What is the difference of V4e and V4e Pro?
The main difference between the V4e and the V4e Pro lies in how they are used in the field.
- V4e is designed for pole-mounted use, making it ideal for standard RTK surveying tasks such as stakeout and as-built checks.
- V4e Pro is designed for handheld operation and features tilt compensation and a built-in laser rangefinder, allowing users to measure hard-to-reach or obstructed points without leveling the pole.
Both models offer RTK-level accuracy, but the V4e Pro provides greater flexibility and efficiency in complex environments.
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 RTK 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 RTK 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 RTK GNSS positioning, tilt compensation, and a laser rangefinder.
- RTK 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
