Looking for the next great deal?!

The NGI/PVS-14 is a Photonis 4G ECHO Hybrid Photocathode (Gen 2+) night vision monocular based on the standard issue AN/PVS-14.  Our professionally-trained and experienced technicians assemble the NGI/PVS-14 according to U.S. Military guide lines, using factory-new parts and Photonis 4G ECHO factory image intensifier tubes.






The Photonis 4G Hybrid Photocathode uses the same technological infrastructure as Generation 2 image intensifier tubes making them a Gen 2+ tube, however, Photonis has pushed the boundaries of the Gen 2 architecture to produce some of the very best tubes on the market for the hunter, sportsman, and enthusiast at a significantly lower cost than Gen 3 image intensifiers. The 4G ECHO tubes used in the NGI/PVS-14 are commercial production units based on the 4G INTENS image intensifier used by many foreign allied military and law enforcement organizations due to export restrictions on Gen 3 image intensifiers*.




The Photonis 4G ECHO is available in both P43 (Green) and P45 (White) Phosphor, and provides excellent performance in high (50%+ illum) and mixed light conditions, however will need more supplemental IR illumination than Gen 3 tubes in extremely dark conditions, and will begin to lose resolution in low light often needed to positively individuals, weapons, and other objects more quickly than Gen 3 tubes. This makes them less suited to law enforcement and military applications where fine detail resolution and PID is mission critical compared to Gen 3 units. However, for hunters, sportsmen, and enthusiasts who need to be able to see in the dark for navigation, movement, general identification, visual augmentation, and range work, they are an excellent and cost-effective option. Now with a 10 year warranty!

NGI/PVS-14 Photonis 4G ECHO Hybrid Photocathode (Gen 2+) P43 Green Phosphor $2514.00/ P45 White Phosphor $2540.00!

Some have PM'd already asking us about specs "since your pricing is so low "are these commercial spec echo's?".  Nope no such thing as a "Commercial Spec Echo Tubes" that were advertised awhile back, this verified from Photonis. Here is a small sampling of the latest Echo tube specs NGI has built up. Yes they have them in green and white flavors.

68lp, SN of 30.8

68lp, SN of 30.5

67lp, SN of 30.3

69lp, SN of 29.8

65lp, SN of 30.2

70lp, SN of 30.8

65lp, SN of 30.1

NO ZONE 1 blems in any of the tubes.

Hey Vic is this an apples to apples comparison? I have one of your L3 filmless WP tubes.  Might considering picking up one of these Gen 2+ for my brother.  Can I take the FOM calcs from the specs above and compare them to the FOM of my tube? Does it work thataway? Thanks.

The L3 filmless will always be a bit brighter and always perform better in low light with much less scintillation even when FOM's may be somewhat closer. It's a strange phenomenon, but the filmless always look better even though specs may be close. Not saying this to pimp L3 filmless like that, it's just how good the filmless tubes from L3 are.

This also goes for Harris and L3 thin filmed. IMHO they still look sharper over the Echo's, but MUCH closer vs. that of the L3 filmless.

Always appreciate your candor. Thanks.

Glad to assist.

Oh, btw NGI is also building these in house and not relying on a 3rd party to build their gear. They also have a 14 day no questions asked warranty return and they will beat any advertised price!

Thank you for the orders!  

Yes no Zone 1 blems and yes these are full kits that include PVS-14 Adapter (J-Arm), Rubber Eye Cup, Daylight Filter, Sacrificial Window, Demist Shield, Soft Carry Case, Lens Cleaning Tissue, Military Maintenance Standards, Warranty Registration Card, Data Sheet all with a 10 year bumper to bumper warranty!

Our pricing is the best out there for the Photonis Echo tubes and we will beat any advertised price but our green $2514 and white $2575 are the lowest pricing we've seen, in stock and shipping daily.

Will these be offered in a dual tube setup?

You bet, no ETA just yet.

quick question:

How does the MTBF lifecycle/longevity on the Photonis 4G compare to traditional Gen2, Gen2+, Gen3 and Gen 3 filmless tubes? I remember reading that tube degradation between true gen 2, gen 3 and filmless was all a little different not only in ultimate longevity but also how quickly they degraded and then held a generally stable performance level until they reached end of life. Do these Photonis 4G tubes offer any significant differences?

What about recoil sensitivity/rating as compared to those traditional NV generations for direct weapon mounting?

Photonis still states 10K hours on their tubes and gradually get darker. We're talking a lot of hours here before you would ever see any mitigation.

As for recoil, PVS-14's are never recommended to be placed on high recoil guns. No need to as they only have a 1.1x native magnification capability.  Best way is to head mount and place an IR laser on  your rifle.  Thank you.

It says "*4G ECHO tubes will not have the same performance as 4G INTENS units or Gen 3 image intensifiers intended for military and LE applications, and while the 4G ECHO does display some Out Off Band (OOB) sensitivity to high powered systems, they do not have sufficient sensitivity for operational use with lower powered OOB devices such as individual weapon aiming lasers and marking lights..."

So no IR lasers for this one?

That’s my question too can you not use IR lasers with it

Would love to know if you can use an IR laser as well?

Yes and No. Some IR lasers work while others will not. Some tubes will see IR lasers while others will not. If you must have the ability to run an IR laser, purchase a Gen 3 tube from our sister company, TNVC!
