SIRUI Beyond Series Laser Rangefinding Binoculars features outstanding optical
performance and precise distance measurement with the ranging capacity of 1800m. Clear data, such as
distance and angle is shown on the LED high transmittance screen. And the automatic power off design
helps use less power. Solid built outside and convenient operation binoculars is born for long-distance
observation and accurate measurement, such as hunting, adventure, bird watching, geological prospecting,
building surveying, etc.
Accurate Measurement
Binoculars is designed with ranging capacity of 1800m/2000yd. Besides, the
tested information and what you are watching will come into view at the same time. It also features
fast measurement speed and angle measurement, suitable for long-distance observation and accurate
measurement such as wildlife observation, forestry surveying, building surveying, etc.
Wide Field of View
Field of view (FOV) is the area or range of what can be seen or captured
by a device or sensor. The wider the FOV, the more the set is visible.The FOV of SIRUI B1042B
binoculars is 114.3m@1000m, which means you can see a circular area of 114.3m diameter when the
object is 1000m away. Wide FOV is perfect for capturing moving object.

BAK4 Prism
BAK4 is a type of high-density glass. BAK4 prisms are made of a higher
quality glass than the lower-cost BK7 prisms that are sometimes used in binoculars. The higher
quality glass used in BAK4 prisms results in a brighter and clearer image, especially suitable for
viewing in low-light situations.
BAK4 Prism
Multi-layer Coating
Multi-layer coating glasses with anti-reflective surface provide higher
light transmittance up to 92.5%.
Lens Protector
Solid quality construction with anti-scratch and anti-fouling coating.
