Emlid Reach RS4 Pro
The Reach RS4 Pro builds on the RS4 platform by adding dual Full HD cameras for AR stakeout and remote point measurement, plus a free first year of Emlid Corrections included as standard. Stake out points visually with your design overlaid on the real world, or measure a point you can't physically reach, across water, behind a fence, over traffic, without setting up a total station.
Why the RS4 Pro Over the Standard RS4
- Stake out visually with AR guidance, seeing your design overlaid on the real world through the camera rather than following coordinates on a screen.
- Measure points you can't physically reach, across water, behind fences, over traffic, above pits, or around machinery, using the dual cameras instead of a total station.
- Get a free year of Emlid Corrections included, VRS-based RTK accuracy of 1-2cm with zero base station or NTRIP setup required, just open Emlid Flow and tap to connect.
- Work with zero recalibration, thanks to the same next-generation tilt compensation as the RS4, holding 18mm precision even at a 30° tilt.
Stake Out Faster With AR Guidance
Rather than watching a coordinate counter tick toward zero, the RS4 Pro overlays your design directly onto the camera view, with dynamic navigation, an auto bullseye view as you approach the point, a cut-and-fill indicator, and quick point switching between targets. This turns stakeout into something visual a crew can follow at a glance, even on complex sites with multiple points to hit in sequence.
Measure From Images
Use the dual cameras to measure building facades, points behind fences, across busy roads, or anywhere a survey pole genuinely can't go safely. This replaces the need to set up a total station for those specific points, keeping crews out of hazardous areas rather than risking a measurement in traffic or near machinery.
High Accuracy, Even Under Canopy
The RS4 Pro tracks every major GNSS constellation and frequency, including the interference-resistant L5 and L6 bands, locking onto 40+ satellites simultaneously across 672 channels. RTK accuracy reaches 7mm+1ppm horizontal and 14mm+1ppm vertical, with a typical fix achieved in under 5 seconds.
Your First Year of RTK Corrections Is Included
Emlid Corrections comes built into the receiver, VRS-based RTK with 1-2cm accuracy and zero configuration, no base station and no NTRIP setup required. After the first year, continued coverage runs at $699/year, or lock in three years for $1,199 total, backed by a full refund if you're not satisfied.
Flexible Base and Rover Connectivity
- Run NTRIP RTK with VRS or single-baseline CORS networks in RTCM3 format, or broadcast your own corrections via Emlid NTRIP Caster.
- Use the included UHF antenna (410-470MHz, up to 2W, TRIMTALK 450S compatible) for direct base-to-rover transmission.
- Use the included LoRa antenna (860-930MHz, up to 1W, up to 8km range) for Reach-to-Reach communication without licensing hurdles in most regions.
Next-Generation IMU Tilt Compensation
Precise measurements without keeping the pole perfectly vertical, holding 18mm precision even at a 30° tilt. The compensation activates within a few movements and stays stable throughout a survey without frequent recalibration, useful for kerbs, boundaries, walls, and other hard-to-reach points.
Precision Quick-Release Mount
A purpose-built quick-release mount eliminates backlash and movement between the receiver and pole, giving a secure, repeatable fit while still allowing fast attachment and removal in the field.
Built for Harsh Environments
- Carry a lightweight magnesium alloy chassis, the same material class used in aerospace and high-end electronics.
- Run up to 16 hours on a single charge via USB-C, or extend a session from a power bank.
- Work through dust, rain, snow, and construction sites with a fully sealed IP68 rating.
- Operate from -40°C to +65°C, holding performance across the full range of UK conditions.
Emlid Flow: Field to Cloud
The RS4 Pro runs on Emlid Flow across iOS and Android, covering topographic surveys, stakeout and layout, line and road surveys, cut and fill calculations, and as-built verification against design plans. Teams can invite members, sync data in real time between field and office, and work from one consistent interface without extra training.

Frequently Asked Questions
What's the difference between the RS4 and the RS4 Pro?
The Pro adds dual Full HD cameras for AR stakeout and remote point measurement, plus a free first year of Emlid Corrections included as standard. Core GNSS performance, tilt compensation, and build quality are otherwise identical between the two.
Do I still need the RTK Network Subscription if Emlid Corrections is included?
Worth checking with our team before ordering, since the RS4 Pro already includes a year of Emlid's own RTK correction service. Whether our standard RTK Network Subscription inclusion adds genuine extra value on top, or overlaps with what's already bundled, depends on your specific workflow and coverage area.
Can the RS4 Pro be used for PPK as well as RTK?
Yes, RINEX data logging is supported for PPK workflows alongside live RTK correction.
Does the AR stakeout feature need a strong data connection?
No, AR stakeout runs on the receiver's own GNSS position and camera feed locally, it doesn't depend on live internet or cellular signal to function.
What warranty comes with the RS4 Pro?
Emlid provides a 2-year manufacturer warranty on the Emlid Reach RS4 Pro
Can I get this on finance?
Ltd companies can access iwocaPay financing, and individual buyers can use Klarna or Clearpay at checkout.
Why Buy From Drone Safe Store
Every Emlid RS4 Pro ships from UK stock, and our team can talk through whether the Pro's dual-camera features genuinely suit your workflow, or whether the standard RS4 covers what you need at a lower price.
