Vortex 10x42 Diamondback HD Binoculars
Optical Performance

* High 10x magnification brings distant subjects in for close observations

* 42mm objective lenses have good light-gathering capability for use in challenging conditions, such as at dawn and dusk, without being too heavy or bulky

* Compact roof prism light path ensures performance without adding excessive weight and bulk

* Phase-correcting prism coatings eliminate internal interference to improve color and contrast

* Dielectric prism coatings boost internal prism reflectivity to greater than 99% to maximize light transmission through the prism with minimal loss and diffraction

* High-density (HD), extra-low dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view

* Anti-reflection fully multicoated optics increase light transmission for accurate color fidelity and improved contrast and clarity

* ArmorTek exterior lens coatings resist scratches and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue

* Short 5-foot close focus distance is ideal for making detailed observations of small subjects like birds, bees, insects, flora & fauna at feeders and flower beds

* Wide 63° apparent angle of view helps to reduce the appearance of the distracting hand shake that is common when holding high-power optics such as this

* 330-foot field of view at 1000 yards

Use and Handling

* Closed bridge configuration provides a solid platform for the internal focusing mechanism

* Large slip-resistant center focus knob is easy to manipulate in cold and wet weather or while wearing gloves

* Right eye dioptric correction lets you compensate for individual eye prescription for tack-sharp views

* 55-73 mm interpupillary distance range allows easy viewing by a wide variety of users

* Twist-up click-stop rubber eyecups for comfortable use with or without eyewear

* Tripod mountable with an optional adapter for hands-free use to reduce vibration and arm fatigue

* 15mm eye relief reduces eyestrain to make for more comfortable viewing

* 4.2mm exit pupil will completely cover most pupils as they open and dilate in low light to ensure the whole scene remains in view without vignetting

Construction Details

* Short bridge design provides more gripping area on the optical tubes for steadier views and more room for larger hands

* Magnesium alloy chassis reduces weight without sacrificing strength or stability

* Rubber armoring provides protection from bumps and impacts while offering a positive slip-resistant grip in cold and wet weather

* O-ring sealed and argon-filled to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions

* Tethered objective lens caps and one-piece ocular rainguard protect the lens surfaces without the fear of losing them when not in use

* GlassPak binoculars harness & case holds the optic close to your body to keep it safe and secure without swinging or hanging when moving or climbing over rough terrain
