How We Picked These Models
We looked at over 30 monoculars before narrowing it down to these eight. Our research focused on five key factors that matter most to real buyers.
Optical clarity was the first priority. We prioritized models with BAK-4 prisms and fully multi-coated lenses, which deliver sharper images and better light transmission than cheaper BK-7 prism designs.
Build quality came next. A monocular needs to survive drops on a trail or a sudden rain shower. We looked for rubber armor, O-ring seals, and nitrogen purging for fogproof performance.
Magnification and objective lens diameter were weighed against portability. A 10×36 strikes a great balance. A 12×55 or 80×100 gives more reach but adds bulk you will feel after a few miles.
The included accessories mattered too. Some models come with a smartphone adapter or tripod. Others keep it simple with just a lens cloth and carry pouch.
We noted what each kit actually includes.
Finally, we considered the owner track record. Verified buyer reviews and aggregate ratings across thousands of purchases gave us a clear picture of long-term reliability and common failure points.

This is the monocular that comes with a lifetime warranty you will actually use. Vortex covers the Solo 10×36 with their VIP unconditional guarantee, meaning if it breaks for any reason, they fix it for free. The fully multi-coated lenses and rubber armor deliver a crisp, bright image in a package that is fully waterproof and fogproof.
At 10×36, it strikes the ideal balance for day hikes. The 10x magnification brings distant trail markers or wildlife into clear view, while the 36mm objective lens gathers enough light for dawn or dusk use. It weighs about 10 ounces, which disappears into a jacket pocket or hip belt pouch.
Flaws but not dealbreakers. The 10×36 has a narrower field of view than lower-magnification monoculars, so you will need to steady it against a tree or rock for the best image. It also does not include a tripod adapter or phone mount. If you want to share those views, consider the
Gosky 12×55 further down, which comes with both accessories.
⚠Warranty: Register the warranty online after purchase. Vortex does not require a receipt for repairs, but keeping your packing slip helps.
Pros
- ✓Unconditional lifetime warranty from a respected optics brand
- ✓Fully waterproof and fogproof with O-ring seals
- ✓Compact design fits easily in a standard pocket
- ✓Excellent multi-coated lenses for bright, clear daytime views
Cons

This is the only monocular in this lineup that ships with a smartphone adapter and a tripod. The Gosky 12×55 uses BAK-4 prisms and fully multi-coated lenses to produce a bright, detailed image at 12x magnification. The 55mm objective lens pulls in a lot of light, making it a solid performer in low light conditions like early morning or late evening.
The included smartphone adapter clamps onto the eyepiece and lets you take digiscoped photos of distant birds or wildlife. The compact tripod helps stabilize the view at 12x, which is noticeably harder to hold steady than an 8x or 10x monocular. Aggregate user reviews consistently praise the image quality for the price.
Flaws but not dealbreakers. This is a larger monocular, weighing over a pound with the accessories. It will not disappear into a pocket. The included tripod is lightweight and works fine for phone use, but it is not sturdy enough for heavy camera gear. If carrying weight is your main concern, the
Nocs Provisions Zoom Tube 8×32 is much lighter.
⚠Compatibility: The phone adapter fits most smartphones, but check the clamp width against your phone case. Thick cases may require removal.
Pros
- ✓BAK-4 prisms and FMC lenses for excellent image quality
- ✓Comes with a smartphone adapter and mini tripod
- ✓12x magnification with a large 55mm objective lens
- ✓Strong owner satisfaction with the included kit value
Cons
- ✕Heavier and bulkier than compact monoculars
- ✕12x magnification requires a steady hand or tripod
- ✕Included tripod is not very sturdy for heavy use
Included Accessories
Phone adapter, tripod, pouch
Best for: Birders and wildlife watchers who want to capture digiscoped photos on their phone without buying extra accessories.

