Key Differences Between the PVS-31 and PVS-14

The PVS-31 and the PVS-14 differ across several critical aspects, including ergonomics, durability, and battery life, making them tailored to different user preferences and operational requirements.

Ergonomics

When it comes to size and weight, the PVS-14 is more compact and lightweight, measuring 3.5 x 2.8 x 2.4 inches and weighing just 0.71 lbs with a battery. On the other hand, the PVS-31 is slightly bulkier at 4.2 x 4.2 x 3.4 inches and weighs 0.99 lbs with a battery. This makes the PVS-14 a more portable option for users prioritizing lightweight gear, while the PVS-31’s ergonomic design focuses on reducing head-borne weight and improving overall balance during extended use.

Durability

The PVS-31 stands out in terms of durability, being waterproof up to 66 feet for two hours, compared to the PVS-14, which is waterproof up to 33 feet for the same duration. This makes the PVS-31 a better choice for operations in harsher or wetter environments.

Battery Life

Battery life is another critical factor where the two models differ. The PVS-31 offers 15 hours of usage on a single AA battery, extending up to 50 hours with four batteries. The PVS-14, however, provides superior battery longevity with 30 hours on a single AA battery and 60 hours with four batteries. This makes the PVS-14 ideal for extended operations where battery life is a priority.

Applications and Use Cases

Overall, the PVS-31 is better suited for users prioritizing advanced features, enhanced durability, and superior situational awareness in challenging conditions. Meanwhile, the PVS-14 is an excellent choice for those who prefer a more compact, lightweight design with extended battery life. By carefully assessing these key differences, users can make an informed decision that best matches their operational needs and budget.

Differences Between L3Harris AN/PVS-31A, L3Harris AN/PVS-31C, L3Harris PVS-31K, and Elbit White Phosphor F5032 (PVS-31D)

When comparing the L3Harris AN/PVS-31a, AN/PVS-31C, PVS-31K, and the Elbit White Phosphor F5032 (PVS-31D), several differences stand out in terms of design, performance, and intended operational use.

L3Harris AN/PVS-31A

The AN/PVS-31a is a standard issue dual-tube goggle widely used by military operators for its exceptional clarity and build quality. It features unfilmed white phosphor tubes that provide better brightness and clarity compared to older systems with green phosphor tubes. While lightweight and ergonomic, this unit does not feature articulating optical pods, which means the entire goggle must be flipped up for stowing. The AN/PVS-31a is more geared toward users prioritizing mil-spec reliability and proven performance within an established framework.

L3Harris AN/PVS-31C

The AN/PVS-31C shares many similarities with the AN/PVS-31a, including unfilmed white phosphor tubes and a dual-tube, non-articulating design. However, the AN/PVS-31C is often noted for having updated internal components that improve image resolution and durability. Additionally, the build emphasizes compatibility with existing helmet-mounted systems while offering slight performance enhancements over the AN/PVS-31a. This model is often viewed as an incremental upgrade over its predecessor, targeting a similar operator base.

L3Harris PVS-31K

The PVS-31K represents a modern, lightweight evolution of the previous 31-series models. One of its standout features is the inclusion of articulating optical pods, allowing users to flip each monocular independently. This not only reduces potential damage but also increases operational flexibility when transitioning between dual and single-eye use. The PVS-31K continues to utilize cutting-edge unfilmed white phosphor technology, offering high image clarity and enhanced low-light performance, but it also introduces efficiency in stowing and deploying the goggle in confined or variable environments. Its lightweight construction makes it suitable for long missions with reduced neck strain.

Elbit White Phosphor F5032 (PVS-31D)

The Elbit F5032 (PVS-31D) differentiates itself with its articulating housings and exceptional thin-filmed white phosphor tubes. While other models in the L3Harris series utilize unfilmed tubes, the Elbit F5032 leverages thin-filmed technology, offering robust durability with slightly reduced performance in extreme low-light settings compared to unfilmed counterparts. The F5032 stands out because of its on-board AA battery power (with optional battery pack), lightweight design, and manual gain adjustments. These features make it operator-friendly, particularly for users who require independent pod control for enhanced versatility during activities such as reading light conditions or integrating with thermal devices. Additionally, its stowage capability without flipping the goggles onto the helmet mount reduces snag hazards and improves practicality in tight spaces.

Summary of Key Differences

Each model offers specialized advantages depending on the operational environment, with the L3Harris models prioritizing unfilmed technology and lightweight reliability, and the Elbit F5032 excelling in flexibility and user-adjustability. Users should select the model that best suits their mission requirements, ergonomic preferences, and operational constraints.
