The eSurvey E300 Pro is a fully functional GNSS receiver with an extremely compact design by eSurvey GNSS. With its high-performance GNSS board, it can track all present constellations and satellites. The GNSS, Wi-Fi, Bluetooth, and GSM four-in-one antenna, stable data transmission, RTK assistant, and IMU function, make it suitable for all surveying applications.

Selling point 1

Power Indicator: An Intelligent Hint of Working Time

Quickly check the remaining battery power in real time and figure out the working time without data loss.

Selling point 2

RTK Assistant Technology: Uninterrupted Work

Work without interruption even when RTK corrections fail, powered by our RTK assistant technology.

Selling point 3

Max 60° Tilt Survey: A Different Way of Working

  • Quickly measure accurate points while standing or walking without leveling the pole.
  • Concentrate on where the pole tip needs to go, which is especially useful during a stakeout.
  • Easily start a survey in environments that are hard to reach, such as building corners and slopes.
  • No longer worry about the movement of the pole when measuring, provided that the pole tip is stationary.
