Description

Discover the new way to survey with dual cameras

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.

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.

Unmatched precision, even under canopies and in canyons

The Reach RS4 Pro delivers centimetre-level accuracy, even in challenging environments like forests or urban canyons. With support for every GNSS constellation and signal frequency, including the L5 and L6 bands, resistant to multipath and interference, the Reach RS4 Pro locks onto 40+ satellites simultaneously using 672 channels.

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. Initialisation takes just a few movements and remains stable throughout the job—no manual recalibration needed.

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.

Base and rover connectivity

Connect to VRS or single-base CORS networks using RTCM3 format for precise RTK corrections. You can also transmit corrections from your own base using Emlid NTRIP Caster
