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
110 metres of terrain at 1,000 metres.
A 6.3° angular field balances the reach of 10× magnification with enough surrounding context to search open faces, follow moving wildlife and reacquire a subject after lowering the binocular.
Controls and connection points

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.
