How to use the V4e P?
A user manual is included with the product. You can also refer to the video.
Using the V4e Pro is simple and efficient:
- Power on the device and connect it to a compatible controller or mobile device
- Initialize GNSS positioning using your preferred correction source
- Aim the built-in laser at the target point
- Measure points directly without the need to level the pole
- View and record data in real time using supported software
The handheld design and tilt compensation make the V4e Pro especially easy to use in confined or hard-to-access areas.
What is the warranty of the V4e P?
The V4e P comes with a 12-month warranty from the date of purchase. You can use it with confidence knowing that we stand behind the quality of our product. If any issues arise, please feel free to contact our support team for assistance.
Can V4e P be used indoors and outdoors?
The V4e Pro is primarily designed for outdoor use, where GNSS positioning provides high-precision results.
In environments where GNSS signals are available, it performs reliably in construction sites, infrastructure projects, and field surveys.
Indoor use may be limited due to GNSS signal availability.
How does the V4e P work?
The V4e Pro works by combining GNSS positioning, tilt compensation, and a laser rangefinder.
- GNSS provides centimeter-level positioning accuracy
- The tilt sensor compensates for pole inclination
- The laser rangefinder enables accurate point measurement without direct contact
Together, these technologies allow fast, accurate measurements even when targets are difficult to reach.
What can you do with the V4e P?
LiDAR scanners can be used for a wide range of applications, including:
- 3D mapping and surveying
- Construction and infrastructure inspection
- Agriculture and forestry measurement
- Terrain and land analysis
- Robotics and autonomous navigation
- Building information modeling (BIM)
- Asset documentation and digital twins
What is the difference between the free FJD Dynamics app and the Trion Survey app?
The FJD Dynamics app is a free, entry-level tool for basic mapping and small-scale agriculture (supports iOS/Android). The Trion Survey app is a professional-grade software for surveying and engineering, featuring AR stakeout, CAD overlays, and 60° IMU tilt compensation (supports Android only).
What data formats does Survey support for export?
Trion Survey: Supports comprehensive industry-standard CAD/GIS formats, including .dxf, .shp, .kml, .dat, and .rw5.
Hello, I am very interested in your products, but I am a poor person and at this moment it is difficult for me to pay the full amount of $1399. I would like to purchase it in installments if possible. Could you please help me with this option?
Small enough to fit in a backpack, yet delivers professional-grade positioning. The RTK init time is fast, and I didn’t expect this level of reliability in such a portable device.
The advertised 12+ hours of continuous use is real. I charged it in the morning and still had juice after a long day of surveying. Very dependable.
This RTK receiver is great for someone transitioning from consumer GPS tools to professional surveying. The setup was straightforward and the connectivity with NTRIP corrections works flawlessly. It definitely sped up my workflow.
I’ve been using the Trion V4e for a few weeks now, mainly for site stakeouts and quick topographic checks. The centimeter-level accuracy it achieves in a receiver this compact is honestly impressive. Battery life easily lasts a full workday, and the IP67 rating gives me confidence in rough conditions.
Bought this for precision agriculture tasks and it’s exceeded expectations. Lightweight enough to carry all day, yet strong enough for accurate field mapping. Performance and price ratio are excellent.
I love the portability, but wish the button layout was slightly more intuitive. Still, once I got used to it, the accuracy and battery life made up for the learning curve.
Upgraded to the Pro for the tilt compensation and laser rangefinder — huge difference when working in trees or uneven terrain. Makes point capture much faster without worrying about pole leveling.
Performance is solid, and it links to my controller and NTRIP service easily. My only gripe is that the manual could be more detailed — took some trial and error to get advanced settings right.
