Handheld GNSS Receiver
FJD Trion V4e Pro
Handheld Laser GNSS Receiver, made simpler.
Pole-Free, Worry-Free
Still stuck setting up poles, fighting awkward angles, and second-guessing your measurements? FJD Trion V4e Pro is built to remove the friction from everyday field work. It lets you point, measure, and move on with confidence, even in challenging conditions. No extra setup, no careful posture, no repeated checks.
What Sets It Apart
Just Point, V4e Pro Handles the Rest
No poles to carry, set up, or reposition. Capture accurate coordinates by simply pointing, even at angles up to 60°, with precision down to ±3.5 cm.
Hit the Target Every Time
Just turn on the laser and follow the green beam to your stakeout point. The system confirms the position the moment you hit the target.
Made for Difficult Access Areas
Capture hard-to-reach spots without stepping in. Point and measure from where you stand, without physical access to the target.
Visible Under Sunlight
The bright green laser remains clearly visible in sunlight, so you can aim quickly and confirm points with confidence.
Grab and Go
Light enough to carry all day, powerful enough to keep up. Weighing just 320 g, it powers through 12 hours of work, recharges in under 3 hours, and stands up to 1.2 m drops on site.
Precision Across Every Field
V4e helps bring reliable GNSS positioning to broader field workflows. Use it with FieldFusion to collect field data and manage boundaries.
Helps You Get It Right, Anywhere
