The large lenses draw in a generous amount of light and, combined with 10x power, translate to a comfortable exit pupil that will completely cover most pupils in low-light condition at dawn or dusk and when peering into heavy brush or canopies. Complementing these performance features are anti-reflection fully coated optics, a wide field of view, and a traditional Porro prism optical path that all work together to produce an immersive and comfortable observational experience defined by bright, clear high-contrast views with accurate colour rendition and a rich depth of field. The wide field of view also helps to mitigate the appearance of visible handshake that is common with higher power optics, for clearer views.
For long-duration glassing sessions, to reduce arm fatigue, or to eliminate vibrations, this Ultima binocular can be tripod mounted using an optional adapter. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging. The chassis is made of a lightweight and durable aluminium alloy and wrapped in a protective slip-resistant synthetic rubber armour. Fold-down rubber eyecups mould themselves to your eye sockets to block stray peripheral light for brighter views without intrusive side glare, and the binoculars' centre-focusing wheel is also slip-resistant to make precision focusing fast and easy.
