Reach RS4 Pro

Reach RS4 Pro combines centimetre-level RTK with a dual-camera system for AR stakeout and image-based measurement—so you can capture points you can’t stand on and work faster in complex environments. With all-band, multi-constellation GNSS (L1/L2/L5/L6), fast IMU tilt, and rugged engineering, RS4 Pro is built for real sites and real deadlines.

Key benefits

• Vision workflows: AR stakeout guidance and measurements from photos for hard-to-reach points.

• All-band RTK accuracy: robust fixes in canopy, urban, and mixed-sky conditions.

• Fast IMU tilt: quick initialisation for reliable, level-free shots.

• Rugged & connected: IP68 magnesium body with LTE, dual-band Wi-Fi, Bluetooth, and multi-band radio.

• Seamless software: works with Emlid Flow / Flow 360 for coding, stakeout, sync, and export.

Ideal applications

Topographic & engineering survey • Construction set-out • Utilities & asset capture • Rail & highways control • As-built verification • Sites with restricted access
