I don't understand why there is @ $1,400 swing on these two units. I can not find a solid handle on the differences between these two. Can someone with knowledge of the systems explain this?

Does a BNS have a submerged rating? How long?

Is there a difference in the accuracy window between the units?

FOV - seems to be the same - is it?

Gain and focus capacity the same?

Looks like it is possible to get the same quality tube - correct?


TIA
 
Re: What are the real differences? BNS v PVS 22?

The BNS is made by OSTI for Night Vision Depot right along side the PVS-22. The BNS has the same ratings as the PVS 22 for everything but the tube. The BNS has an ITT, Hand Selected 9815 SLG tube with a Data Sheet. You see Night Vision Depot picks out the best of their Pinnacle tubes and sends them to OSTI for installation in the PVS-22/BNS Housing. In addition OSTIs shock mitigation system for recoil management is present in both units, as such, I would not worry about using a Pinnacle tube on a higher recoiling weapon. Mine has only seen .308 and no problems there.

The PVS 22 comes with a Mil Spec tube and as far as I know, no data sheet. The price difference in the end units is way more than the price difference between the two tubes making the BNS a great value in a clip on.

So Same, Same, except for the tube.

Ohh and the published submersion rating is 66 feet for the PVS-22 I will check and ensure that the BNS is as well but I am tending to bet that it is.

The BNS does have the same submersion level as the UNS. Also shock mitigation of both units is well above .308's. We've shot our share of .338's and 50bmg's along with many Mil folks we work with within our training sessions.

On last question and I am sure the answer is 'no problem' but - it is Oregon - I *assume* there is no problem with sitting for several hours exposed in a rain storm with a BNS - correct?

With a submergence ratting to 66 feet below sea level you should be just fine. What scope are you planning to use this in front of?

I dont think you will be leaving anything on the table with a NVD P+ BNS unit over a PVS22.. </div></div>

Unfortunately 6+ weeks now due to the current contract requirements of all PVS-22 body housings that have dramatically increased over the last 6 months. Per month deliveries to the Mil are pretty big nowadays with FLIR (formally OSTI).

This was a big reason the PVS-27 units were restricted to LE/Mil due to supply and demand for such a long time. Funny thing with these nowadays, we can keep these on the shelves as we're only looking at a 1 week lead time for these units if we run out of stock.
 
Re: What are the real differences? BNS v PVS 22?

The difference is in the "pedigree" of the intensifier tube. The BNS has a "commercial" tube, while the PVS-22 has a "milspec" one. Otherwise, the optics and optical systems are identical.

On "commercial" versus "milspec" certified Pinnacle tubes: compare a "commercial" NEPVS-14 with a "milspec" PVS-14, on a side by side "use test," and with your eyes you'll struggle to find the performance difference (besides the minor artifacts unique to each, individual microchannel plate).

Note that there are three different performance "classifications" (with graduated pricing) on the BNS, that differ by such attributes as signal-to-noise ratio: -P, P, and +P. For those, you do get what you pay for.

I stand corrected by the Vic! :)

Re: What are the real differences? BNS v PVS 22?

You got it, Bro! :) Here are my latest observations:

With spring arriving, the raptors are all gone away and the deer have moved out of the open areas into the deeper woods. However, the rabbits are out in force.

I'm quite convinced that rabbits can see 810 nm wavelengths. When rabbits perceive a threat, they become very still. If they think the threat is on top of them they will bolt into deep cover.

When I sweep an area where rabbits are foraging with the 810 nm laser, they go from grazing to sitting still and upright with their ears straight up in the air. Clearly, they are alerted to the beam.

When I dance the 810 nm beam against nearby foliage, which sends reflections everywhere, the rabbits clear out. This signals to me that they clearly see the anomalous movement, flashes, and reflections and perceive them to be possible, predatory threats.

However, when I run the 1000 mw, 860 nm "super-highway" over their heads or explode the beam by blasting it into tree foliage, the rabbits are oblivious. They continue to peacefully graze on grass while the 860 nm "fireworks" explode everywhere.

One night, a domestic house-cat was out stalking the rabbits. I was curious to test its response to the 810 and 860 nm lasers sweeping nearby. It seemed oblivious to both. Interestingly, it got into a tangle with one of the rabbits, and despite the squeals of terror from the rabbit, the rabbit held its ground, appeared to be getting the better of the cat, and quite frankly "powned" it. The cat then tried to escape out of there by running off into a darker area. I then put the 810 nm laser on 10-degree flood and put the "spotlight" on the cat. The rabbit charged full bore at the cat. The cat bolted into the darkness under a canopy of mature evergreens. I put the 810 nm illumination spotlight back on the cat, and the rabbit charged at it again. This time, the cat kept running and running until it was out of sight! It seemed clear to me that the rabbit could see the 810 nm spotlight, but the cat couldn't.

We still need to talk a bit more about your IR lighting testing with critters! :) </div></div>
 
Re: What are the real differences? BNS v PVS 22?

Must get a white paper going with your findings and get some biologist to take some HARD looks into all this. I mean this is not rocket science and something seems to be amiss.

Sorry to go of topic, but maybe another thread in the near future with a published white paper on this could be substantial. Something is definitely going on but all (well most) of the scientist are nay-sayers to what you are experiencing based on their studies of these critters eye makeups.
