Best Monoculars For Surveillance - Up to 35mm Lens Diameter

The main consideration when selecting a monocular are the magnification level and objective lens diameter, which determine the optical capabilities of the monocular. The bigger the objective lens diameters, the better the image quality and the heavier the monocular may get. Waterproofing and night vision (thermal or infrared) are also important factors to consider when selecting a monocular.

Surveillance optics focus on stealth and a wide field of vision for monitoring large areas. A modest 5x to 8x magnification allows the user to keep a stable eye on a target without losing track of the surrounding environment. The 25mm to 40mm objective lens provides a slim profile that is easy to conceal while still maintaining enough clarity for identification. Many of these units are finished in matte, non-reflective coatings to ensure the observer remains undetected during stationary operations.

Compact monoculars with an objective length diameter of less than 35mm are very small and lightweight. They are ideal for backpacking, theater shows, and sports event. For nature viewing, consider at least 35mm diameter, but if you need a really light monocular, try the 25mm size.
