Marine binoculars are an optical device in which all parameters are oriented towards operation in extreme conditions: constant vibration, pitching, increased humidity levels, the danger of direct contact of water with the optics or even drowning of the binoculars, the need for use at night and in poor visibility.
Binoculars help solve the problem of the scale of the panorama; most models allow you to cover the entire water surface to the horizon with your eye. Using marine binoculars, you can also carry out specific measurements – calculate coordinates.
Based on these tasks, we can highlight the key characteristics of marine binoculars that you should pay attention to when purchasing:
- very high aperture values so that the optics allow observations in bad weather and twilight;
- ultra-wide field of view;
- low magnification to prevent narrowing of the field of view and reduce sensitivity to motion;
- protection from water, wind and other negative external factors.
This obliges manufacturers and users to seek the optimal balance of indicators, which has led to the production of various types of this useful optical device.
Types of Binoculars
Types of marine binoculars are classified into different categories, one of which is the prism system type. Despite the fact that the appearance of marine binoculars has not changed much since the time of its designer Galileo, modern models practically do not use the basic Galilean optics system.
Instead, complex prism systems are installed – Porro or Roof. Until recently, the first type was more often seen – large binoculars with a characteristic angle to the sides, which were strongly associated with the attributes of sea wolves and sea captains.
Nowadays they produce modern, high-tech Roof models – they are not inferior in clarity to Porro prisms, but are less bulky and heavy. Perfect prismatic systems allow achieving high image quality at magnifications from 7x to 15x. These are standard parameters for marine optics, although there are variations with a magnification of 25x.
Depending on the distinctive features of marine binoculars, they can be divided into the following types, with characteristic key parameters.
- Fixed magnification. The fixed magnification range is typically 7x to 10x. Provides stable and clear images without the need for adjustments.
- Zoom technology provides variable magnification that can be useful in different viewing conditions. Additional adjustments may be required to achieve a clear image.
- Image stabilization. The model is equipped with a stabilization system to compensate for movements of the boat or hands. Provides stable images even at high magnification.
- Adjustable focal length. Allows you to quickly adjust the distance between the eyepiece and the human eye, provided that the position of the object being viewed changes. A particularly useful feature when observing fast-moving objects.
- Phase correction. The prisms of this type of model have a special coating that improves image clarity, contrast and color rendition. Provides higher image quality, especially in difficult lighting conditions.
- High light transmission. This type of marine binoculars is designed for use in low light conditions, such as dawn or dusk. Provides bright and clear images even in low light conditions.
- Built-in compass. Allows users to determine the direction of an object in their field of view. They are often backlit for use at night.

FAQ
What are the features of marine binoculars?
Water resistance is a critical feature of all types of marine binoculars. Protection from moisture is necessary not only in rainy weather, but also for using binoculars in conditions of high humidity. Binoculars with a waterproof housing and nitrogen filling prevent fogging of the optics from the inside, which is especially important during sudden temperature changes. This makes them an ideal choice for sailors, hunters, hikers and nature lovers who spend time in challenging weather conditions.
The impact resistance of the binoculars is ensured through the use of durable case materials and internal shock absorption of the optical elements. This is extremely important for active users who are forced to expose their equipment to vibrations or shocks, for example, during rolling.
A selection of marine binoculars with high impact resistance is available on the topRik marketplace, which will help avoid damage to the optics and extend the life of the device. Manufacturers use a new wave-like texture of the rubber coating of the body, which significantly improves the grip of the binoculars and ease of handling. In addition, the texture has special water-repellent properties that guarantee non-slip and safe handling even in rough seas. It is no coincidence that the warranty period for Navigator binoculars reaches 10 years.
But the benefits of this rugged case don't stop there. It is also an anti-corrosion coating, since this marine plastic is not only an excellent sealant, but also does not oxidize.
If we talk about the functional characteristics of marine binoculars, then we should highlight their high light transmittance. Light transmittance is the amount of light that passes through all binocular lenses without loss. This parameter depends on the quantity and quality of light-refracting elements, the presence of an antireflective coating on them and the quality of assembly. The higher this ratio, the brighter the image will be. For top models of binoculars it can reach 97%. Light transmittance values of 94% and above are considered acceptable.
Which binoculars are suitable for long swimming, fishing or walking on a lake?
Many people mistakenly believe that the higher the magnification, the better. In fact, this is not true. Which magnification to choose depends on the purpose of the device. Let's take a closer look at which binocular magnification is better.
The maximum number of powers is only good for astronomical binoculars used on a tripod. Cool device magnifies 50 times or more. Already at a magnification of more than 10, it becomes difficult to observe with your hands – you need at least a support for them, otherwise the image shakes a lot.
