Reach RS3 Survey Kit
Two Reach RS3 receivers to use as base and rover
Professional surveyor kit with dual Reach RS3 receivers for RTK and PPK surveying. Advanced tilt compensation lets you survey accurately without leveling the pole—ideal for tight corners and challenging terrain. The survey kit delivers centimeter precision with 18-hour battery life. The essential professional surveying tool for demanding field work. Comes with a mobile app.
IMU tilt compensation

Calibration-free and immune to magnetic disturbances
Emlid Corrections
To achieve centimeter-level (sub-inch) accuracy with RTK, you need a source of corrections — positioning enhancement data that upgrades standard GNSS accuracy from meters to centimeters in real time.
Your receiver includes one free year of Emlid Corrections — a built-in network service to receive corrections over the internet. Learn more and check coverage in your area.
