Quick release mount

This mount is specifically designed for tilt compensation, eliminating backlash and securing the receiver firmly to the survey pole. Even a small amount of wobble between the device and the pole can compromise the accuracy when tilting. The quick-release system provides a fast and reliable connection for maximum precision.

Next-gen tilt compensation

The Reach RS4 delivers accurate results even at high tilt angles — for example, a 30° tilt still achieves 18 mm precision.1 The compensation mechanism activates with just a few moves and remains stable throughout the survey, saving time and avoiding the need for recalibration.
