The ATN PS31-3W is an advanced night vision goggle that has garnered attention from both professionals and enthusiasts alike. As an upgraded version of the PS15, it addresses previous shortcomings and introduces new features that push the boundaries of what’s possible in civilian-accessible night vision technology. Designed for versatility, this goggle caters to a wide range of nocturnal activities, from tactical operations to wildlife observation and night hunting.
Key Specifications
Before diving into the details, let’s outline the core specifications of the ATN PS31-3W:
- Magnification: 1x
- Objective Lens: 22.5 mm
- Field of View: 50°
- Resolution: 64 lp/mm
- Generation: 3
- Minimum Focus Distance: 9 inches
- Battery: CR123
- Weight: 1.27 lb
These specifications hint at the goggle’s capabilities, but the real story unfolds in its performance and features.
Design and Build Quality
The ATN PS31-3W impresses right out of the box with its sleek, articulating design reminiscent of the renowned L3 PVS-31. However, it’s not just a mere clone – ATN has incorporated unique features that set it apart.
- Ultra HD cores bring you cutting edge technology with higher resolution, faster optics, and millions of vivid colors
- Whether you plan to hunt, explore terrain at night, provide security, or are in Law Enforcement – ATN has the right model to fit your needs
- Ease of use in an ergonomic package
The goggle boasts a robust construction with metal monocular pods, instilling confidence in its durability. While this adds slightly to the overall weight compared to polymer alternatives, the trade-off in ruggedness is well worth it for serious users who demand reliability in challenging conditions.
The entire unit is built to withstand temperatures ranging from -59 to 120°F, making it suitable for use in extreme environments. Its IP65 water-resistant rating ensures protection against water and dust, while fog-proof properties prevent internal condensation. The exterior features a matte finish that resists scratches and reduces reflections, crucial for tactical applications.
Advanced Optics and Image Quality
At the heart of the ATN PS31-3W are its third-generation white phosphor image intensifier tubes, sourced from industry leader L3. These top-of-the-line tubes deliver outstanding low-light performance, producing crisp black and white imagery that’s easier on the eyes compared to traditional green phosphor displays.
The 22.5mm objective lenses offer an impressive 50° field of view, significantly wider than the standard 40° found in many competing models. This expanded peripheral vision is a game-changer for users tracking moving targets or maintaining situational awareness in dynamic environments.
With a resolution of 64 lp/mm, the PS31-3W produces crystal-clear images even in extremely low-light conditions. Users report being able to navigate dense woodland and spot wildlife at impressive distances, even on moonless nights. The goggle’s minimum focus distance of 9 inches also allows for close-range use, adding to its versatility.
While there is some slight blurring towards the edges of the field of view, it’s minimal and doesn’t significantly detract from the overall viewing experience.
Innovative Features
The ATN PS31-3W is packed with features that enhance its usability and performance:
Articulating Design: The independently rotating monocular pods allow for single-eye use or the ability to flip one pod up and out of the way as needed. This flexibility is invaluable in situations requiring quick transitions between night vision and normal sight.
Adjustable Diopters: Unlike some competitors, the PS31-3W includes adjustable diopters on each eyepiece. This allows users to fine-tune the focus to their individual eyesight, ensuring the clearest possible image.
Built-in IR Illuminator: An integrated infrared illuminator provides additional illumination when ambient light is extremely low. The auto IR mode is particularly useful, activating only when needed to conserve battery life.
Magnetic Auto-Off: Clever magnetic switches in the pods automatically cut power to the tubes when rotated up. This feature not only preserves battery life but also eliminates the need to fumble with power switches in the dark.
Bright Light Cut-Off: This protective feature safeguards both the user’s eyes and the sensitive image intensifier tubes from sudden bright light exposure.
Automatic Brightness Control: The goggle automatically adjusts brightness based on available ambient light, ensuring optimal image quality without manual intervention.
Performance in the Field
Real-world testing of the ATN PS31-3W has consistently yielded impressive results. Users report exceptional low-light performance, with the ability to clearly observe subjects at distances up to 500 yards under favorable conditions. The wide field of view and high-resolution image make target acquisition and tracking significantly easier compared to narrower alternatives.
The goggle’s hands-free operation, achieved through head-mounting, is a significant advantage for users engaged in activities requiring manual dexterity. Whether you’re navigating rough terrain, handling equipment, or even engaging in close-quarters activities, the PS31-3W remains securely in place without impeding movement.
Battery life is another strong point, with users reporting up to 60 hours of operation from a single CR123 battery. This longevity is further enhanced by the auto-off feature when the pods are rotated up. For extended missions, an optional external battery pack can be added, though most users find the standard battery life more than adequate for typical outings.
The built-in IR illuminator performs well for close-range work, such as map reading or navigating in complete darkness. However, for long-range observation or in extremely dark conditions, pairing the PS31-3W with a more powerful external illuminator can enhance its capabilities even further.
Comparison to Competitors
At a price point of around $7,500, the ATN PS31-3W represents a significant investment. However, when compared to similar setups from other manufacturers, which can easily exceed $10,000, its value proposition becomes clearer.
The closest competitor is likely the BNVD-1531, which offers similar features at a comparable price. However, the PS31-3W edges out with its more durable metal housing and superior auto-off mechanism. When compared to the military-grade L3 PVS-31, the PS31-3W offers approximately 80-90% of the performance at nearly half the price, making it an attractive alternative for civilian users who don’t require the absolute cutting edge of military technology.
