"The new B series automatic levels feature further enhanced reliability under all environmental conditions," said Ian Stilgoe, geomatics business unit manager. The water protection rate of the B series models has been increased from IPx4 to IPx6. "Tough and compact bodies are fully resistant to driving rain and splashing water from all directions. The advanced protection technology also prevents the telescope from fogging or condensing without using nitrogen gas."Stilgoe said, "The telescope provides a bright and sharp view that reduces operator's eye strain. Four super-high-tensile suspension wires and a magnetic damping system ensure accuracy and stability even when exposed to temperature changes, vibrations or shock. "The unsurpassed compensator technology is also demonstrated by the Sokkia SDL1X, the world's highest-precision digital level that employs the common basic mechanism."
