10 Best Pocket Monocular 2025 in the United States

The Leica 8x20 Waterproof Monovid Monocular is a compact and lightweight device, ideal for those who need a portable and reliable monocular. With an 8x magnification and a 42mm objective lens diameter, it offers clear and detailed views. The close-up converter lens allows for a close focusing distance of approximately 1.8 meters, which can be further reduced to 9.8–11.8 inches, making it versatile for different viewing needs, including close-up observations.

Its nitrogen filling and AquaDura lens coating provide excellent protection against water, fog, and dirt, ensuring clear visibility in various weather conditions. The phase correction coating on the roof prism enhances image quality by improving contrast and resolution. Weighing only 0.9 pounds and measuring 3.9 x 1.5 x 1.5 inches, it is easy to carry around.

The price might be a consideration for some, given its high-end features. It ranks well in customer reviews with a 4.5-star rating, indicating user satisfaction. This monocular is particularly suited for hikers, bird watchers, and hunters who require a durable and high-performance optics solution.

The RIX Pocket K2 Portable Thermal Monocular excels in several key areas for a pocket-monocular, particularly in its lightweight and compact design. Weighing only 7.1 ounces and with dimensions smaller than most smartphones, it is ideal for carrying around during outdoor activities such as hunting, hiking, or exploring, fitting easily into your pocket.

Its 256x192 resolution with NETD<25mK and a 50Hz refresh rate makes it a strong performer in detecting subtle temperature differences, which is crucial for night vision and thermal imaging tasks. The 800x600 OLED display ensures a clear and detailed visual experience, enhanced further by the Resolution Enhanced Technology (RET) that improves image clarity significantly. The integrated lens cover design is a practical touch that prevents the common annoyance of misplaced lens covers, contributing to the device’s convenience and usability.

Another notable feature is its IP67 waterproof rating, which ensures it can withstand tough conditions like rain and fog, making it highly reliable for outdoor adventures. However, the monocular has a relatively small objective lens diameter of 9mm, which might limit its light-gathering capability in extremely dark conditions. Additionally, the fixed focus type may not be as versatile for users who need to adjust focus for different distances frequently. The monocular is also dependent on a battery (included), which means you must ensure it's charged before heading out for extended periods. Despite these minor drawbacks, the RIX Pocket K2 stands out for its impressive thermal detection, portability, and durability, making it a highly appealing choice for outdoor enthusiasts seeking a reliable night vision device.
