The RainGuard HD coating is effective at
Gosky 12×55 High Power Prism Monocular
If you’re looking for high magnification on a budget, the Gosky 12×55 is a strong contender. The 12x power brings distant objects remarkably close, and the large 55mm objective lens is key for gathering light, making it effective during dawn or dusk. I’ve used it for stargazing and was pleasantly surprised by the views of the moon and brighter star clusters. The BAK4 prism and fully multi-coated lenses work together to provide a clear, high-contrast image that punches above its price point. It also includes a smartphone adapter, which is a fun bonus for trying your hand at digiscoping.
The build quality feels solid for the cost, with a rubberized body that’s comfortable to hold. It comes with a tripod adapter, which I highly recommend using for anything beyond brief observations at 12x magnification, as it significantly stabilizes the view. The focus wheel is smooth and allows for precise adjustments. While the field of view is naturally narrower due to the high power, it’s perfectly adequate for its intended purpose. This monocular represents excellent value for someone who wants powerful magnification without a huge investment.
Pros

Like the Zeiss, it offers impeccable build quality and stunning image quality in a minuscule form factor. The view is crisp, with true-to-life colors and excellent contrast. But the Monovid has a unique trick up its sleeve: a built-in close-focus lens that flips down, allowing you to focus on objects as close as 6.5 feet. This macro function is surprisingly useful for looking at insects, flowers, or even checking the fine print on a map.
Using the Monovid is a pleasure. The mechanics are smooth and precise, and it feels like a precision instrument. It’s also waterproof and comes with a high-quality leather pouch. This is undoubtedly a luxury item, but for the discerning user who appreciates the finest craftsmanship and versatile functionality, it’s in a class by itself. It’s the kind of tool you buy once and cherish for a lifetime.
Pros

Buying Guide: 10 Best Monocular Telescopes for Long-Range Viewing | 2025
Choosing the right monocular for long-range viewing can feel tricky with so many options out there. I have tested a lot of them, and I can tell you that focusing on a few key specs makes the decision much easier. It is not just about how far you can see, but how clearly and comfortably you can see it.
First, consider the magnification and objective lens size. You will see these numbers written as something like 12×50. The first number (12x) is the magnification. For long distances, I usually look for something between 10x and 15x. Anything higher can be very difficult to hold steady without a tripod. The second number (50) is the diameter of the front lens in millimeters. A larger lens gathers more light, which means a brighter and clearer image, especially in low-light conditions like at dawn or dusk. A 50mm lens is a great balance between power and portability.
Next, pay close attention to the lens quality. Look for terms like fully multi-coated or ED (Extra-low Dispersion) glass. Multi-coatings reduce glare and reflections, giving you better color fidelity and contrast. ED glass is a step up; it significantly reduces chromatic aberration, which is that annoying color fringing you sometimes see around high-contrast edges. If you want the sharpest possible image, ED glass is worth the investment.
Build quality is another big one. A monocular for long-range viewing should feel solid in your hand. I prefer models with a rubber armored body because it provides a secure grip and protects the device from minor bumps and shocks. Weatherproofing is also crucial. Look for features like nitrogen purging and O-ring seals to prevent internal fogging and keep moisture and dust out. This means you can use your monocular in rain or high humidity without worry.
Finally, think about the extra features that improve usability. Image stabilization is a game-changer for high-magnification models, but it adds to the cost and requires batteries. A tripod adapter is a must-have if you plan on prolonged viewing sessions. Some monoculars even have smartphone adapters, which is a fun way to capture what you are seeing. By weighing these factors—magnification, lens quality, durability, and features—you will be well on your way to finding the perfect monocular for your needs.
FAQ
What is the ideal magnification for a long-range monocular?
For most situations, a magnification between 10x and 12x is the sweet spot. It provides a significant zoom for long-range viewing while still being manageable to hold by hand without excessive shaking. If you go for 15x or higher, I strongly recommend using a tripod for a stable view. Higher magnification also narrows your field of view, making it harder to locate and track objects.
How important is the size of the objective lens?
It is very important. The objective lens is the main light-gathering component. A larger lens (e.g., 42mm or 50mm) allows more light to enter, resulting in a brighter image. This is critical for viewing in low-light conditions, such as at sunset or in a dense forest. However, a larger lens also means a larger and heavier monocular, so you have to balance brightness with portability.
Can I use a monocular with eyeglasses?
Yes, absolutely. Many modern monoculars are designed with eyeglass users in mind. Look for models that have long eye relief—typically 15mm or more. This is the distance your eye can be from the eyepiece while still seeing the entire field of view. Just make sure to twist down the rubber eyecup if your monocular has one, which will give you the extra space needed.
What does “waterproof” really mean for a monocular?
In this context, waterproof usually means the monocular is O-ring sealed and filled with nitrogen or argon gas. This prevents moisture from getting inside and also stops internal fogging when you move between different temperatures. It does not typically mean you can submerge it deeply for long periods. Check the manufacturer’s specifications for a specific IPX rating, which will tell you its exact level of water resistance.
Are more expensive monoculars always better?
Not always, but you are generally paying for better optical quality and construction. Inexpensive monoculars can be decent for casual use, but they often have weaker coatings, more image distortion, and less durable bodies. If you are serious about long-range viewing, investing in a mid-range or high-end model with features like ED glass and robust weatherproofing will provide a noticeably sharper, brighter, and more reliable experience. This is a key consideration when looking at the 10 Best Monocular Telescopes for Long-Range Viewing | 2025.
What is the advantage of a monocular over binoculars?
The main advantage is size and weight. A monocular is about half the size and weight of a comparable pair of binoculars, making it much easier to carry in a pocket or small bag. This makes it perfect for hiking, birdwatching, or sporting events where you want to travel light. You also have the benefit of keeping one eye on your surroundings, which can be safer in certain situations.
