EFIX F8L Laser IMU-RTK GNSS Receiver

The EFIX F8L is a professional laser GNSS IMU-RTK receiver designed for high-precision surveying, construction layout, engineering, mapping and stakeout work. It combines GNSS positioning, RTK accuracy, laser measurement, 4D Auto-IMU tilt compensation and AR vision tools in one field receiver.

The EFIX F8L is designed for land surveyors, construction professionals, civil engineers, infrastructure contractors, road survey teams, mapping specialists and GIS users who need fast, accurate field measurements in a wide range of site conditions.

The EFIX F8L adds laser surveying, AR vision stakeout and 4D Auto-IMU technology to a high-performance RTK GNSS receiver. This helps users measure points that are difficult, unsafe or impossible to reach directly with a survey pole.

Yes. The EFIX F8L is suitable for construction layout, stakeout, road work, earthworks and engineering projects. When used with eField software, it can support CAD-based workflows, visual stakeout guidance and road-related field tasks.

Yes. The EFIX F8L is built for professional land surveying tasks including point collection, boundary work, topographic surveys, stakeout, mapping and high-precision RTK measurements.

The EFIX F8L supports multiple GNSS constellations, including GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC/IRNSS and SBAS. This multi-constellation support helps improve satellite availability and positioning reliability in the field.

The EFIX F8L has 1608 GNSS channels, allowing it to track multiple satellite signals across supported constellations and frequencies.

Under suitable open-sky conditions, the EFIX F8L can achieve RTK accuracy of 8 mm + 1 ppm horizontal and 15 mm + 1 ppm vertical. Actual accuracy depends on satellite geometry, correction quality, multipath, atmospheric conditions and field environment.

The EFIX F8L has a typical RTK initialization time of less than 10 seconds under suitable conditions, helping surveyors start measuring quickly after setup.

4D Auto-IMU is the receiver’s inertial tilt compensation system. It allows users to measure with the pole tilted instead of keeping it perfectly vertical, helping speed up work around obstacles, walls, slopes and busy job sites.

The EFIX F8L uses a calibration-free IMU designed for pole-tilt compensation. It can initialize automatically while moving and is designed to be resistant to magnetic disturbance.

The EFIX F8L supports IMU tilt measurement from 0 to 60 degrees, allowing efficient tilted-pole measurement in many surveying and construction situations.

Laser surveying lets the EFIX F8L measure points by aiming its integrated green laser at a target. This is useful for capturing hard-to-reach, hazardous, obstructed or signal-challenged points without placing the pole directly on the point.

The EFIX F8L laser has a range of up to 50 m. Laser measurement performance can vary depending on target surface, lighting, distance, angle and site conditions.

The EFIX F8L uses a Class 3R green laser. Operators should avoid direct eye contact with the beam and follow the laser safety instructions in the product documentation.

AR Vision Stakeout uses the field view on the controller screen to guide users to stakeout points with visual overlays, arrows and distance information. This makes point location more intuitive than relying only on a map or numeric offsets.

Yes. When paired with eField software, the EFIX F8L can support CAD-based field workflows, including large-scale CAD handling, dynamic map orientation and graphical stakeout support.

Yes. The EFIX F8L can be used for road and infrastructure stakeout workflows. With eField software, it can support LandXML cut-and-fill visualization to help users interpret road design data more easily in the field.

The EFIX F8L is commonly used with EFIX eField software, an Android field data collection application for GNSS surveying, RTK work, stakeout, mapping, GIS collection, road measurement, road design and construction layout workflows.

Yes. The EFIX F8L includes an internal UHF radio with a 410–470 MHz frequency range. UHF radio use may be subject to local regulations, so users should check permitted frequencies and power settings in their region.

The EFIX F8L does not include an internal internet modem. It can still be used with compatible field workflows and correction sources through supported communication methods and controller-based connectivity.

Yes. The EFIX F8L supports NTRIP Client and NTRIP Caster functions, making it suitable for RTK correction workflows where network corrections are available.

The internal battery can provide up to 20 hours in RTK rover UHF mode without camera, up to 15 hours in laser survey mode, up to 15 hours in vision stakeout mode and up to 12 hours when used as a UHF RTK base. Battery life depends on settings, operating mode and temperature.

Yes. The EFIX F8L is IP68-rated for waterproof and dustproof protection and is designed for demanding field environments.

The EFIX F8L is designed for field use with IK08 shock resistance, 2 m pole-drop survival, IP68 protection and an operating temperature range from -40°C to +65°C.

The EFIX F8L supports common surveying and GNSS data formats including RTCM, CMR, RINEX, NMEA 0183 and EFIX static formats, helping it fit into professional field and office workflows.
