V4e vs. V4e Pro Feature V4e V4e Pro GNSS Channels 1,408 1,408 RTK Accuracy Centimeter-level Centimeter-level IMU Tilt Compensation — ✓ Up to 60° Integrated Laser Measurement — ✓ Weight 320 g 320 g Battery Life Up to 12 hours Up to 12 hours Protection IP67 IP67 STANDARD VERSION FJD Trion V4e Mini RTK Receiver The V4e provides a compact and efficient RTK GNSS solution for professionals who need accurate positioning without carrying a larger surveying receiver. With 1,408 GNSS channels and centimeter-level RTK positioning, it is designed for everyday mapping, field data collection, and precision positioning tasks. Designed for Efficient RTK Mapping The lightweight 320 g receiver is easy to carry throughout the workday. Its compact design, IP67 protection, and up to 12-hour battery life make it suitable for field environments where portability and reliable positioning are important. 1,408-channel GNSS receiver Centimeter-level RTK positioning Compact 320 g design Up to 12 hours of battery life IP67-rated protection Suitable for mapping and field data collection PROFESSIONAL VERSION FJD Trion V4e Pro Mini RTK Receiver The V4e Pro builds on the V4e platform with integrated IMU tilt compensation and laser measurement. Instead of requiring the receiver to remain perfectly vertical over every point, the V4e Pro allows users to collect points at different angles, helping improve efficiency when surveying difficult or hard-to-reach locations. IMU Tilt Compensation Built-in IMU technology enables tilt-compensated surveying without requiring the receiver to remain perfectly upright. The V4e Pro supports measurement at angles of up to 60°, helping users collect points more efficiently in real-world field conditions. 30° 3D error ≤ 2.5 cm 60° 3D error ≤ 3.5 cm Integrated Laser Measurement The integrated green laser allows the V4e Pro to measure points without placing the receiver directly over the target. This pole-free workflow is especially useful for corners, edges, obstacles, and other points that may be difficult to access directly. 60 m Maximum laser measuring range ±3 mm Laser ranging accuracy Green Class 2M laser V4e PRO Pole-Free Surveying for Hard-to-Reach Points Combining RTK positioning, IMU tilt compensation, and integrated laser measurement, the V4e Pro provides a more flexible way to collect points where traditional pole-based measurement can be inconvenient. Point & Measure Aim toward the target point and collect measurement data without positioning the receiver directly over the point. Measure at an Angle Tilt compensation helps maintain efficient data collection when the receiver cannot be held perfectly vertical. Reach Difficult Points Laser measurement helps capture points around obstacles, edges, and other difficult-to-access locations.
