FJD Trion V4e Pro – Pocket-Sized Laser GNSS RTK Receiver, 320 g
The FJD Trion V4e Pro is a handheld laser GNSS receiver that removes the friction from everyday field work. No poles to carry, set up or reposition: point, measure and move on with confidence, even in challenging conditions.Capture coordinates by simply pointing, even at angles up to 60°, with precision down to ±3.5 cm. For stakeout, turn on the bright green laser and follow the beam to your point; the system confirms the position the moment you hit the target. Hard-to-reach spots can be measured from where you stand, and the laser stays clearly visible in sunlight.V4e Pro tracks all global constellations with 1408 channels and delivers RTK accuracy of H ≤ 0.8 cm + 1 ppm and V ≤ 1.5 cm + 1 ppm. A built-in IMU supports tilt surveying up to 30°, and laser measurement accuracy is ≤ 3 cm at 3 m. Startup is fast: ≤ 30 s cold, ≤ 5 s hot and RTK initialization in under 5 s.At just 320 g, it runs for at least 12 hours, recharges in under 3 hours and withstands 1.2 m drops. Available as the Essential Kit, the Survey Kit with the FJD Trion Survey App, or the Field-Pro Kit with the FJD E600 controller. Benefits Measure without a pole: point and capture, even at angles up to 60°. Laser-guided stakeout that confirms the point the moment you hit it. 1408-channel RTK with H ≤ 0.8 cm + 1 ppm accuracy. 320 g, 12+ hours of battery life and 1.2 m drop resistance. Applications Topographic surveys Road surveys Construction stakeout Utility mapping Agricultural field mapping

Overview
The FJD Trion V4e Pro is a pocket-sized handheld laser GNSS receiver. It is intended for surveyors and field teams who want to measure and stake out points without carrying and leveling a pole.
Point, measure and move on: the green laser guides stakeout and confirms the point when you hit it, and hard-to-reach spots can be measured from where you stand.

FJD Trion V100F – GNSS and LiDAR Fusion Surveying System
The FJD Trion V100F combines GNSS surveying, 3D LiDAR scanning, cameras and IMU in one device. It supports continuous data capture in open, obstructed and GNSS-limited environments, helping surveyors capture points, lines, surfaces and volumes more efficiently on road, bridge, tunnel, mining and other complex engineering projects.SureFix keeps pole-based measurement going as you move from open sky into nearby GNSS-limited areas, with a typical accuracy of ±5 cm within a 20 m radius. For safer non-contact measurement, select targets from captured images for LiDAR-based coordinate measurement within 20 m (±5 cm typical), measuring trench edges, wall corners, areas beneath bridges and slope boundaries without approaching them.Scan tunnels, culverts and slopes for cross-sections and volumes in a single pass, and get stockpile and earthwork volume results directly in the field with FJD Trion Survey. Point clouds, measurements and analysis are then processed in FJD Trion Model. Benefits GNSS, LiDAR, cameras and IMU in one field instrument. Keep measuring in GNSS-limited areas with SureFix (±5 cm typical within 20 m). Measure hazardous or hard-to-reach points without contact. Get cross-sections and volumes on site with FJD Trion Survey.