For hunting, it is better to choose compact models with a magnification of 7-10x for examining objects at close distances.
The field magnification should be 8–20 and have a tripod mount. It is used for medium and long range surveillance.
For the military, the optimal value is 7–10. This is due to the fact that it is used handheld.
For marine applications, 10-25 times is optimal. In addition, it should have a good aperture ratio and a large field of view.
What is image stabilization and why is it important?
The binoculars are handheld and even if a person thinks that he is standing or lying motionless, processes occur in his body that create a “shaking” effect - the heart pumps blood, the position of the body changes in the inhale-exhale mode, etc. If you hold the binoculars for a long time on outstretched arms, then the tension in the muscles will also make itself felt and the quality of the “picture” received by the eye will not make you very happy. The fact is that the human brain to some extent compensates for the moving image and when observing through binoculars it seems to us that it is stable in the center of the visible area. But at the edges of the image, the brain seems to lack data for approximation. And the greater the magnification or the smaller the viewing angle, the smaller the visible area. It is for this reason that we do not recommend high magnification binoculars, and for binoculars with a magnification greater than 15x, you must purchase a tripod.
And we are talking about a situation where the person holding the binoculars is on a hard, stable surface. In the conditions of a moving yacht, during observation, binoculars also experience the influence of constant vibration, as well as pitching, because the concept of “complete calm” does not apply to such a sensitive instrument as marine binoculars.
The built-in image stabilizer does not eliminate vibrations at all. But it sharply reduces their amplitude, they become smooth and no longer interfere with observation. The stabilizer is not capable of leveling out one-time sharp jerks, for example, a wheel falling into potholes at speed or a ship “falling from a wave.” But it removes or reduces pendulum-type vibrations: engine vibrations, the influence of sea waves or natural vibrations of the hands.
Binoculars can use several types of stabilization.
Optical stabilization. Uses optical path variation within the binocular to compensate for motion. This type is suitable for all activities where image stability is important, such as when studying birds or when using high magnification binoculars.
Electronic stabilization. Uses electronic sensors to detect movement and mechanisms to compensate for it. It's an ideal choice for outdoor activities such as hunting or sea travel, where hand shake can significantly interfere with viewing the area.
Gyroscopic stabilization. Includes gyroscopes to maintain image stability. Such systems are often found in professional and marine binoculars where the highest image stability is required, even with strong movements.
The choice of stabilization type depends on the specific conditions of use of the binoculars and personal preferences. Optical and electronic stabilization are ideal for high-impact activities where vibration is common, such as on a boat or while driving. Gyroscopic stabilization is most effective in situations where long-term observation with high accuracy is necessary, for example, during sea travel.
The choice between these types of stabilization also affects the price and weight of the binoculars. Models with electronic or gyroscopic stabilization are often more expensive and heavier than binoculars with or without optical stabilization.
It is important to note that image stabilization may not be as critical for some uses, such as theater or urban surveillance, where observer movement is limited and has less impact on image stability. In such cases, it may be preferable to choose binoculars that are lighter and cheaper, even if it means forgoing image stabilization.
Which binoculars to use in low light?
If you are looking for marine binoculars that will provide high-quality visibility in low light, pay attention to characteristics such as aperture and twilight factor.
The aperture of binoculars is a parameter that characterizes its ability to collect light. It is determined by the square of the exit pupil diameter (which in turn is the ratio of the lens diameter to the magnification) and affects the brightness and clarity of the image, especially in low light conditions. The aperture of binoculars is important when making observations at twilight and at night, as well as when studying objects in cloudy weather or in shady places.
The higher the aperture, the better the binoculars cope with tasks in low light conditions, providing a bright and clear image. For example, a 7x50 binocular will have a high aperture ratio thanks to its large 50mm lens, making it an ideal choice for astronomical observations or hunting at dusk.
But at the same time, high-aperture binoculars are usually larger and heavier due to large lenses, which can be inconvenient for long-term observations without a tripod or when transporting over long distances is necessary.
Do not forget also that high magnification can narrow the field of view and sensitivity to pitching, which is important in swimming conditions.
Therefore, when choosing marine binoculars, it is worth considering the conditions in which they will be used and finding a balance between aperture ratio, magnification and ease of use.
Twilight factor is a measure of the performance of binoculars in low light conditions. It is calculated as the square root of the product of the magnification factor and the diameter of the output lens.
A high twilight factor (eg over 20) means the binoculars are well suited for use at dusk or dawn when light levels are low.
