Is the Diamondback HD 10x42 good for birdwatching?

Yes, its sharp glass and compact roof-prism body suit birding. The 10x magnification gives reach, but the narrower field of view makes fast birds harder to follow than with an 8x.

How does it compare with the 8x42 version?

The 8x42 gives a wider field of view and steadier hand-held image; the 10x42 shows more detail at distance but is harder to hold steady and dimmer in low light.

Is it waterproof and fogproof?

Yes. O-ring seals keep out moisture and dust, and the optics are purged so they resist internal fogging in wet or cold conditions.

Does it work for people who wear glasses?

Yes. The eyecups twist up or down in multiple positions so glasses wearers can set the right eye relief.

What comes in the box?

The binoculars, a Glasspak harness and case, a neck strap, a rain guard for the eyepieces and tethered objective lens covers.

Is the lifetime warranty transferable?

Vortex's VIP warranty covers the binoculars for life against defects and accidental damage, and it stays with the product rather than the original buyer.

About the Vortex Diamondback HD 10x42 Roof Prism Binoculars

The Vortex Diamondback HD 10x42 is a roof prism binocular with 10x magnification and 42mm objective lenses. It uses High Density extra-low dispersion glass for resolution and color fidelity. The roof prism design makes it durable and compact, and it can be used for birdwatching, hunting or watching wildlife at home.

The lenses are fully multi-coated for increased light transmission. All air-to-glass surfaces have multiple anti-reflective coatings, and the prisms have multi-layer coatings for bright, clear, color-accurate images. The outer lenses have an ArmourTek coating, a hard, scratch-resistant layer that repels dirt, oil and fingerprint salts.

A rubber armor skin gives a non-slip, durable grip. Waterproof O-ring seals keep out moisture, dust and debris. The multi-position eyecups twist up or down for comfortable viewing with or without glasses, and a right eye diopter adjusts for different eyes. The binoculars come with a lifetime guarantee.
