Monocular Telescope High Power 16X52: Best Budget-Friendly All-Rounder
#1
MonocularWaterproof and fogproof
8.3OUT OF 10
Optical Quality8.1
Build Quality8.5
Ease of Use8.4
Owner Verdict8.2
This is the pick for anyone who wants a genuine 16x magnification without spending a fortune. The 52mm objective lens pulls in enough light for decent low-light performance, and the nitrogen-filled body means it won’t fog up when you move from a warm car into cold air. Verified buyer reviews consistently praise the clear image at this price point.
The focus wheel is stiff but precise, which actually helps you lock onto a distant target without overshooting. It comes with a hand strap and a carrying pouch, so you can toss it in a daypack without worrying about scratches.
Flaws but not dealbreakers. The 16x magnification is powerful, but it also amplifies hand shake. You’ll want to brace your arm against a tree or use a tripod for steady viewing. Some users note the eye relief is short for glasses wearers.
If you need a more stable view at high magnification, the
Vortex Solo 10×36 further down offers a lower 10x that’s easier to hold steady.
⚠Sizing: The 16x52mm body is 6.7 inches long. It’s not pocketable, but it fits standard jacket pockets.
Pros
- ✓Waterproof and fogproof rated for all-weather use
- ✓16x magnification delivers genuine long-range reach
- ✓Rubber armor provides a secure grip in wet conditions
- ✓Includes hand strap, cleaning cloth, and carrying pouch
Cons
- ✕16x magnification is hard to hold steady without support
- ✕Eye relief is short for glasses wearers
- ✕Focus wheel can feel stiff out of the box
Field of View
195 ft @ 1000 yds
Best for: The budget-conscious buyer who needs a waterproof, fogproof monocular for general wildlife watching and hiking.
Monoculars Adults High Powered 80×100 Smartphone: Best for Smartphone Digiscoping
#2
MonocularsPhone adapter included
8.6OUT OF 10
Optical Quality8.5
Build Quality8.4
Ease of Use8.7
Owner Verdict8.8
This is the pick for anyone who wants to capture photos or videos through the lens. It comes with a smartphone adapter and a tabletop tripod right in the box, so you don’t have to buy anything else to start digiscoping. The BAK-4 prism and fully multi-coated (FMC) lenses deliver a bright, crisp image that translates well to phone photos.
The 80×100 specification sounds huge, but it’s important to understand this is a variable zoom monocular. The 80x is the maximum zoom, which is useful for stationary targets like a bird’s nest. The included tripod is essential at that magnification level.
Flaws but not dealbreakers. The high zoom produces a narrow field of view, making it hard to locate moving animals. The included tripod is lightweight and works best on a table rather than in the field.
If you want a more portable option for hiking, the
Monocular 16X52 above is lighter and easier to carry on a trail.
⚠Compatibility: The smartphone adapter fits most phones, but very large camera bumps may require a specific alignment.
Pros
- ✓BAK-4 prism and FMC lenses for bright, clear images
- ✓Smartphone adapter and tripod included in the box
- ✓Variable zoom from low to 80x magnification
- ✓Rated 4.6/5 from verified buyers
Cons
- ✕High zoom needs a tripod for steady viewing
- ✕Narrow field of view at 80x makes target acquisition tricky
- ✕Included tripod is lightweight, not for rugged terrain
Magnification
Variable up to 80x
Best for: Birders and photographers who want to capture sharp images through their phone without extra gear.

8.0OUT OF 10
Optical Quality7.8
Build Quality7.9
Ease of Use8.1
Owner Verdict8.2
This is the budget-friendly entry point to the 80×100 category. It offers the same variable zoom and smartphone adapter setup as the higher-rated models, but at a lower price point. The green rubber armor helps it blend into natural surroundings, and the lens cap is tethered so you won’t lose it.
Aggregate user reviews highlight the value for money. The image quality is good for the price, though it doesn’t match the BAK-4 prism clarity of the more expensive picks. The focus ring is smooth, and the zoom lever works well for gradual adjustments.
Flaws but not dealbreakers. Some users report slight chromatic aberration (color fringing) around bright objects at maximum zoom. The tripod included is a basic mini tabletop model, not a full-size field tripod.
⚠Care: The zoom mechanism is internal; avoid forcing it past the stop point to prevent damage.
Pros
- ✓Very affordable entry into 80×100 zoom monoculars
- ✓Includes smartphone adapter and mini tripod
- ✓Green rubber armor for camouflage and grip
- ✓Decent image quality for the price point
Cons
- ✕Some color fringing at maximum zoom
- ✕Included tripod is too small for field use
- ✕Not fully waterproof like some competitors
Magnification
Variable up to 80x
Best for: The budget buyer who wants a high-magnification zoom monocular with a smartphone adapter for casual use.

