This model is simply Sokkia's best ever.It represents the state of the art in levelling technology,and comes in a compact,sturdy,and easier-to-use package.Extremely precise levelling has never been simpler!

Accuracy over 1km double-run levelling is a remarkable 0.8mm,and it can be improved to 0.5mm using the optional parallel plate micrometer.Horizontal line of sight stability is assured by four suspension wires and a magnetic-damping compensator.Operating Sokkia's B1C & B1 Engineer's Grade Levels are convenient thanks to features such as the two-speed focusing knob, distance-giving stadia lines, and the choice of horizontal circles on the B1C. This model offers the best of Sokkia’s technology in one rugged and complete instrument that is reliable and easy to set-up.

Accurate Levelling 

The level's reticle can be fitted with the optional parallel plate micrometer for precise mesurement in encrements of 0.1mm.The accuracy obtained over 1km double-run levelling is boosted from 0.8mm to a remarkable 0.5mm with the parallel plate micrometer.

Rapid,Easy Set-Up

Using a s pherical-head tripod,setting up the level is fast and easy enen on anlged,uneven surfuces.Set the level onto the tripod head,centre the circular bubble,and away you go.It also fits flat-head tripods.Aiming,operable by right or left hand.Simply turn the instrument,then use the fine motion to aim the level at the target precisely.A two-speed focussing knob switches between coarse and fine focussing for even faster operation.The optics are designed to be bright and easy to use.

Reliable Automatic Compensator

Four suspension wires and magnetic damping action ensure statbiliy enen under rapidly changing atmospheric conditions,vibration,and shock.Precise damping even copes with "hang-ups" ins  the compensator.

Stadia

The stadia wires on the reticle allow easy calculations of distance.Simply multiply the distance on the rod between the top and bottom stadia lines by 100.
