Description
Steiner-Optik Navigator - 7x50 (2021) arrives as a robust maritime binocular designed for demanding conditions, introduced in 2021 to meet the needs of professional and recreational seafarers.
This Steiner-Optik Navigator - 7x50 combines a 7x magnification with a generous 50 mm objective diameter, producing an exit pupil of 7.14 mm and a twilight factor of 18.7 for bright, clear views in low-light conditions.
The housing is built from durable rubber and polycarbonate (PC) and is finished in black or blue, offering a secure grip and rugged protection. The binoculars are fully waterproof to depths of up to 5 m and operate reliably in temperatures from -20 to 70 °C.
Optical comfort is enhanced by Steiner-Auto-Focus, a wide field of view of 128 m at 1000 m, and diopter compensation of ±5. The adjustable interpupillary distance ranges from 5.6 cm to 7.2 cm to suit different users, while the device includes both a neck strap and lens cap for convenience.
With dimensions of 208 mm (width) x 70 mm (depth) x 140.5 mm (height) and a weight of 1.04 kg, the Navigator - 7x50 balances portability with a solid, seaworthy presence. Its combination of waterproofing, temperature tolerance, and comfortable optics makes it ideal for long watches and offshore use.
Suggested use cases include marine navigation, coastal surveillance, yacht cruising, search and rescue observation, and wildlife watching from deck. The binoculars are particularly well suited to users who need reliable performance in rough weather and low light.
Key selling points are the 7x magnification with a large 50 mm objective, Steiner-Auto-Focus for instant sharpness, waterproofing to 5 m, wide 128 m field of view, and rugged rubber/PC housing. These features make the Steiner-Optik Navigator - 7x50 (2021) an excellent choice for maritime and outdoor enthusiasts.
