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 it will be necessary 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:

• improved quality of optics;

• significant increase;

• expanded field of view;

• obligatory 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 prismatic systems;

• additions - compass, rangefinder;

• impact resistance;

• powerful photosensitivity;

• confident work even when shaking and rolling;

• buoyancy (the ability to stay on the water).

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.

Then it is already possible to decide how powerful the binoculars are required. Excessive zooming on a yacht or boat is not really necessary. It is quite possible to limit ourselves to the index 7-10.More serious optical instruments are needed mainly by professional seafarers navigating large ships along distant ocean routes. The next important point is the brightness, or rather, the amount of collected light, which depends on the cross section of the lens.

The larger it is, the better you can control the situation in fog, at dusk or even on a moonless night. In addition to the section, the special treatment of lenses, which some manufacturers resort to, also plays a role. The so-called visibility range is also worth evaluating. It shows how wide an area can be viewed at a distance of 1 km.

This, however, does not end the list of criteria. It is imperative to check:

• how well the binoculars hold in your hands;

• whether it is rubberized;

• how much the device costs (this point also cannot be discounted).

It is quite difficult to find 100x binoculars on the mass market. However, the significance of such a characteristic as multiplicity does not diminish from this. And in this regard, a very good solution can be considered KANDAR 10-60x50... 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 200 m;

• the minimum level of magnification is 10 magnifications;

• twilight factor 22.4;

• Porro prisms;

• 5mm exit pupil;

• the ability to adjust the distance between the pupils;

• filling with gas;

• plastic case.

A good alternative might be Nikon Action EX 10x50 CF WP... This is a nitrogen filled night marine model. The optical magnification reaches 10 units, and at a distance of 1 km it will be possible to see an area of ​​114 m. Focusing is in the center. Other features:

• diopter correction is provided;

• the twilight factor level - 22.4;

• 5mm pupil

• exit pupil extension by 1.72 cm;

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

• protection from 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 Farvision BKSH 20x50 version. Some experts believe that this is the best Russian-made binoculars.

The model is also supported by a 20-fold increase. The field of view (visible) reaches 70 degrees. Pehan's 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 distance between the pupils can be adjusted from 5.6 to 7.4 cm.

Important points:

• cases made of durable plastic;

• rubberized performance;

• total tightness;

• rubber eyecups;

• standard temperature range from –40 to +50 degrees;

• mounting on a tripod is done directly, there is no need for an adapter;

• pouch bag and lens caps are included in the package.

Professional binoculars for use at sea are also produced by other companies in Russia. A vivid confirmation of this is the "Zenith BSV 16x40". 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 gyrostabilizer 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.

The optics are based on Roof prisms. The large aperture and multi-layer surface coating guarantee the highest quality images even in light conditions. The binoculars were originally 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 enlightened;

• connection to an external power source is 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.

The description emphasizes the clarity and clarity of the picture, excellent color reproduction. The case is protected from moisture, resistant to rain and moisture. Inertial stabilization eliminates the need for power supply, and focusing is possible from –7 to +7 diopters.

Another German-made binocular is the Bresser Nautic 7x50 WP / CMP. This model guarantees adequate protection at dusk and on rainy days. It will be possible to see small details of ships at a great distance. A multiplicity of 7 with a diameter of 50 allows observation in open water bodies, regardless of the weather. The body is quite robust, rubberized, and the nitrogen filling prevents condensation from forming.

The advantages are:

• internal compass;

• distance measurement;

• calculation of the dimensions of objects;

• backlight mode;

• coverage of the plot is 124 m at a distance of 1 km.
