This is a production item for us, not a unit that somebody doesn't want anymore. I keep getting messages asking for pictures through both tubes. The picture in the listing is indicative of what you can expect. We DO NOT sell units with blemishes in zone 1 nor anything worse than a couple specs in zones 2 and 3. These are the kind that will disappear when you use them in the dark.

These are the minimums & maximums from the contract and reside in the public domain. So What Does This Mean? Let's tackle where the Omni 7 stands compared to other options. The two specifications most often compared are the Figure of Merit (FOM), and the Resolution. FOM was not a requirement in the Omni 7 specs. However, we can calculate it by multiplying the Resolution by the Signal to Noise Ratio. For the Omni 7, this is 64 lp/mm x 28 = 1792. Let's compare with the alternatives out there.

Not that there are not reasons to seriously investigate these other options; just that the Omni 7 should usually be considered a valid competitor. For a detailed account of what these specifications actually measure, look further down this page. What Are The 1431 MK2 Omni7'S System Specifications?

The Argus Company manufactures the BNVD 1431 MK2 binocular night vision housing. They improved the MK1 in many ways. Some of the key features and specifications of the MK2 include. Improved seals to prevent water and dust ingress.

Improved screws that are more durable and less likely to strip. Longer IPD stop screws to provide a wider range of adjustment. Built-in IR illuminator for low-light and no-light conditions.

Redesigned pods that are more ergonomic and durable. Manual gain control that enables the user to adjust the brightness of the unit to their personal preference. A single AA battery powers the Argus BNVD 1431 MK2. Its durability, features, and low price make it a popular choice for many users. Why Do We Base Our Systems Off The OPFOR "Canadian Custom" Housing?

The Canadian Custom 1431 is lighter, tougher, and has better quality control than the standard version. It would take many extra hours to bring a standard BNVD up to the OPFOR standard. By starting with the OPFOR housing, we begin our journey with the best materials and work from there. And Finally, Why Are AI BNVD 1431 Mk2 Units Special? It may seem like there is not much else to do, but details matter. The journey continues with fixing the. 1431's pod switch issue. Next, solder joints are strengthened and key channels are clearanced to avoid wire chafing. The tubes are mechanically centered in the pods to tighten collimation for less eye fatigue from long term use.

The aluminum D-collars are a nice touch as well. Every unit is built in a 100% clean room facility with scrubbed air and assembled in a downdraft cabinet.

Resolution in Ip/mm: This is just another way of saying how fine the picture is. Just like your TV in Megapixels, as the number increases, this is good.

Just think of visual static and you have it. The higher the transference, the more electrons there are to photo-multiply. Another measure of of sensitivity but this time particular to a wavelength of light in the Near IR spectrum.

Phosphor Type: P-43 is modern green phosphor, P-45 is white phosphor, P-22 is green phosphor used in old American systems and some foreign systems (same difference). EBI x10^-11: Equivalent Background Illumination.

Think of this as the glow that your night vision tube just makes on its own. Now think of it as an EVIL glow. First two pictures are stock pics. The second two are from a contract we recently delivered to a law enforcement agency in the midwest. They got five 1431s and two PVS-14s.

This item falls under the ITAR. If you are in a foreign country or a foreign person in the United States, do not order this! Don't have it sent to your forwarding service. Don't have it sent to your family member.