7.9OUT OF 10
Optical Quality8.0
Build Quality8.2
Ease of Use7.8
Owner Verdict7.6
This is the pick for buyers who want a nitrogen-filled monocular that resists internal fogging in changing weather. The 40×60 specification is a fixed 40x magnification with a 60mm objective lens. It uses BAK-4 prisms and fully multi-coated lenses, which deliver a noticeably brighter image than budget BK-7 prism models. The nitrogen purge means it won’t fog up when you bring it inside from the cold.
The package includes a smartphone holder and a small tripod, so you can set up for digiscoping right away. The twist-up eyecup is adjustable, which helps glasses wearers get a full field of view. The focus knob is centrally located and easy to operate with gloves on.
Flaws but not dealbreakers. The 40x magnification is fixed, not variable, so you can’t zoom in or out. Some users mention the tripod is a bit flimsy for the weight of the monocular plus a phone.
⚠Sizing: The 60mm objective lens makes this a bit larger than pocket-sized. It’s best for a jacket or backpack.
Pros
- ✓Nitrogen-filled for fogproof performance in all weather
- ✓BAK-4 prism for brighter, sharper images
- ✓Includes smartphone adapter and mini tripod
- ✓Twist-up eyecup is good for glasses wearers
Cons
- ✕Fixed 40x magnification, no zoom
- ✕Included tripod is a bit flimsy for digiscoping
- ✕Larger size than expected for the magnification
Waterproof
Nitrogen-filled
Best for: The outdoors enthusiast who needs a fogproof, high-contrast monocular for wet or cold conditions.
TOPDON TS004 Thermal Imaging Monocular: Best for Night Hunting & Search
#5
TOPDONThermal, 256×192 IR
8.5OUT OF 10
Optical Quality8.4
Build Quality8.7
Ease of Use8.2
Owner Verdict8.6
This is the pick for anyone who needs to see in total darkness, through smoke, or in heavy brush. The TOPDON TS004 uses a thermal imaging sensor with a 256×192 infrared resolution. It detects heat signatures up to several hundred meters away, making it ideal for hunting hogs at night, search and rescue, and security patrols. The 50Hz refresh rate means the image is smooth, not choppy, which is crucial when tracking moving animals.
The housing is rated IP67, meaning it’s dust-tight and can be submerged in 1 meter of water for 30 minutes. The battery life is rated at 11 hours, which is excellent for a full night in the field. It also supports wireless connection to a smartphone app for live streaming or recording.
Flaws but not dealbreakers. Thermal monoculars cannot show color or detail like a traditional optical monocular. You see heat signatures, not actual shapes. This is a specialty tool, not a replacement for a regular monocular.
If you need a traditional optical monocular for daytime use, the
Vortex Solo 10×36 further down offers superior clarity for daylight scouting.
⚠Regulations: Thermal imaging devices are legal for hunting in most states, but check local wildlife regulations before using in the field.
Pros
- ✓256×192 thermal sensor detects heat up to several hundred meters
- ✓50Hz refresh rate for smooth tracking of moving targets
- ✓IP67 waterproof and dustproof rating
- ✓11-hour battery life for all-night missions
Cons
- ✕Cannot identify color or fine details, only heat signatures
- ✕Premium price point compared to standard monoculars
- ✕Requires some practice to interpret thermal images
Best for: Night hunters, security personnel, and search-and-rescue teams who need to detect heat signatures in total darkness.
Monocular Telescope High Power 8×42 Monoculars: Best for Hikers & Kids
#6
MonocularLightweight, 8x
8.2OUT OF 10
Optical Quality8.0
Build Quality8.3
Ease of Use8.5
Owner Verdict8.1
This is the pick for hikers, kids, and anyone who wants an ultra-light monocular that’s easy to carry all day. The 8×42 configuration is a classic all-around choice. 8x magnification is low enough to hold steady by hand, and the 42mm objective lens provides a bright, wide field of view. It’s a fantastic first monocular for a child or a lightweight option for trail runners.
The body is waterproof, fogproof, and shockproof with a rubber armor coating. It weighs very little, so you won’t notice it in your pocket or pack. The focus wheel is smooth and easy to turn with one hand.
Flaws but not dealbreakers. 8x magnification is not enough for long-range viewing of distant wildlife. If you’re trying to identify a bird on the far side of a lake, you’ll want more power. The lens caps are not tethered, so they can get lost.
