β2 贝塔2(42) Series

β2 贝塔2(42)系列双筒望远镜产品镜体采用PPS(塑钢镜体)材质,具备耐腐蚀性和高强度,确保产品结构稳定。其次,采用环保无色光学玻璃,使成像清晰,色彩丰富,呈现更真实的观测图像。此外,通过BAK4材质棱镜设计,整个系列产品体积更紧凑,便于携带和使用。最后,透镜采用先进的SMC(全光学超面宽带镀膜)技术,提高成像的明亮度,使观察体验更加清晰、明亮。防水设计和氮气填充确保适应各种复杂环境。无论您是户外探险、观鸟还是旅行,我们的双筒望远镜系列产品都能为您提供优质的观测体验。

 Super Fully Multi Coating: Super Fully Multi Coating is applied to transmission surfaces of all lenses. The image by SMC is clearer and brighter than FMC.
 Bak4 Material: BAK4 has higher light reflection than BK7. It can effectively shorten the optical path and make the structure of optical products more compact.
 Nitrogen Filled: Due to the lower preparation requirements for nitrogen compared to argon, it is cheaper.
 High Definition: HD (High Definition) optical system makes images cleaner and sharper.
 ShuntuCare: It doesn't matter how it happened, whose fault it was. If you ever have a problem, no matter the cause, we promise to take care of you.
 IPX7: Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.

SMC

Super multi coating is applied to transmission surfaces of all lenses. The image by SMC is clearer and brighter than FMC.
80% Light Transmission

It can obtain brighter images and natural colors in a well lit environment. Even in low light environments, it can clearly and accurately recognize the details of the target.
Wide-Angle FOV

The apparent FOV (47.5 ° for 8x42 and 53.7 ° for 10x42) allows users to have a more comfortable observation experience during outdoor activities.
IPX7 Waterproof And Argon Filled

Waterproof and argon filled, level IPX7, it can soak in 1 meter of water for 30 minutes without leaking. Fearless of extreme environments, able to operate normally in temperatures ranging from -20 ℃ to 55 ℃. When encountering rain, fog, cold or heat during outdoor observation or hiking, it can work normally.
Material BAK4

BAK4 has higher light reflection than BK7. It can effectively shorten the optical path and make the structure of optical products more compact.
Large Size Of Eyepiece

Eyepieces with larger aperture diameters (21mm for 8x42 and 19mm for 10x42) provide users with a more comfortable observation experience during outdoor activities.
42mm Effective Lens Diameter

HD (High Definition) optical system 5.6" for 8x42 and 5.6" for 10x42) makes images cleaner and sharper.
Reinforced Plastic Chassis & Environmentally Friendly Materials

The chassis is made of reinforced plastic material with high hardness and high temperature resistance. It can meet RoHS requirements. It is your good friend for outdoor hiking, traveling, bee hunting, bird watching.
Focusing+Diopter Locking

The diopter of the right eyepiece is ± 3 dpt, allowing users to obtain clear and bright imaging for both eyes during observation. The central focus wheel makes focusing more convenient and efficient, allowing for quick and easy capture of the observed object during observation.
3 Stage Twist-up Eyecups

Multi stage Twist-up Eyecups design, with adjustable distance in 3 stages. When using without glasses, Clockwise rotation the eyecups to prevent black shadows and shaking in the observation image, which may result in incomplete images. When wearing glasses, Anticlockwise rotation the eyecups.
Connect The Tripod

It has a tripod interface that allows the binoculars to be connected to the tripod. Prevent unclear imaging caused by shaking during use. Especially when using large-sized binoculars and observing for a long time, connecting a tripod can effectively avoid binoculars shaking and discomfort caused by prolonged use of hands.
