However, the PVS-31’s dual tube configuration gives it a slight advantage in depth perception, particularly in complex environments. 2. Field of View Experience the latest evolution of Image Intensified Night Vision devices from L3Harris, being used in the toughest conditions for the most critical missions by U.S. DoD and Tier 1 Special Operations worldwide.

In conclusion, both the AN/PVS-31A BNVD and the SI/PVS-14 Photonis Echo White Phosphor are excellent night vision goggles that offer a variety of features and specifications. Each model has its own advantages and disadvantages, so it’s important to look at the specs and features before deciding which one is best for your application. This model body similar like PVS 31, its FOV 50° better than PVS 31 original night vision goggles model. It utilize two high performance image intensifier tubes to provide extremely clear and crisp images under the darkest conditions. Below video show the night effect with gen 2+ image tube. It use the same size image intensifer tubes as our Ground Panoramic Night Vision Goggles.One feature that the 1431 shares with the DTNVG is the auto off/on when the unit is stored vertically on a helmet. However, just like the PVS-31, the 1431 can be programmed. The DTNVG can supposedly be programmed as well but it is not something the user can perform. On the 1431 you press the power button 4 times and a red indicator light will blink inside the left eyepiece. You are now in auto off mode. If you press the power button 4 times again then the unit will no longer shut off when stored vertically. You must do this when the 1431 is turned on.

The BNVD’s twin-tube design offers greater reliability in the field against failure or damage versus a single-tube night vision devices. Manual system gain adjustment allows operator to control image brightness to match the environment. The BNVD also can be used as a monocular by rotating either left or right channel, up and out of the way. In The Box Determining which night vision goggles are the most suitable for individual needs can be a difficult decision depending upon ergonomics, durability, and battery life. The AN/PVS-31A BNVD and the SI/PVS-14 Photonis Echo White Phosphor are two of the most popular night vision goggles on the market. Both offer superior situational awareness and several options for customization, as well as a variety of features to consider when assessing their ergonomics, durability, and battery life.

So, there are chances that it might face the same problem. PVS 31 on the other hand, requires 4 1.5 volts AA batteries. One of the most sought after and frequently requested night vision products now on the commercial market—the L3Harris Binocular Night Vision Device (BNVD)!Overall, it’s clear that the PVS-31 and PVS-15 are two of the best night vision systems available on the market today. With their advanced features, rugged construction, and reliable performance, they are the perfect choice for anyone who requires the very best in nighttime vision technology. The DTNVG (Dual Tube Night Vision Goggle) combines the benefits of both RNVG and PVS-31. A design similar to the PVS-31 provides the advantage of dual tube technology, offering excellent depth perception. Night Vision PVS 31 beats Night Vision PVS 15 in terms of resolution. PVS 15 has a resolution of 64 Ip/mm whereas PVS 31 has a resolution of 72 Ip/mm. This means you’ll get a more clear image of your target through PVS 31. The AN/PVS-31A BNVD is a Gen III dual tube goggle designed to improve system resolution and reduce head-borne weight, with a low-profile ergonomic design and improved white phosphor tube technology. It is waterproof to 66 feet for two hours and offers a single AA battery that can last up to 15 hours, or four AA batteries for a battery life of up to 50 hours.
