Choosing binoculars, especially the first one, is not an easy task. The enormity of available models, sizes, shapes, and magnifications can make the proverbial head spin. On top of that, browsing through different types of optics, we may come across monoculars and spotting scopes which will add further options to our purchase considerations. And that’s what this entry will be about. How to guide ourselves with the plethora of models and choose for ourselves a binocular that will perfectly fit our needs?

For more information on selecting sight look at this site.


Let’s start with the technical specifications and types of binoculars you may come across in our store.


The magnification of binoculars is described in a similar way as in spotting scopes – 7×50, 15×70, 10-22×50.

The first number before the “x” describes to us the magnification parameter (its multiplicity or so-called “zoom”). According to the above examples, the 7×50 model will magnify the image seven times, the 15×70 will magnify it 15 times, and the 10-22×50 model has an adjustable zoom, which we can smoothly adjust between 10 and 22.

The next number after the “x” is the size of the lenses, described in millimeters. Thus, the 7×50 has lens sizes of 50mm, the 15×70 is 70mm and the 10-22×50 is 50mm.

Well, yes, it’s best to choose the binoculars with the highest magnification.

On the contrary, as the zoom increases, less light enters our eye, and the image is of poorer quality, darker, and distorted. In addition, at zooms greater than 10x, the handshake becomes more pronounced. The width of the viewing angle also decreases as the zoom increases. The higher the zoom parameters, the smaller the slice of terrain we see.

It is also worth mentioning that all the models we offer have glass optics – even the cheapest ones.

The type of prism used

With the choice of the prism used in binoculars, the shape, weight, and dimension of the binoculars change.

Porro prism binoculars – porro is named after Ignazio Porro, an Italian artillery officer who invented the system around 1850. The porro prism system was the first to be used in binoculars. It consists of two isosceles triangles that rotate the image seen through the binocular lens by 180 degrees, and then send it to the lenses and onto our eyes.

The porro system is used in classic models of binoculars from many manufacturers. The way the prisms are arranged does not allow for a compact design, but due to the small number of additional optical elements, they let almost 100% of the light through. For this reason, classic binoculars are suitable for night observation and in low-light conditions. Porro binoculars work best wherever a small amount of sunlight reaches, there is cloudy or rainy weather, or it is simply dark.

Binoculars in the roof system – the name of this system come from the English word “roof”. It describes the shape of the prisms found in binoculars of this type. Roof system binoculars have a much more compact internal structure, making their dimensions much smaller. Such binoculars are also generally lighter than their conventional counterparts. By design, roof binoculars have a much more complex structure, and their optical components must be of high quality. For this reason, these binoculars are relatively more expensive than their classic counterparts. Light losses in roof prisms are also higher than in porro prisms, so the roof design is more suitable for daytime observation. These models will work well for hiking, boating, and anywhere where the small size and weight of transported equipment are important.

Tourist binoculars

The most popular binoculars on our offer are typically tourist models. They have a magnification of seven times or up to ten times. Combined with 50mm eyepieces, we get binoculars with a very bright image, in which handshaking is very hardly visible. Also, the slice of the observable area is very wide. Such binoculars are ideal for use in the mountains, on trails, or during trips to the park.

The most popular models are optics from the Delta Voyager and Delta Entry series. Recently, models from the COMET series are also popular, and for more demanding travelers I recommend a higher-end product from the Delta Forest II quality range. Hikers who want to save space in their gear choose models with smaller lenses than the standard 50mm: Delta Voyager 10×25, or Celestron 8×40.

Astronomical binoculars

Binoculars with larger objective lenses and considerable magnification are very often sought after by our customers. These binoculars are most often used as optics for night sky observation. Thanks to x15 or x25 magnification and special MC coatings, we will see much more detail in the night sky than with the naked eye. These binoculars are also suitable for observing aircraft and land objects in low-light conditions. Due to the increased weight and high magnification, we recommend using a tripod.

The most popular models are products of the Celestron SkyMaster series.

Hunting binoculars

This is a group of more expensive products, designed and manufactured with exceptional attention to light transmission. These binoculars are mostly used in very low light conditions and at relatively short distances. Low magnifications, together with the filters and MC coatings used, will give us a bright and clear image. Hunting binoculars are also additionally filled with dry nitrogen, which protects them from moisture, rain, fog, or dew. The best examples are the Delta Titanium series and Vortex Vulture binoculars.


Choosing the perfect pair of binoculars is not easy, especially because of the vast number of models available on the market. I hope the above post has clarified the basics and the types of optics you can buy. Now you can confidently buy the right model that is right for you.
