How to choose a binocular night vision goggles that suits you?

1. Clarify the purpose of use

Outdoor adventure and observation: If it is mainly used for outdoor adventure, such as observing wild animals, night hiking, etc., you need to choose a binocular night vision goggles with a wide field of view, good low-light observation ability and strong portability, so as to quickly find the target and observe its dynamics in the natural environment. Like the PVS-31 head-mounted binocular low-light night vision goggles, it has a third-generation image intensifier, clear and layered imaging, 50-72mm adjustable interocular distance, suitable for people with different face shapes, and also has the characteristics of a minimum focusing distance of 0.25 meters in a completely dark environment. Maps can be viewed in a completely dark environment, which is very practical and very suitable for outdoor adventures.

Police law enforcement and security: Police law enforcement requires night vision devices to be able to clearly identify targets at long distances, have high resolution and image enhancement capabilities, and preferably have video and photo functions for evidence collection. In addition, concealment and reliability are also important considerations. For example, portable binocular night vision devices have a large high-definition color screen with a resolution of 1920*1080, clear and delicate picture effects, and have multiple working modes such as infrared, low light, black and white fusion, and color fusion. They can record and take pictures, and also have fog penetration and anti-shake functions. They can provide strong support for law enforcement personnel in a variety of complex environments and effectively solve the problem of low visibility of front-line law enforcement personnel at night.

2. Pay attention to performance parameters

Magnification: Generally speaking, the higher the magnification, the clearer the details that can be observed, but the field of view will be narrower accordingly. If you need to observe distant targets, such as observing distant animals in the wild or observing ships at sea, you can choose night vision devices with higher magnification, which can meet the needs of long-distance observation.

Field of view: The larger the field of view, the wider the range that can be observed at the same time, which is conducive to quickly scanning the surrounding environment and discovering potential targets. For scenes that require a wide field of view, such as outdoor adventures and police law enforcement, night vision goggles with a larger field of view are more suitable, which can provide a wider field of view and enhance situational awareness.

Resolution: Resolution determines the clarity of the image. Night vision goggles with high resolution can present richer details and help accurately identify targets. When choosing, you should try to choose products with higher resolution, which can provide clearer image effects.

Detection distance: Different binocular night vision goggles have different detection distances in total darkness and low light environments. If you often need to use it in a total darkness environment, such as night military operations or security monitoring, you should choose a product with a longer detection distance in total darkness; for scenes with a certain amount of ambient light, the low light visible distance is more important. We can choose according to the actual use environment.

3. Consider the use environment

Ambient light conditions: If there is a certain amount of low light in the use environment, such as city night scenes, moonlight, etc., then you can choose a night vision device with good low-light observation capabilities; but if it is often used in a completely dark environment, such as underground caves, unlit fields, etc., you need to choose a product with excellent all-black performance. Usually, such products will be equipped with a strong infrared auxiliary light source or use more advanced image enhancement technology.

Weather conditions: In severe weather conditions, such as foggy days and rainy days, the performance of night vision devices may be affected. Some high-end binocular night vision devices have a fog-penetrating function, which can penetrate fog to a certain extent and improve the observation effect. For example, portable binocular night vision devices have fog-penetrating and anti-shake functions, and can be used normally under a variety of complex weather conditions.

Temperature and humidity: If you need to use night vision devices in cold, hot, or humid environments, then the operating temperature range and waterproof and moisture-proof performance of the product need to be considered. For example, the PVS-31 binocular night vision device has an operating temperature range of -40℃ to +55℃, a relative humidity of 98%, and a dust and water resistance rating of IP67, which can adapt to relatively harsh environmental conditions.

4. Weighing portability and comfort

Weight and volume: For users who need to carry for a long time or move frequently, such as outdoor explorers and military and police personnel, lighter weight and smaller volume can reduce the burden and improve the convenience of use. Like the PVS-31 head-mounted binocular low-light night vision device, it is small in size, light in weight, compact and sturdy in structure, comfortable to wear, and will not bring too much burden to the user.

Wearing method: The main wearing methods of binocular night vision devices are handheld and head-mounted. Handheld is suitable for short-term observation or scenes that require flexible operation; head-mounted can free your hands and is convenient for use in action, such as night patrols, military operations, etc. PVS-31 has both handheld and head-mounted usage methods, which can be flexibly selected according to actual needs.

Eyepiece spacing adjustment: Different people have different eye spacing. Binocular night vision devices with adjustable eyepiece spacing can better meet the needs of different users and provide a more comfortable observation experience. Products such as PVS-31 and PVS-7 head-mounted binocular monocular low-light night vision devices have the function of adjustable eyepiece spacing.

5. Consider the budget

Generally speaking, the price of entry-level binocular night vision devices is below US$5,000. Such products can meet basic night observation needs, but may be relatively limited in performance and functions, suitable for ordinary outdoor enthusiasts and users with limited budgets.

The price of mid-to-high-end products ranges from US$5,000 to US$20,000. They usually have better imaging quality, longer detection distance, more functions and more reliable performance. They are suitable for professional users who have high requirements for night vision device performance, such as military police, scientific researchers, etc.

High-end or professional-grade binocular night vision goggles cost more than US$20,000 or even higher. These products often use the most advanced technology and materials and have excellent performance and functions, but they are also relatively expensive and are generally used in special high-end fields such as military and scientific research.