This is the lightest monocular in the lineup, built for ultra-light backpacking trips. The Nocs Zoom Tube 8×32 weighs just a few ounces, making it easy to clip onto a backpack strap or stash in a running vest. Its 8x magnification offers a wide field of view, which is ideal for scanning mountain ridges or following a moving trail runner.
The 32mm objective lens is on the smaller side, but it still delivers a bright image in good light conditions. The BAK-4 prism system provides sharp edge-to-edge clarity. The design is simple and minimalist, with a focus on durability and low weight over extra features.
Flaws but not dealbreakers. The 8×32 is not a low-light performer. If you plan to use it heavily at dawn or dusk, the larger objective lens on the
Adasion 12×56 will serve you better. It also lacks a tripod adapter and phone mount, so it is purely for direct viewing.
⚠Care: The lens caps are not tethered, so they can be lost easily on the trail. Consider a small carabiner for the carry pouch.
Pros
- ✓Extremely lightweight and compact for backpacking
- ✓Wide field of view is excellent for scanning landscapes
- ✓BAK-4 prism provides sharp edge-to-edge clarity
- ✓Minimalist, durable design with no fragile moving parts
Cons
- ✕Limited low-light performance due to 32mm objective lens
- ✕No tripod or smartphone adapter included
- ✕Lens caps are not tethered and can be lost easily
Best for: Thru-hikers, trail runners, and anyone who counts every gram in their pack and wants a wide field of view.

This is the model that pushes magnification to 80x, turning a monocular into a portable spotting scope. The 80×100 High Powered Monocular has a massive 100mm objective lens that gathers an enormous amount of light, allowing you to see details at extreme distances. It also includes a smartphone adapter and a phone mount, so you can capture images of the moon or distant landscapes.
The 80x magnification is a different beast entirely compared to the 10x or 12x models. You will absolutely need a tripod for any usable image. The included tripod is basic, so upgrading to a sturdier one is a good idea. Verified buyer reviews consistently mention the impressive zoom range but note the learning curve required to get a steady image.
Flaws but not dealbreakers. At 80x, the image quality is noticeably softer than lower-magnification models, especially at the edges. The field of view is very narrow, making it hard to locate distant objects. If you primarily need a monocular for hiking or quick wildlife spotting, a 10x or 12x model like the
Vortex Solo 10×36 will be much more usable and portable.
⚠Tripod: A sturdy tripod is essential for this monocular. The included tripod is a basic tabletop model. A full-size tripod will dramatically improve your viewing experience.
Pros
- ✓Extreme 80x magnification for long-range observation
- ✓Large 100mm objective lens for impressive light gathering
- ✓Includes smartphone adapter for digiscoping
- ✓Very affordable for the magnification level
Cons
- ✕Image clarity is significantly softer than lower power models
- ✕Very narrow field of view makes target acquisition difficult
- ✕Bulky and heavy, not suitable for hiking or backpacking

This is the only monocular in the lineup with an IPX7 waterproof rating, meaning it can be submerged in one meter of water for 30 minutes. The Adasion 12×56 is built for wet conditions, with a large 56mm objective lens and BAK-4 prism that deliver bright images even in low light. It comes with a phone adapter, a tripod, and a carrying case, making it a complete kit.
The 12x magnification is a sweet spot for many users. The included tripod helps stabilize the view at that power. Aggregate user reviews highlight the robust build quality and the value of the included accessories. The rubber armor provides a secure grip, even in wet weather.
Flaws but not dealbreakers. The IPX7 rating is a major plus, but some owners report that the rubber armor can feel a bit loose over time, especially if the monocular is frequently removed from the case. The included phone adapter works well, but it can be a bit fiddly to align perfectly with the lens. For a more compact option, the
Vortex Solo 10×36 is a better choice for day hikes where you prefer to travel light.
⚠Waterproof: The IPX7 rating applies to the monocular body, but the lens caps and phone adapter are not waterproof. Dry them off before storing.
Pros
- ✓IPX7 waterproof rating for use in heavy rain or wet conditions
- ✓Full kit includes phone adapter, tripod, and case
- ✓Large 56mm objective lens for good low-light performance
- ✓BAK-4 prism for sharp image quality
Cons
- ✕Rubber armor can feel loose over time for some users
- ✕Phone adapter can be fiddly to align
- ✕Heavier than compact monoculars at 12×56

