Software to drive your entire workflow

The Reach RS4 Pro is powered by Emlid Flow—a complete field and cloud solution for iOS and Android. From initial setup to final verification, Emlid Flow keeps your entire team connected, your data synchronized, and your project on track.

Stake out faster with AR guidance

With the RS4 Pro, stakeout becomes visual. Rather than simply following coordinates on a map, your designs are directly overlaid on the real world, clearly showing where to place stakes.

Cut & fill indicator
Quick point switch

Crews can work faster with AR guidance, even on complex construction sites and roadworks.

Measure from images

Even if you can't put the pole there, you can still measure it with your RS4 Pro. Use the cameras to measure building facades, areas behind fences, across busy roads and any other inaccessible points.

Save time setting up a total station and avoid hazardous areas.

Quick release mount

The custom-designed quick release mount ensures the receiver is locked firmly to your survey pole, eliminating backlash. Even the smallest wobble can affect tilt-based measurements at steeper angles. This mount solves the issue with a fast and rock-solid connection for reliable data accuracy.

Next-gen tilt compensation

The advanced tilt compensation stays accurate even at steep angles. For example, at a 30° tilt, the Reach RS4 Pro still delivers 18 mm precision.1 Initialization takes just a few quick movements and remains stable throughout the job—no manual recalibration needed.
