Levenhuk Monaco ED 12x50 binoculars feature high magnification and excellent light-gathering power in an all-weather, shock-proof shell. They transmit a sharp and clear image even in low illumination conditions such as twilight, dawn, or cloudy weather. The extra-low dispersion optics and multiple-element objective lenses and eyepieces eliminate optical aberrations, providing a magnified, detailed image across the entire field of view. With 12x magnification, these binoculars are suitable for extreme conditions.

The extra-low dispersion optics enhance image sharpness and detail while preserving the natural colors of the surroundings. Stray glare is minimized, resulting in a true-to-life, stereoscopic image. The multiple-lens optics, including five-element eyepieces and four-element objective lenses, improve overall image quality. The external surfaces of the optical elements are coated with multiple layers, allowing for the discernment of details in low illumination.

The binoculars' body is made of shock-proof, temperature-resistant plastic, making them impervious to falls, moisture, dust, shaking, and impacts. Their hermetic design prevents water penetration, allowing the binoculars to survive immersion in water, though they should not be left underwater for longer than three minutes or deeper than 1.5 meters (5 feet). Filled with nitrogen, these binoculars protect the lenses from condensation and prevent fogging.

Levenhuk Monaco ED 12x50 binoculars include essential features such as diopter adjustment on the right eyepiece, interpupillary distance adjustment, and smooth focusing. Twist-up eyecups can be adjusted for comfortable viewing with or without glasses. The binoculars are also adaptable to a tripod (sold separately).