This is the most affordable way to get 16x magnification in a waterproof and fogproof package. The Monocular Telescope High Power 16X52 offers a 52mm objective lens and a power prism design that delivers a surprising amount of reach for the price. It is built with a rugged rubber armor and includes a hand strap for secure carry.
The 16x magnification is a step up from the standard 10x or 12x, allowing you to see details at longer distances. The 52mm objective lens provides decent light gathering, though it is best used in good lighting conditions. It is also shockproof, which adds to its durability for outdoor use.
Flaws but not dealbreakers. At 16x, the image is noticeably shakier without a tripod, and the field of view is quite narrow. Some owners report that the focus ring can be a bit stiff out of the box, though it loosens up with use. If you need a wider field of view for scanning, the
Nocs Provisions Zoom Tube 8×32 is a better choice for trail use.
⚠Stability: 16x is very hard to handhold. Use a tripod or brace your arm against a solid surface for a clear image.
Pros
- ✓16x magnification for a very accessible price point
- ✓Waterproof, fogproof, and shockproof construction
- ✓Compact and lightweight for the power level
- ✓Includes a hand strap for secure carry
Cons
- ✕16x power is very shaky without a tripod
- ✕Narrow field of view makes target acquisition harder
- ✕Focus ring can be stiff initially
Best for: Budget-conscious buyers who want high magnification for static observation, such as nature watching from a blind or target shooting.

This is the simplest and most affordable entry point into the monocular world. The Monocular Telescope High Power 8×42 Monoculars offer a classic 8x magnification with a 42mm objective lens, providing a wide field of view that is perfect for beginners. It is waterproof, fogproof, and shockproof, making it a durable option for kids and adults alike.
The 8x magnification is very forgiving for handheld use, offering a stable image that is easy to focus. The 42mm lens gathers enough light for daytime and early dusk use. The included hand strap adds a layer of security. Verified buyer reviews consistently mention its value for the price, especially for introducing children to nature observation.
Flaws but not dealbreakers. The optical quality is not on par with the Vortex or Nocs models. You will notice some chromatic aberration in bright conditions. It also lacks a phone adapter or tripod, limiting its versatility. If you are looking for a more serious tool for regular use, the
Vortex Solo 10×36 is a significant step up in clarity and build.
⚠Care: The lens coatings are not as durable as premium models. Clean the lens gently with a microfiber cloth to avoid scratches.
Pros
- ✓Very affordable entry point for beginners or kids
- ✓8x magnification is easy to handhold and steady
- ✓Waterproof, fogproof, and shockproof for durability
- ✓Wide field of view suitable for general scanning
Cons
- ✕Optical clarity is not as sharp as premium models

Owner Verdict8.0
This is essentially the same 80×100 monocular as the green model above, but in a black finish. It offers the same extreme 80x magnification, the same large 100mm objective lens, and the same included smartphone adapter and tripod. The only difference is the color, which some users may prefer for a more discreet look.
The same caveats apply. The 80x power is very difficult to handhold and requires a solid tripod for any usable image. The image quality is softer than lower-magnification models, and the field of view is very narrow. It is best suited for static observation of the moon, distant mountains, or other stationary targets.
Flaws but not dealbreakers. The same limitations asthe green model, including the softer image at high power and the need for a sturdy tripod. If you are choosing between the two, pick the color that appeals to you more. For a more practical everyday carry, the
Vortex Solo 10×36 is a far more versatile tool.
⚠Tripod: As with the green model, a full-size tripod is strongly recommended. The included tabletop tripod is not stable enough for 80x viewing.
Pros
- ✓Extreme 80x magnification for long-range observation
- ✓Large 100mm objective lens for light gathering
- ✓Includes smartphone adapter for digiscoping
- ✓Black finish may be preferred for stealthy use
Cons
- ✕Image quality is soft at 80x magnification

