Every angle

A comfortable all-rounder for long days outside.

The true open hinge gives the fingers a natural place to settle, while textured rubber armour adds grip and protection without making the 8×42 feel oversized in the hand—useful for birding walks, travel, wildlife watching and everyday carry.

HD optical system

Clarity where detail matters.

Select glass elements are optimised for resolution and reduced chromatic aberration, helping fine edges appear cleaner while colours remain natural across the view.

Fully multi-coatedAnti-reflective coatings on every air-to-glass surface improve transmission, clarity and lower-light performance.

Dielectric prismsMulti-layer prism coatings support a bright, clear and colour-accurate image.

Phase correctionRoof-prism phase coating enhances resolution and contrast where fine structure matters.

ArmorTek®An ultra-hard exterior-lens coating helps resist scratches, oil and dirt.

The optical system combines select glass, full multi-coating, dielectric prism coating and phase correction to preserve useful image information through the roof-prism path.

Field of view

120 metres of view at 1,000 metres.

The wide 7.5° angular field makes it easier to scan tree lines, coastlines and open country, pick up a bird quickly and keep moving wildlife in view. The steadier 8× image is also comfortable for relaxed, extended observation.

Controls and connection points

Fast, familiar control.

A central focus wheel, right-eye dioptre and adjustable eyecups make everyday setup intuitive, while the concealed front socket accepts a compatible binocular tripod adapter.

1Twist-up eyecups

Raise for viewing without glasses or collapse for most spectacle wearers.

2Centre focus

Moves both optical channels together for fast near-to-far focusing.

3Right dioptre

Balances the right channel to the viewer’s eyesight across a ±4 range.

4Open hinge

Adjusts the 55–73 mm interpupillary distance and gives the fingers a secure hold.

5Strap lugs

Accept the comfort neck strap or GlassPak tether straps supplied in the box.

642 mm objectives

Gather light for a practical 5.25 mm exit pupil in a portable full-size body.

7Adapter socket

Remove the front cap to fit a compatible Vortex binocular tripod adapter.

Hunting capability

A capable field optic when the focus turns to hunting.

The same wide, steady 8× view that works so well for birds and wildlife also suits close-to-mid-range hunting, where fast subject acquisition and comfortable handheld glassing matter. At 21.8 oz / approximately 618 g, the Diamondback HD 8×42 remains manageable on long days while retaining full-size controls and versatile 42 mm objectives.

Wide 7.5° fieldHelps locate and follow subjects quickly through bush, scrub and mixed terrain.

17 mm eye reliefAdjustable eyecups support a comfortable, full viewing position with or without glasses.

Rubber armourTextured external protection supplies a durable, non-slip hold in changing conditions.

GlassPak™ carryKeeps the binocular protected at chest height and ready for quick access on the move.

All-condition construction

Built for changing conditions.

O-ring sealing, argon purging, shock-resistant construction and ArmorTek® exterior-lens protection help the Diamondback HD stay ready through changing weather, temperature swings and regular field use.

Waterproof

O-ring sealing is designed to resist harsh weather and prevent moisture from entering the optical system.

Fogproof

Argon-gas purging helps prevent internal fogging through wide temperature changes.

Shockproof

Rugged construction is designed to withstand the impacts and knocks that come with outdoor use.

ArmorTek®

The ultra-hard exterior-lens coating helps protect against scratches, fingerprints, oil and dirt.

Personal setup

Tune the binocular to your eyes.

Set the eyecups, barrel spacing and right-eye dioptre once for a comfortable view, then use the centre focus wheel for normal near-to-far focusing.

Set eyecups and spacing

Extend the eyecups when viewing without glasses or collapse them for most eyewear. Pivot the barrels until the two views merge into one clean circular image without dark edge shadows.

Focus the left channel

Choose a detailed object about 20 yards / 18 metres away. Cover the right objective or close the right eye, then use the centre wheel until the left-eye image is sharply focused.

Calibrate the right dioptre

Cover the left objective or close the left eye. Turn only the right dioptre until the image is sharp, then note its position. Normal focusing can now be handled with the centre wheel alone.

GlassPak™ included

GlassPak™ included for secure carry.

The supplied GlassPak binocular harness carries the optic against the chest for quick access and improved comfort over extended use. Adjustable shoulder straps distribute the load, while binocular tethers add security against accidental drops.

Care in the field and at home

Keep the view clear.

Clean coated lenses carefully

Blow away dust and grit before touching a lens surface.
Use a clean lens cloth and products intended for coated optical glass.
A small amount of water or pure alcohol can help release stubborn dried water spots.

Protect and store

Fit the objective covers and Rainguard whenever the binocular is not in use. Avoid leaving it in direct sunlight or a very hot location for extended periods.

Keep the sealed system intact

Internal components are permanently lubricated and need no additional lubricant. Do not disassemble the binocular beyond removing the supplied covers or tripod-socket cap.
