40x60 BAK4 Prism Waterproof Monocular

Weighing 380 g and measuring 15.2 cm, this monocular has a 60 mm objective lens and delivers true 40x magnification. Its optical path uses BAK4 prisms and fully multi-layer coated lenses to enhance resolution, contrast and colour accuracy. The housing is hermetically sealed with O-rings and filled with dry nitrogen, making it both waterproof and anti-fog. The 52 mm wide-angle objective lens enables an unusually broad field of view for its magnification class, supporting intuitive subject acquisition and comfortable panning. Lens coatings suppress flare and ghosting, while BAK4 glass ensures clean, circular exit pupils for optimal eye relief and edge sharpness. Practical for everyday outdoor pursuits: track deer across fields, identify birds in hedgerows, monitor traffic flow from elevated viewpoints, or appreciate architectural details on city walks — all with a tool that fits easily into a coat pocket or daypack.
