    About

    Edge-to-Edge-Sharpness System is a field flattening system that produces sharper, clearer images all the way from one lens edge to the other.

    ED Glass- High Definition Glass gives you an image with little or no chromatic fringe, so the final image results in the clearest and sharpest image to your eyes.

    Enhanced Spectral Prism Dielectric Coating is a multi layer prism coating that reflects over 99% of the light to your eyes bringing you a clear, bright image that displays accurate color reproduction.

    Lightweight Magnesium Chassis provides the strength of a metal chassis while reducing the weight as much as 35%.

    Xtra Protective Layer Coating enhances protection on the exterior lenses from dirt, oil, and scratches.

    Phase Corrected prisms produce images that have better contrast, a higher resolution, and better color reproduction.

    BaK-4 Prisms reflect more light to your eyes which will give you a brighter and sharper image.

    Advanced Fully Multi-Coated Lenses allow for better light transmission to bring optimum brightness and true color across the entire light spectrum.

    Locking Diopter keeps the diopter adjustment knob from accidentally moving from the optimal setting.

    Long Eye Relief is particularly vital for eyeglass wearers because longer eye relief allows them to still see the entire field of view.

    Close Focus is important for those who prefer to be up close and personal with nature.

    Twist-Up Eyecups with intermediate stops allow you to set the eyecups to the ideal eye relief.

    Waterproof protection against the harshest weather conditions or if accidentally submerged underwater.

    Argon Purged gives you better waterproofing and thermal stability.

    BaK4 GLASS PRISMS

    reflect more light to your eyes and will give you brighter and sharper picture.

    MULTICOATED OPTICS

    effectively decreases reflecting light and improves the propagation of light making you a clearer vision than standard single coated lenses

    LONG EYE RELIEF

    can be especially valuable for eyeglass wearers since longer eye relief enables them to still see the whole field of view.

    TWIST-UP EYECUPS

    with intermediate stops allow you to set the eyecups to the perfect eye relief for you

      For the price, these are really great optics. Clear, light, easy to use. Took them elk hunting in Colorado, what a great buy!

    2. Mia Torres

      I bought these binoculars for an upcoming trip to Alaska. All the other binoculars in this price range would have involved some kind of compromise, either a narrow field of view or a of lack of ED glass or a long minimum focusing distance. These binoculars ticked all the boxes for me, and I stayed within my budget (although it was the high end of my budget).

      Even though I am no expert, I am impressed. These binoculars are very comfortable in my small hands. They are solid without being unwieldy. The focusing is smooth and easy. Also, I am impressed with how bright they are in low light. The binoculars arrived late in the day, and I gave them their first test drive.

      No regrets here. I would highly recommend these binocular

    3. Connor Robinson

      I have the Swarovski 10×42 but not the 8.5×42 so I bought this binoculars to pair with my 10x in order to cover different magnifications. The optics is so excellent that I bought two pairs of Cronus 10×42 for work purposes. They are almost as good as my Swarovski. The major complaint about this binoculars is that the hinges are very stiff (requires 2 hands) and the focusing knob is very tight (requires 2 fingers) but I have read reviews that they will loosen up after some usage. The rubber armour is also less pleasant to hold compared to my swarovski due to the texturing. The case is very basic etc. But at this price I should not be complaining.
