key Features:
1.Excellent performance under any condition
Get outstanding precision for all your leveling tasks. The B20 levels incorporate the most accurate and reliable compensator available in the market today.
Tough, compact bodies sealed against water, humidity, and dust.
Quick setup, easy sighting and superior durability against shock and vibration.
Exceptionally bright and sharp view.
2.Precise reliable automatic compensator
Four super-high-tensile suspension wires and a magnetic damping system ensure accuracy and stability even when exposed to temperature changes, vibrations, or shock.
3. Advanced telescope
The outstanding design of the telescope provides an exceptionally bright and sharp view that reduces operator's eye strain. Ultra-short focus distance of 20 cm from end of telescope makes it easy to use in confined locations.

4. Stadia
Stadia lines on the reticle allow distance measurements. Simply multiply the staff length between the top and bottom stadia lines by 100.
5. Quick collimation
Endless horizontal motion drives can be operated with either hand for fast and easy aiming of layout and alignment tasks.
6. Horizontal angle measurement
Horizontal angles can be read in 1` or 1 gon units. Freely rotatable circle allows any angle reading from zero. Right angles can be quickly set for layout and alignment tasks. The readout window is conveniently located on the instrument base directly below the eyepiece.
7. Fast, easy setup
A domed-head tripod makes setting up faster and easier even on inclined and uneven ground. The B20 levels also fit flat- head tripods. The circular level can be seen on a pentaprism or plane mirror located beside the telescope eyepiece.