If you need more reach for long-distance viewing, the
Monocular 16X52 at the top of this list offers double the magnification.
⚠Sizing: This is a compact monocular that fits easily in a coat pocket or small pouch.
Pros
- ✓Very lightweight and compact for all-day carry
- ✓8x magnification is easy to hold steady
- ✓Waterproof, fogproof, and shockproof
- ✓Wide field of view for scanning and tracking
Cons
- ✕8x magnification is too low for long-distance wildlife
- ✕Lens caps are not tethered to the body
- ✕Not as bright as larger 50mm+ objective lenses
Field of View
393 ft @ 1000 yds
Best for: Hikers, families, and kids who need a lightweight, easy-to-use monocular for general outdoor exploration.

Owner Verdict7.9
This is the budget alternative for anyone who wants the 80×100 zoom experience at the lowest possible cost. It’s very similar to the green model above, but in a black finish. It includes a smartphone adapter and a mini tripod, so you can start taking photos right away. The zoom lever is easy to operate, and the focus ring is smooth.
Aggregate user reviews show that it’s a good value for the price. The image is clear enough for casual bird watching and moon viewing. The body is made of a durable plastic composite with a rubberized coating for grip.
Flaws but not dealbreakers. The image quality is not as sharp as the BAK-4 prism models, especially at the edges of the field. The tripod is very basic and not suitable for uneven ground. Some users report that the zoom ring can be a bit stiff initially.
⚠Care: The zoom mechanism is internal; avoid forcing it past the stop point to prevent damage.
Pros
- ✓Lowest price point for an 80×100 zoom monocular
- ✓Includes smartphone adapter and mini tripod
- ✓Variable zoom for flexibility
- ✓Rubberized coating for a secure grip
Cons
- ✕Image quality is not as sharp as BAK-4 models

Vortex Solo Monocular 10×36: Best Premium Build & Warranty

VortexLifetime warranty
8.7OUT OF 10
Optical Quality8.9
Build Quality9.0
Ease of Use8.6
Owner Verdict8.4
This is the pick for buyers who value optical clarity and a lifetime warranty above all else. The Vortex Solo 10×36 is a premium monocular from a brand known for its rugged, high-performance optics. The 10x magnification is a sweet spot for long-range viewing without being too hard to hold steady. The 36mm objective lens is smaller than some, but the multi-coated lenses deliver a bright, crisp image even in low light.
The body is rubber-armored, waterproof, and fogproof. The adjustable eyecup twists up for glasses wearers and down for non-glasses wearers. The real selling point is the VIP warranty: Vortex will repair or replace it for any reason, no questions asked, for life. This is the best warranty in the industry.
Flaws but not dealbreakers. The 36mm objective lens is smaller than the 42mm or 52mm options on this list, so it’s not as bright in very low light. It also doesn’t include a smartphone adapter or tripod, so you’ll need to buy those separately if you want to take photos.
If you need a brighter image for low-light conditions, the
Monocular 16X52 at the top of this list has a larger 52mm objective lens.
⚠Warranty: The Vortex VIP warranty is unconditional and transferable , covering any damage or defect for the lifetime of the original owner. It’s the best peace of mind you can get in optics.
Pros
- ✓VIP lifetime unconditional warranty, transferable
- ✓Multi-coated lenses for bright, sharp images
- ✓Waterproof, fogproof, and rubber-armored
- ✓Lightweight and compact at just 7.5 oz
Cons
- ✕36mm objective is less bright in low light than larger lenses
- ✕No smartphone adapter or tripod included
- ✕Premium price point compared to similar specs
Field of View
305 ft @ 1000 yds
Best for: The discerning buyer who wants a lifetime warranty and top-tier optical performance in a compact package.
Buying Guide: Magnification, Lens Size, Prism Type and What You'll Use It For
Picking a long-range monocular is simpler than it looks if you focus on four things. Here's what matters.
How much magnification do you actually need?
This is the biggest trap. More magnification is not always better. The 16x52mm model at the top is a great example. 16x lets you see a deer across a field, but it also magnifies every tiny shake in your hands.
You'll need to brace against a tree or sit down to get a steady view.
Lower magnification like 8x or 10x is much easier to hold steady. The 8×42 and the 10×36 Vortex are both excellent for handheld use. If you plan to shoot photos, high zoom like 80x is fun for stationary targets, but you absolutely need a tripod.
Objective lens size: bigger is brighter, but heavier
The number after the "x" is the objective lens diameter in millimeters. A 52mm lens lets in more light than a 36mm lens. That means brighter images at dawn and dusk.
