PENTAX GX2 Series

Each of the three GX models is equipped with new features to support GNSS surveying works.
GNSS surveying is evolving to become more efficient and innovative.

AR stakeout support

All three models of the GX are equipped with cameras for AR stakeout. The cameras capture the ground beneath the receiver and display the footage in real-time on the data collector’s screen. The screen shows the direction and distance to the stakeout points, visually guiding the surveyor.
