Sokkia’s B series automatic levels feature enhanced reliability under all environmental conditions. Their rugged, compact bodies are tightly sealed against water, dust and humidity (IPx6). Quick setup, easy sighting and superior durability against vibration and shock ensure increased productivity.

The B series levels incorporate field-proven precise and reliable compensators for accuracy you can rely upon.
