Purpose-built optics

The Vortex Diamondback HD 10x42 binoculars combine 10 magnification with a 42 mm objective lens for bright, detailed viewing in a roof-prism chassis. Fully multi-coated glass and dielectric prism coatings maximize light transmission, while argon purging and waterproof construction protect internal optics from moisture and fog. A rubber-armor finish and ArmorTek lens coating resist scratches and impacts during field use.

Ideal users and limits

Hunters, birders and outdoor observers who want a single versatile glass for mid-range detail will appreciate the 6.3-degree angular field and 330-foot linear field at the rated distance. The 15 mm eye relief suits eyeglass wearers, and the interpupillary range of 55 to 73 mm fits most adults. Buyers who need higher magnification for extreme distance, a wider exit pupil for low light, or a more compact form factor for pack-constrained trips should consider other configurations.

Deciding specification

The 4.2 mm exit pupil — derived from the 10 magnification and 42 mm objective — determines how bright the image appears in twilight conditions; a 20.5 twilight factor confirms strong performance in fading light.

Questions about this item

Will the 10x magnification and 42 mm objective lenses work with my existing tripod adapter?

The binoculars use a standard center-focus roof-prism body; most universal tripod adapters that clamp to the hinge will fit, but check the adapter's width range against the 55–73 mm interpupillary distance.

How can I verify the optics are performing correctly after I take them out of the box?

Aim at a high-contrast target in daylight; the 6.3° angular field should show a crisp, color-fringing-free image from center to edge, and the 15 mm eye relief lets you see the full field with or without glasses.

What accessories come in the box and what must I buy separately?

Included are tethered objective lens covers, a comfort neck strap, a Rainguard eyepiece cover, and a GlassPak bino harness; a tripod adapter and cleaning kit are not included.
