The Leica 8x20 Waterproof Monovid Monocular is a compact and lightweight device, weighing just 0.9 pounds, making it easy to carry along for various outdoor activities like hunting. It offers 8x magnification, providing a clear and detailed view of distant objects. The 42mm objective lens diameter ensures good light transmission, which is essential for clearer and brighter images, especially in lower light conditions.

One of its standout features is the close-up accessory lens, allowing for close focusing distances as short as 9.8 inches when attached, which adds versatility for observing small details at short distances. The nitrogen filling prevents internal fogging, and the AquaDura lens coating helps repel water and dirt, making it highly reliable in adverse weather conditions. The central focusing knob offers easy and precise adjustments, and the roof prism with phase correction coating enhances image clarity and sharpness.

At a price point and with a brand like Leica, it might be considered an investment piece, which could be a drawback for those on a tighter budget. Despite its small size, some users might find the 1.5-inch width and height slightly challenging to handle if they prefer a more robust grip. Additionally, while the monocular is waterproof up to 5 meters, it may not be suitable for extreme underwater activities. This monocular is best suited for outdoor enthusiasts who require a high-quality, durable, and versatile viewing device for detailed observation in various conditions.

The Bushnell Legend 10x42 Ultra HD Monocular is a strong contender in the high-power monocular category, particularly suited for hunting, wildlife observation, and birdwatching. Its 10x magnification is versatile enough for various activities, providing clear and detailed views. The 42mm objective lens diameter allows for impressive light gathering, which, combined with advanced ED Prime glass and Ultra Wide Band Coating, results in excellent clarity, color fidelity, and resolution even in low light conditions. These features make it ideal for early morning or late evening use when wildlife is most active.

The monocular's durable design, including a rugged rubber-armored exterior and O-ring sealed optics, ensures it can withstand tough outdoor conditions, remaining waterproof and fog proof. This durability makes it reliable in all weather conditions. Weighing 374 grams and with compact dimensions, it is easy to carry and handle, making it a convenient option for long hikes or extended use. The adjustable eyecup is a thoughtful addition, providing comfort for users with and without glasses.

However, the manual focus feature might take some getting used to for those accustomed to automatic focusing systems. Additionally, while the monocular's high-quality optics and robust design are major strengths, its tripod mount may not be as essential for all users, particularly those who prefer handheld use. In summary, the Bushnell Legend 10x42 Ultra HD Monocular stands out for its optical performance and ruggedness, making it an excellent choice for serious outdoor enthusiasts looking for reliable, high-quality magnification.

The 12x56 High Power Monocular Telescope offers a strong 12x magnification and a wide 6.5° field of view, making it suitable for activities such as bird watching, hiking, and camping. The large 56mm objective lens and 25mm eyepiece ensure that you get a clear, bright view.

Additionally, the BAK4 prism and Fully Multi-Coated (FMC) lens enhance light transmission and reduce reflections for high-contrast, color-accurate images. This monocular is designed for ease of use, whether you wear glasses or not, and it includes a smartphone holder and tripod, which are both adjustable and sturdy. The included travel bag adds convenience and protection during transport.
