10 Best Monoculars 2025 in the United States

The Vortex Optics Solo Monocular 10x36 is a compact and lightweight option for anyone looking to enhance their outdoor viewing experience. With 10x magnification and a 36mm objective lens, it excels at providing clear, detailed images in various lighting conditions, thanks to its fully multi-coated lenses that improve light transmission. The rubber armor not only offers a non-slip grip but also adds to its durability against drops and impacts, making it a reliable companion for hiking, birdwatching, or sporting events.

One of the standout features is its waterproof and fogproof design, which ensures functionality in wet or humid environments, a significant advantage for outdoor enthusiasts. The adjustable eyecup is another plus, allowing users to easily customize their viewing experience whether they wear glasses or not.

However, there are a few considerations to keep in mind. While the 10x magnification is ideal for most casual users, those seeking extreme long-range viewing might find it somewhat limited compared to higher-powered models. Additionally, being lightweight means it may not feel as robust as some bulkier options, although this is a common trade-off in compact designs. The monocular is highly portable, weighing only 9.7 ounces, which is a definite advantage for travelers. The included utility clip allows for convenient attachment to bags or clothing, enhancing its accessibility on the go.

The Nikon Monarch M5 8x42 Binocular is a solid choice for those in need of a reliable and high-quality pair of binoculars. With an 8x magnification and a 42mm objective lens diameter, it offers a clear and bright viewing experience, which is well-suited for bird watching, hiking, and general outdoor observations. The use of Nikon’s Extra-low Dispersion (ED) glass lenses ensures superior image quality with minimal chromatic aberration, delivering sharp and vibrant visuals. Additionally, the lenses are phase-corrected and dielectric-coated, further enhancing image clarity and brightness. Its waterproof and fogproof design, achieved through nitrogen purging, makes it a robust option for use in various weather conditions, giving you peace of mind when using it in the great outdoors.

The long eye relief and twist-up click-stop eyecups provide comfort, making it easier for eyeglass wearers to use. The rubber-armored exterior offers shock resistance and a firm grip, which is extremely beneficial during active use. However, the binoculars weigh 1.39 pounds and are relatively compact at 5.7 x 5.1 x 2.1 inches, making them portable but possibly a bit bulky for some users. The locking diopter control is a thoughtful feature that maintains your personal settings, which can be convenient during extended use.

This binocular is perfect for enthusiasts and serious users who value high performance and durability in their optical equipment. Despite possibly being overkill for casual users who may not need all the advanced features, its design and functionality cater well to those seeking a high-quality viewing experience.

The Vortex Optics Solo Monocular 10x25 is a compact and lightweight option that offers 10x magnification with a 25mm objective lens. Its fully multi-coated lenses ensure enhanced light transmission and clear, crisp images, which is a significant advantage for those needing detailed views. The monocular is durable, featuring a fully rubber armored body for a non-slip grip, making it suitable for rugged outdoor use. It is also nitrogen purged and o-ring sealed, providing waterproof and fogproof performance in various environments—ideal for hiking, birdwatching, or other outdoor activities.

The adjustable eyecup is a thoughtful addition, allowing for comfortable use whether you wear glasses or not. One standout feature is the Vortex VIP Warranty, offering an unlimited, unconditional lifetime promise to repair or replace the monocular if it becomes damaged or defective, although it doesn’t cover loss or cosmetic damage. The fixed focus type may limit its flexibility for some users, and the 25mm objective lens, while sufficient for general use, might not perform as well in low-light conditions compared to larger lenses.

Weighing 5.6 ounces, it is lightweight, but some users might prefer an even lighter option for extensive travel. This monocular is an excellent choice for outdoor enthusiasts seeking a reliable and sturdy viewing device with clear optics and a robust warranty.
