Choosing marine binoculars

Quite a few people find it important to figure out how to choose the right marine binoculars. To choose correctly, you need to study the multiplicity and other characteristics, the value of each parameter. And also you will need to pay attention to the best powerful models with and without stabilization.


Traditionally, marine binoculars are considered an attribute of a gallant captain. But if we digress from the romance, and look at the practice, then it is obvious that this is just a working tool. It must allow continuous monitoring of everything that happens around the ship. Marine binoculars differ from land models:

  • higher quality optics+

  • significant increase+

  • widened field of view+

  • mandatory all-weather (the sea is not a hike, you cannot set up a camp there, and thereby free yourself from the need to constantly monitor the situation around)+

  • execution on complex prism systems+

  • additions – compass, rangefinder+

  • impact resistance+

  • powerful photosensitivity+

  • confident work even when shaking and rolling+

  • buoyancy (ability to stay on water).

Selection Tips

It is a mistake to think that you can choose the right binoculars for the sea or a vast lake, focusing only on magnification. In fact, the first criterion is tightness.

It must be understood that on boats that are constantly wet, no waterproofing will provide adequate protection. And also it is worth considering that even moisture-resistant models can suffer in the cold. The higher the water resistance index, the more perfect, but also more expensive, the model.

Then you can already decide how powerful the binoculars will be required. Excessively large approaching on the yacht or boat is not really needed. It is quite possible to limit the index 7-10. More serious optical devices are needed mainly by professional sailors leading large courts on far ocean routes. The next important point is brightness, more precisely, the amount of the light-generated light, depending on the cross section of the lens.

What it is more, the better you can control the situation in the fog, at dusk or even in a moonless night. In addition to the section, plays a role and special processing of lenses to which individual manufacturers are resorted. It is worth measuring and the so-called visibility range. It shows how wide the plot will be considered at a distance of 1 km.

On this, however, the list of criteria does not end. Be sure to check:

  • how well binoculars keeps in his hands+

  • He rubs up+

  • How much does the device cost (this moment cannot be discounted too).

It is quite difficult to meet 100x binoculars in mass sales. However, the significance of such a characteristic as multiplicity does not decrease from this. And in this regard, a very good solution can be considered KANDAR 10-60×50. With an image magnification of 60x, these binoculars have a 50mm lens. Other important features:

  • the viewing radius at a distance of 1000 m is equal to 200 m+

  • minimum magnification level – 10 magnifications+

  • twilight factor 22.4+

  • Porro prisms+

  • 5mm exit pupil+

  • the ability to adjust the distance between the pupils+

  • gas filling+

  • plastic case.

A good alternative might be Nikon Action EX 10×50 CF WP. This is a nitrogen filled overnight marine model. The optical magnification reaches 10 units, and at a distance of 1 km it will be possible to consider an area of ​​114 m. Focus is centered. Other features:

  • diopter correction is provided+

  • twilight factor level – 22.4+

  • 5mm pupil+

  • extension of the exit pupil by 1.72 cm+

  • change in the distance between the pupils from 5.6 to 7.2 cm+

  • protection against dust and moisture+

  • tripod adapter+

  • weight 1.02 kg.

According to a number of experts, only binoculars with stabilization can be among the best. An excellent option in this sense is the version “Farvision BKSH 20×50”. Some experts believe that this is the best Russian-made binoculars.

It is characterized by an enlarged visual field. The design is optimized for observation in difficult situations, including when the support is unstable and under vibration influences.

The model is also supported by a 20-fold increase. Field of view (visible) reaches 70 degrees. Pehan prisms are installed inside the binoculars. An important advantage is inertial magneto-dynamic stabilization with vibration correction up to 6 degrees. Isolated focusing is ensured and the pupil distance can be adjusted from 5.6 to 7.4 cm.

Important points:

  • cases made of durable plastic+

  • rubberized version+

  • total tightness+

  • rubber eyecups+

  • standard temperature range from -40 to +50 degrees+

  • direct mounting on a tripod, no adapter required+

  • pouch bag and lens caps included.

Professional binoculars for use at sea are also produced by other companies in Russia. A vivid confirmation of this is the “Zenith BSV 16×40”. An important feature is the housing protected from moisture. The system is thought out in such a way as to guarantee a static image even when observing from a moving vehicle. A gyro stabilizer is provided that dampens angular movements of the body up to 6 degrees in any direction and keeps the sighting axis in a constant position.

Optics based on Roof prisms. Large aperture and multi-layer surface coating guarantee the highest quality images even in light conditions. The binoculars were initially thought out so that they would be convenient to use at dusk or under continuous low clouds. Other important features:

  • binoculars can be placed on a tripod+

  • all surfaces are coated+

  • connection to an external power supply possible+

  • confident work at a temperature of -25 degrees and in heat up to +45 degrees+

  • the ability to work without external power supply – in the mode of a simple optical device+

  • gas filling is not provided.

You should also pay attention to good German binoculars with stabilizer for sea travel. For example, on Zeiss 20×60 T * S Image Stabilization. Designed for image stabilization, this model features superior magnification and aperture.

The description emphasizes the clarity and clarity of the picture, excellent color reproduction. The body is protected from moisture, resistantly opposes rain and moisture. Inertial stabilization allows you to do without power supply, and focusing is possible from -7 to +7 diopters.

Other German Binoculars – Bresser Nautic 7×50 WP / CMP. Such a model guarantees proper protection at dusk and rainy days. You can see small details of the courts at a large distance. Multiplicity 7 with diameter 50 allows you to perform observations on open reservoirs, regardless of weather. The housing is quite strong, rubbing, and filling with nitrogen prevents condensate.

The advantages are:

  • Internal compass+

  • Distance measurement+

  • calculation of dimensions of objects+

  • Backlight mode+

  • Plot coverage 124 m at a distance of 1 km.