Best for: Users who want the same extreme 80x power but prefer a black finish, perhaps for a more discreet appearance.
Buying Guide: Magnification, Objective Lens, and Build Quality
Choosing the right monocular comes down to a few key specs that directly affect what you will see and how you will carry it. Here is what matters most.
Magnification: How Much Power Do You Really Need?
Magnification is the first number in a monocular's name, like the 10x in 10×36. It tells you how many times closer an object will appear.
For most people, 8x to 10x is the sweet spot. These powers are easy to handhold and provide a wide, stable field of view. The Nocs Provisions Zoom Tube 8×32 and the Vortex Solo 10×36 are excellent examples of this range.
Higher powers like 12x, 16x, or even 80x bring more detail but also magnify every tiny hand movement. You will need a tripod for anything above 12x to get a clear image. The 80x models are essentially specialized tools for static observation, not for casual hiking.
Objective Lens: The Key to Brightness
The second number, like the 36 in 10×36, is the diameter of the objective lens in millimeters. A larger lens lets in more light, which means a brighter image, especially in low light conditions like dawn or dusk.
A 32mm to 42mm lens is fine for daytime use. A 55mm or 56mm lens, like on the Adasion 12×56, is better for low light. The 100mm lens on the 80x models is massive, but it comes with a huge weight and size penalty.
The trade-off is simple. Larger objective lenses mean brighter images but heavier, bulkier monoculars. Match the lens size to the lighting conditions you typically encounter.
Prism and Lens Coatings
BAK-4 prisms are superior to the cheaper BK-7 prisms. They produce a rounder, brighter exit pupil and sharper edge-to-edge clarity. All the models in this guide use BAK-4 prisms, which is a good sign.
Fully multi-coated lenses, where every glass surface has multiple anti-reflective coatings, increase light transmission and reduce glare. This results in a brighter, higher-contrast image. The Vortex, Gosky, and Nocs models all use these coatings.
Waterproofing and Build Quality
If you plan to use your monocular in rain or near water, look for O-ring sealed and nitrogen-purged models. These are labeled as waterproof and fogproof. The Adasion 12×56 even has an IPX7 rating, meaning it can survive submersion.
Rubber armor provides a secure grip and protects the monocular from drops. All the models here have it. A carrying case and lens caps help protect the optics when not in use.
Who Should NOT Buy a Monocular
A monocular is the wrong purchase for some buyers. Here is who they are and what to look at instead.
You Need Two Eyes for Comfort and Depth Perception
If you plan to spend hours scanning for wildlife or watching birds, a monocular can cause eye strain. Using one eye for extended periods is tiring.
Instead, consider a pair of binoculars. They provide a more natural, comfortable viewing experience with both eyes. Our guides on options for getting the best value or versatile all-around models can help you find the right pair.
You Need Maximum Low-Light Performance
Monoculars with smaller objective lenses, like 32mm, struggle in dim light. If you are doing serious dawn or dusk observation, a monocular may not gather enough light.
A binocular with a larger objective lens, such as a 42mm or 50mm, will give you a brighter image. For the best low-light performance, look at models designed for twilight use.
You Prefer a Hands-Free Experience
A monocular requires one hand to hold and focus. If you need to be hands-free for other tasks, like hiking with trekking poles or navigating a boat, it is not ideal.
A headlamp, a small flashlight, or simply using your eyes is more practical. If you need magnification, a monocular can be worn on a neck strap, but it will still need to be brought to your eye.
Final Verdict
After researching all eight models, the Vortex Solo Monocular 10×36 is the clear winner for most people. Its lifetime warranty, waterproof build, and excellent optical clarity make it a buy-it-for-life tool that will serve you on any hike.
Want to share views on your phone? The Gosky 12×55 HD Monocular Telescope BAK4 includes a phone adapter and tripod, making it the best choice for digiscoping.
Need the lightest possible option for a backpacking trip? The Nocs Provisions Zoom Tube 8×32 is incredibly lightweight and has a wide field of view.
If you are on a tight budget, the Monocular Telescope High Power 8×42 Monoculars is a solid entry point. But remember, if you need two-eye comfort for long sessions, a binocular is the better tool. Check the Who Should NOT Buy section above to make sure you are getting the right optic for your needs.
FAQ
What is the best monocular overall?
The Vortex Solo Monocular 10×36 is the best overall pick. It offers the best combination of optical clarity, build quality, and a lifetime warranty at a reasonable price.
What is the difference between 8x and 10x magnification?
8x magnification makes objects appear eight times closer, while 10x makes them appear ten times closer. 8x is easier to handhold and has a wider field of view. 10x provides more detail but is harder to keep steady.
Can I use a monocular for bird watching?
Yes, a monocular is a great tool for bird watching. The 8x or 10x models are ideal for quick looks. The Gosky 12×55 is a good option if you want to take photos of birds through your phone.
Do I need a tripod for a monocular?
For magnifications of 10x and below, a tripod is optional. For 12x and above, a tripod is highly recommended to get a clear, steady image. The 80x models require a tripod for any usable viewing.
What does BAK-4 prism mean?
BAK-4 is a type of glass used in the prism of a monocular or binocular. It produces a rounder, brighter exit pupil and sharper image quality compared to the cheaper BK-7 glass. All the models in this guide use BAK-4 prisms.
Are monoculars waterproof?
Not all of them. The Vortex Solo, Adasion 12×56, and the 16×52 and 8×42 models are waterproof. The Gosky and Nocs models are not fully waterproof, so they should be kept dry.
Always check the specifications before exposing your monocular to rain.
