Emlid Reach RS4 Pro
Next-generation multi-band RTK GNSS with vision-powered workflows. The Reach RS4 Pro delivers centimetre-level accuracy and introduces AR stakeout and image-based measurement to speed up work on real sites - especially for points that are obstructed or hard to access.
Why RS4 Pro
-
Vision toolkit: Dual cameras enable AR stakeout and image-based measurements so you can capture where you can’t stand.

-
Fast tilt compensation: Next-gen IMU with 5× quicker initialisation keeps you moving between shots.
