•Intelligent dual batteries
Support up to 10 hours of work time, battery power can be read directly from the indicator light on the battery, the battery models of handheld device and host are same.
•Web UI
Access the Web page, complete the receiver configuration, download data, upgrade firmware, view status, etc. through the mobile phone, tablet and other handheld devices.
•Tilt survey
The SR3 receiver integrates an electronic bubble sensor, combined with a new tilt survey algorithm and surpad software operation. No calibration is required before measurement, the accuracy of coordinate data can be easily achieved within 30° tilt angle.
