●Large digital display that is easy for anyone to read
The angle reading has been digitized using the latest electronic technology, including rotary encoders, microcomputers, and color LCDs, making it easy for anyone to read.

●Various functions provided by the microcomputer
Operation functions, self-error check functions, and more allow you to conduct surveys easily and with peace of mind.

●Easy zero setting
The display will reset to 0 simply by pressing the zero-set switch.

●Convenient 90° division
When measuring horizontal angles, a buzzer sounds and the display mark flashes every 90°, allowing you to quickly divide the angle into 90° increments.

●Bidirectional reading
By pressing the left/right switch, you can read both clockwise and counterclockwise horizontal angles.

●Power-off prevention function
An energy-saving mechanism that turns off the power if left idle for 10 minutes.

●Built-in illumination
The built-in illumination mechanism illuminates the display and telescope crosshairs for 30 seconds.

Uses easily available AA batteries.

●Sealed telescope structure
The sealed structure filled with nitrogen gas prevents the inside of the telescope from fogging up, even on rainy days, allowing you to use it with peace of mind.

●Water-resistant body
The switch panel, display, and covers are sealed with rubber gaskets.

●Single-axis vertical axis
A single-axis vertical axis is adopted to improve mechanical accuracy and reduce the risk of incorrect operation.

●Fixed-moving coaxial design
The vertical axis and horizontal axis are fixed and moved co-axially.
It can be operated with a single touch.
