The Good
The Bad



Finding a good inexpensive monocular is a task that comes with its difficulties. To be of assistance to you, we have prepared a list of features that you should not overlook before placing any orders. So, read ahead and make a decision!


Lens size and magnification ratio

Monoculars usually have lenses that vary in length from 20 to 42mm. A good budget monocular usually has a lens diameter of 25mm. This is the case because products of this kind are easy to transport and use. However, units with small lenses have a limited field of view. Yet, it is worth pointing out that the devices with larger objectives are bulkier and heavier, which is why many avoid investing in them.

When it comes to the magnification ratio of a monocular, it is generally assumed that a product with a magnification ratio of 8x or 10x can cater to one’s needs. These choices are versatile as they can be used for a wide array of tasks, and they have a magnification ratio that is small enough to not affect the FOV of the model.


Size and weight

Another aspect that you should pay attention to before investing in a product of this type is the size of the unit. Generally, 10×25 and 8×25 are considered travel monoculars because they are small in size and effortless to store while on the go. Moreover, most devices of this kind often come provided with useful carrying bags that you can utilize for transportation.

The weight of the model is mainly influenced by the size of the objective lens. Usually, the bigger the lens, the heavier the unit. However, this aspect is also affected by the materials that were used in making the model.

Before you decide on a particular device, you should also consider whether or not the model that you like is weather resistant. If you are interested in quality monoculars, you should select a product that is fog and water resistant, as you will be able to use it no matter the meteorological conditions.

Plus, keep in mind that inexpensive monocular reviews recommend that one invests in a device that has been nitrogen-filled and that features O-rings for extra protection.


Extra features worth thinking about

If you are an eyeglass wearer that is looking for an affordable monocular, you should only check out devices that come fitted with adjustable eyecups. This way, you will be able to use the model without having to take off your glasses every time you decide to do so.

As a plus, before you order that unit that you’ve found for sale, be sure to verify whether or not it has a sturdy construction. In other words, the item that you select should have a sturdy housing, and it should come provided with a rubber, non-slip cover. Therefore, you will have a good grip on the device, and you won’t risk dropping it by mistake.

Additionally, your decision should always be influenced by your personal preferences. For instance, if you are interested in lightweight monoculars, you should only purchase models that have a small objective lens. However, if you need a device that you can use to observe objects that are far away, a model with a 50mm objective might be better suited.

As a plus, if you intend to utilize your new acquisition during the night, it is advisable that you restrict your search and that you start analyzing those night vision monoculars that use infrared technology.

No matter if you are looking for handheld monoculars, or for more sizeable alternatives, we are sure that, if you follow our recommendations, you will be able to select a model that can entirely cater to your needs.
