DSZ3 comes in a compact,sturdy, and easier to use carrying case. Horizontal line of slight stability is assured by four suspension wires
    and magnetic damping compensator. Accuracy over 1km double leveling is ±mm, but for models DSZ3-30A,DSZ3-32A it can be
    improved to ±mm combined with the optional parallel plate micrometer.

Excellent structure is sturdy,compact, and more tightly sealed against humidity and dust for superior performance whatever the
    conditions. It is quick and easy to set up, simple to sight, and immune to vibration, shock, and other environment conditions.

Four suspension wires and magnetic damping action ensure stability, even under rapidly changing atmospheric conditions, vibration ,
     and shock. The reliable automatic compensator is high quality, with a large ±15

The levels comes with an easy-to-use horizontal circle for measuring angles(direct to 1±or 1gon). The readout window is conveniently
     located on the instrument base-directly below the eyepiece.

The level incorporates an endless horizontal motion drive with two knobs for fast and easy aiming, operable with the right or left hand.
    simply turn the instrument, then use the fine motion to precisely aim the level at the target.

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