Good hunting binoculars are indispensable for hunters during hunting and are an important companion. When choosing a pair of binoculars you should always look for quality so that you can enjoy your hunting binoculars for many years to come. Not every hunting binocular is suitable for every type of hunting and you should consider the most important characteristics of a pair of binoculars when making your choice.
In this guide we give you an overview of the following criteria that you should consider when buying:

  • the two most important key figures
  • hunting species at a glance
  • twilight factor
  • coating or light transmission
  • robustness and weight
  • the BRESSER guarantee




Magnification factor
When hunting, it is often important to be able to address the game well at long distances. For this reason, one quickly tends to focus on binoculars with high magnification. However, this can be a fallacy. Hunting binoculars with high magnification are quite suitable for the field. In the forest, the field of view is quickly restricted by the higher magnification. It is also important to know that high magnifications always result in a loss of light. A 10x56 hunting binoculars can therefore not produce such a bright image as an 8x56 with the same quality. It can therefore be helpful to dispense with a higher magnification and thus take advantage of the brightness and field of view. This is particularly noticeable at twilight and can lead to a necessary advantage. It should also be remembered that the higher the magnification, the more unsteady the image becomes. So, an 8x binocular is quieter to hold in your hand than a 10x. In today's world where thermal imaging plays an increasingly important role, one should weigh up the advantages and disadvantages more carefully. As you switch to thermal imaging in twilight and at night, 8x42 or 10x42 binoculars can be a real alternative to large, heavy 56 hunting binoculars during the day.

Lens diameter
The second number indicates the lens diameter in mm. A 7x50 prism binocular has a lens diameter of 50 mm. This is an important performance feature, because the larger the lens diameter, the greater the incidence of light and therefore the brighter the image. A diameter of 21 mm (8x21) is sufficient for daytime observations. However, if observations have to be made during twilight, the binoculars should have a diameter of at least 50 mm.


Different types of hunting require different characteristics of the binoculars. What types of hunting are there and how should the binoculars be designed for the different types of hunting? Here we give a brief overview of the different types of hunting and which binocular characteristics are advantageous in each case.

Stalking hunt
In this type of hunting the hunter moves slowly and carefully through the woods to watch the game. In order for the hunter to discover or kill the game unseen, the hunting binoculars should be light and robust. A low magnification of about 8x is recommended. This way the hunting binoculars still fit well in the hand and offer ideal observation. A maximum lens diameter of 42 mm is optimal so that the hunting binoculars do not become too heavy.

Hunting from a raised hide
When hiding, the game is usually observed for several hours until dusk. The hunting binoculars should therefore have a magnification of at least 8x and an objective lens diameter of at least 50x. A higher weight will also prevent the image from "shaking". If the hunting binoculars become too heavy in the long run, you can use a tripod.

Driven hunt
The driven hunt is a moving hunt with several hunters. The hunters slowly drive the game from cover and get it moving. The hunter can then kill the game safely and gently. Because of the active and fast movement, the hunting binoculars must be robust and easy to handle. A magnification of maximum 8x and a lens diameter of maximum 42 mm are a good choice here.

Most of the time, these are animals that can only be observed at dusk and at this time of day the lighting conditions are not ideal for observations with the naked eye. This is why hunting binoculars need to be all the brighter so that details can be seen even at dusk in the morning or evening hours. Binoculars should already have a magnification of 7x and a corresponding objective lens diameter of at least 50 mm to do justice to this twilight performance. The power to make observations at twilight is indicated in the twilight index. This is a standardised value for comparing optical devices with regard to detail recognition, especially in poor lighting conditions.

The higher the twilight factor, the more light the device theoretically emits. However, the twilight factor does not say much about the quality of hunting binoculars. For example, a pair of binoculars for €2000 has the same twilight factor as a pair for €200. This parameter can therefore only be used as a nominal value for the same binocular series.The twilight factor is calculated from the square root of the product of magnification and lens diameter. So for a 7x50 hunting binocular: (square root of magnification x objective diameter).
e.g: square root of 7x50 = 18,71

Twilight factor - hunting binoculars


A major factor in the imaging of hunting binoculars, however, is that as little light as possible is lost along the path of the lens aperture all the way to the eye. For this reason, additional coatings are used at higher quality levels, which transport the light even better. This is where BRESSER uses the UR coating or Ultimate Reflection coating. Hunting binoculars like the Pirsch ED even have a Dielectric coating, which transports the light even better to the eye. This further increases the light transmission of the lenses.

A further coating is used for contrast. This is often referred to as phase coating. This is a special coating on the roof prism. When the light hits the roof prism, it is reflected several times in the shape of a roof edge. In addition, the reflection splits the beam into two segments. This procedure causes a shift in the phases of the light waves. The waves of the light rays are not equal, but shifted. This would minimize the resolution and also the contrast. However, to prevent this, special layers are applied to correct this phenomenon.

Light transmission - hunting binoculars


When hunting, you are often in rough terrain. Therefore it is important to have robust hunting binoculars as a companion. Several factors play a role. Firstly, hunting binoculars should be waterproof and filled with nitrogen. So even a rain shower or fog cannot damage the binoculars. Also, the nitrogen or argon filling prevents the binoculars from fogging from the inside. So the binoculars are always ready for use.
Furthermore, the important components such as eyepieces and focusing should be very robust. BRESSER's hunting binoculars all feature metal twist-up eyecups and metal focusing. The stalking and stalking EDs still offer metal bridges, which fully round off the concept. A rubber armouring offers further protection. This should not be too thin to provide enough protection against light impacts.

the weight of a hunting binocular depends strongly on its use. A lightweight hunting binocular is ideal for transport and for use during active hunting. A heavy binocular > strong> on the other hand has the advantage that it is easier to hold in the hand and the image does not start to "tremble". If the binoculars become too heavy, you can also use a tripod when sitting upright.


The guarantee is another important factor. Because despite all precautions a hunting binocular may fall from a high seat. So make sure you have a sufficient guarantee. Many manufacturers offer a longer warranty period than 2 years. BRESSER even offer a premium warranty free of charge for the hunting binoculars Condor, Pirsch and Pirsch ED. This covers all damages which can occur during normal use. Your binoculars will be repaired free of charge if they fall from a high seat, for example. You can find more about this guarantee at
