The Good
The Bad



If you are determined to purchase a good monocular under 150, there are a couple of features that you should have in mind before you place an order. To be of help, we have prepared a list of crucial aspects that you should not neglect.


The power and the size of the lens

First things first, the specialists argue that you have to pay attention to the magnification power of the device. The magnification of a monocular is the number that lets you know just how much larger will a given image be depicted. To put it in simple terms, the higher the magnification, the closer you will be able to see a particular object. However, units that have a large magnification but a small objective should be avoided as they have a small field of view.

Furthermore, quality monoculars have great lenses. The diameter of the lens, or of the objective influences the clarity of the images that you are provided with. A unit that has a large lens will be able to gather more light and thus, will provide the user with bright and clear images. However, keep in mind that, the larger the lens, the heavier the monocular.


Lens coating and prism type

Generally, the lenses that most handheld monoculars have are made from glass that may refract some of the light. As a result, the user will be supplied with slightly darker images. To mend this problem, most manufacturers coat the lenses so that the light transmission is increased.

Because of this, most reviews of monoculars under 150 recommend that all interest buyers purchase items that have fully multi-coated objectives. Still, you should know that these units are usually rather expensive when compared to those devices that have only been coated with a single protective layer.

What is more, the type of prism that a unit has is also quite important. Because of this, before you order that unit that you’ve found for sale, it is critical that you spend some minutes assessing your alternatives.

From this point of view, you can choose from models with Porro prisms, roof prisms or Galilean prisms. Most units out there come provided with a Porro prism design. However, it is a known fact that the devices with a roof prism may offer a higher-quality image.


Extra tips and tricks

No matter if you want to buy travel monoculars or a more sizeable option that can be used for wildlife observation, it is also crucial that you examine a few extra features. For instance, you should take the time to check the exit pupil size of each model that you like.

The exit pupil size is the actual ratio between the power of magnification and the diameter of the lens, and it determines the amount of light transmitted to the eye. Hence, the bigger the exit pupil size, the better the light transmission will be.

Another crucial element that you should think about is the FOV of a product. The field of view is the width of the area seen when standing 1000 yards away from the object that is being observed. The FOV is greatly influenced by the magnification power of a monocular. Consequently, a model with high magnification will have a narrower FOV.

The focusing mechanism that the product that you like has should also be analyzed. For best results, you should invest in a device that is easy to focus by using a single hand. Plus, if you want your budget monoculars to last, it is important that you select a product that was made using high-quality materials like metal or sturdy plastic.

If you do not have a lot of experience when it comes to shopping in this line of products, we recommend that you read this buying guide on how to pick a monocular for hunting. Additionally, this article on how to select a quality monocular for bird watching might also help.
