Extra-low Dispersion Glass: ED lens (Extra-low dispersion glass) for chromatic aberration compensation and brighter, clearer viewing.

　Phase Coating: Phase Coating of roof prism for color reproduction and high resolution.

　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.

　Argon Filled: Argon Filled is batter than Nitrogen Filled and has a lower thermal conductivity. It can effectively resist oxidation, corrosion and fogproof.

　Pocket: Compact and small, light weight. Easy to carry and put into pocket.

　High Reflection Dielectric Coating: High Reflection Dielectric Coating is a coating with high reflectivity, which can transmit lights with less loss than silver and aluminum coating to obtain higher transmittance.

　Ultra High Definition: UHD (Ultra High Definition) optical system captures more image details.

　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.

　Aluminum Alloy: Aluminum Alloy body chassis makes the products to be durable, stable, falling resistance and used in the situation with obvious temperature variation.

　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.
