Further details

They are fully waterproof (IPX7 standard, 1m depth for 30 minutes) and nitrogen filled for clear fog-free operation, with individual eyepiece (IF) focusing and designed for medium-to-long-range terrestrial and astronomical observations.

The body material is constructed from magnesium alloy making the binocular extremely lightweight for an instrument of this size, whilst maintaining a very robust structure. The body is covered in stylish hard textured leatherette.

Features high-index BaK-4 prisms and a fully broadband multi-coated optical system and shockproof caged prisms. The high-resolution optical system features high-transmission lens and prism coatings allowing a massive light throughput equal to or exceeding 90%. The lens coatings have an extremely low level of reflectivity, ensuring the maximum amount of precious light is provided at the eyepiece. Images delivered are vibrant, very flat edge-to-edge and virtually distortion free.

The eyepiece design 5 elements/4 groups, features oversized eye lens elements for comfortable viewing. Fold-down rubber eyecups are provided for spectacle-wearers.
