Excellent performance underany condition
Get outstanding precision for all your leveling tasks. The B-series 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
- 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.
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. Two-speed focus
knob (B20) switches between coarse
and fine for even faster operation. - 30 cm from instrument center
Stadia
Stadia lines on the reticle allow distance
measurements. Simply multiply the staff
length between the top and bottom
stadia lines by 100.
