    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.

    UHD Glass - no dispersion glass gives you a very low chromatic image, so the end effect is the best and most accurate, and clearest image in your eyes.

    E2ES Method is a system of field flattening that creates better and sharp images.

    ESP Dielectric Coating is a prism coating in many layers that mirrors about 99 percent of the light on your eyes and produces a sharp, transparent picture that demonstrates exact light output.

    XPL Coating provides you added protection from grit, grease, and bruises on the external lenses..

      I’ve used a lot of different binoculars over the years even borrowed some really high dollar ones but never once until now, that I’ve got the CRONUS 10 x 42 have I seen things so clearly. I have found the right ones now. Clearer than the high dollar ones at a very reasonable cost. Athlon is Definitely worth the 5 star rating!

    2. Christopher Sirakowski

      I received my Cronus 10×42 binoculars just three days ago. Since that time, I’ve taken them to wildlife preserves and out to the coast. The degree of visual clarity is amazing for both birding and land animal observation. As a wildlife biologist, it’s going to be difficult to leave the house without my binos from here on out.

    3. Evan Rivera

      These binoculars give you the clearest image ever. The eye cups are really comfortable and easy to adjust. I would recommend anyone to get these either as a gift or for themselves.