The tradeoff is size and weight. The 80×100 models have a massive 100mm objective, which is great for light but makes the monocular bulky. The 8×42 is a good middle ground for hikers who want brightness without the bulk.
BAK-4 vs BK-7 prisms: what's the difference?
Prism type affects image sharpness. BAK-4 prisms are made from higher-quality glass and produce a rounder, brighter exit pupil. BK-7 is cheaper and can produce a slightly clipped or dimmer image at the edges.
The Monoculars 80×100 Smartphone uses BAK-4, which is why it scores higher on optical quality than the budget 80×100 models that use BK-7. If you care about sharpness, spend the extra for BAK-4.
Waterproofing and fogproofing: do you need it?
If you'll be out in rain, snow, or high humidity, get a nitrogen-filled model. The 16X52 and the 40X60 are both nitrogen-purged, meaning they won't fog up internally. The Vortex is also fully sealed.
The budget 80×100 models are not fully waterproof, so they're best for fair-weather use.
To see how these factors play out on real picks, compare the Monocular Telescope High Power 16X52, Monoculars Adults High Powered 80×100 Smartphone and the Monocular-Telescope 80×100 High Powered Monoculars reviewed above.
Who Should NOT Buy Best Long-range Monocular
A standard monocular is the wrong purchase for a few kinds of buyers. Here's who they are, and what to look at instead.
You Need to See in Total Darkness
If your primary use is hunting hogs at midnight or searching for missing persons in the dark, a standard optical monocular is useless. You need a thermal imaging device like the TOPDON TS004 in this list, or a dedicated night vision scope. A standard monocular relies on ambient light, which doesn't exist at night.
You Want a True Telescope for Astronomy
A monocular is not a telescope. It's a handheld device for terrestrial viewing. If you want to look at Saturn's rings or the craters on the moon in detail, you need a real telescope on a tripod.
A monocular can show you the moon's general shape, but it won't give you the magnification or stability for serious astronomy.
You Need Binoculars for Depth Perception
For tracking fast-moving birds or following a running animal, a monocular gives you only one eye. That means you lose depth perception. If you're trying to follow a bird in flight, binoculars are much easier to use.
The linked guide to steady viewing for shaky hands can help you choose the right binoculars if that's your need.
Final Verdict
The best long-range monocular for most people is the Monocular Telescope High Power 16X52. It gives you a genuine 16x magnification, a waterproof and fogproof build, and a price that's fair for the quality. It's the all-around workhorse that will serve you well for years.
Want to digiscope with your phone? Get the Monoculars Adults High Powered 80×100 Smartphone. It's the only one here that includes a BAK-4 prism, a phone adapter, and a tripod right out of the box.
Need a compact, lightweight option for hiking? The 8×42 Monocular is your best bet. It's small, tough, and easy to use.
And if you want the absolute best build quality and a lifetime warranty, the Vortex Solo 10×36 is the one to buy. It's an investment, but it's the last monocular you'll ever need.
If you're still not sure, read the Who Should NOT Buy section again. It's just as important to know what not to buy as it is to know what to buy.
FAQ
What's the best long-range monocular overall?
The Monocular Telescope High Power 16X52 is the best overall. It balances 16x magnification, waterproofing, and a reasonable price in a way that no other model here does.
Can I use a monocular with my phone?
Yes, but only if it comes with a smartphone adapter. The Monoculars Adults High Powered 80×100 Smartphone and the 40X60 Monocular both include adapters. The Vortex and the 16X52 do not, so you'd need to buy an adapter separately.
What's the difference between 8×42 and 16×52?
The first number is magnification. 8x makes objects look 8 times closer, while 16x makes them look 16 times closer. The second number is the objective lens diameter in millimeters. A larger lens lets in more light, which is important in low light. 16x is harder to hold steady than 8x.
Is a monocular better than binoculars?
It depends. A monocular is lighter, smaller, and cheaper. Binoculars give you depth perception and are easier to use for tracking moving subjects.
If you're hiking and want to save weight, get a monocular. If you're birding or hunting, binoculars are usually better.
Do I need a tripod for a high-power monocular?
Yes, for anything above 12x magnification. The 16×52 and the 80×100 models are very hard to hold steady by hand. A tripod or a firm rest will make a huge difference in image quality.
What is the VIP warranty on Vortex?
The Vortex VIP warranty is an unconditional lifetime warranty. It covers any damage or defect, no questions asked, for the life of the original owner. It's fully transferable if you sell the monocular.
That's the best warranty in the optics industry.
