16x52 High-Power Monocular with BAK4 Roof Prisms and Wide Field of View

This monocular offers a practical optical solution for users seeking significant magnification in a singular, handheld format. With its 16x power and 52mm objective lens, it is designed for detailed observation of distant subjects, from wildlife and landscapes to events. The inclusion of a BAK4 roof prism system and specific lens coatings supports image clarity, while its stated waterproof nature adds utility for use in damp conditions. Weighing 290g and measuring 145mm in length, it presents a portable alternative to bulkier binoculars for hobbyists, travellers, and outdoor enthusiasts.

Features and Construction

The monocular's performance is defined by several key specifications that determine its viewing capabilities and practical handling.

Optical Specification

The core specification is 16x52, indicating 16 times magnification paired with a 52mm diameter objective lens. The larger objective lens aids in light collection, which can be beneficial in lower light conditions. The stated field of view is 66 metres wide when viewing a target 8000 metres away, providing a reasonably broad perspective for a high-magnification device. The minimum close focus distance is 1.5 metres, allowing for observation of nearer subjects.

Internal Build and Coatings

Internally, the optical path uses a roof prism system constructed from BAK4 glass, a material noted for its optical properties in prisms. The lenses feature a high-definition green film coating, a treatment applied to optical surfaces to manage light reflection and transmission. The focusing mechanism is central, operated via adjustment of the eyepiece.

Physical Design and Durability

The monocular's external dimensions are 145mm in length and 52mm in diameter, contributing to its one-handed portability with a net weight of 290 grams. It is supplied in a black finish. A key practical feature is its waterproof construction, designed to protect the internal optics from rain and moisture. It is important to note the manufacturer's specification that this waterproofing does not support diving or submersion.

Uses and Placement

This instrument's specifications make it suitable for a range of observational scenarios, both recreational and semi-professional.

Outdoor and Nature Observation

The 16x magnification and wide field of view are well-suited for birdwatching, wildlife spotting, and surveying landscapes from a fixed vantage point. The waterproof feature adds reassurance during use in unpredictable outdoor weather, from light rain to misty conditions.

Event Viewing and General Use

For spectators at sporting events, concerts, or air shows, the monocular offers a powerful yet compact way to bring distant action closer. Its single-eye design can be easier to manage quickly than binoculars. The 1.5m close focus also allows for detailed inspection of objects like coins, insects, or museum displays.

Benefits and Buying Value

The value of this optical tool lies in its specific combination of power, portability, and stated protective features.

Portability and Ease of Use

Weighing under 300g, it is light enough for extended handheld use or to be carried in a jacket pocket or small bag, making it more convenient than many full-sized binoculars. The simple eyepiece focusing provides straightforward operation for most users.

Why Choose This Monocular

This product presents a clear choice for users prioritising high magnification in a truly one-handed format. The BAK4 prisms and green film coatings indicate an attention to optical performance within its category, while the explicit waterproof rating (excluding diving) offers a tangible, practical benefit for outdoor enthusiasts over non-protected models. Its value is in delivering these specific, measurable features in a single, integrated device.
