone mapping workflows for GCP collection and RTK base station use.
What about RS2+?
The RS2+ is EMILDs entry-level option—capable for basic work but lacks the features of RS3/RS4.
Which does THE FUTURE 3D use?
We use RS4 for professional surveying and GCP collection, leveraging tilt compensation for efficiency.
