The new PVS-1451 is the Wide Field-Of-View variation of the renowned
tactical monocular PVS-14. Its 51-degree field of view provides +71%
area coverage comparing to standard 40-degree FOV units and delivers to
an operator exceptional situational awareness.
There is a vast variety of Night Vision Monoculars available in the World Marketplace. The most popular are PVS-14, MUM-14
as well as a couple of other leading models. While having had 20+ years
"first hand" experience working with a large number of models and
building our own system, GSCI has developed and is glad to present the
very best night vision multi purpose monocular PVS-14C.
This system gathers the latest technology advancements currently
developed. Whatever is missing in other systems/models, you can find in
our PVS-14C...and some more.
BEST USE - The ITAR-free PVS-14C is a natural choice
for off-shore, export users that require a high performance Gen3 Night Vision
Scope for critical surveillance and reconnaissance applications
PVS-14C is built in accodance to GSCI proprietary LDH Concept (Light Durable Housing), has strong, durable, light weight body and the smallest physical dimensions in the industry.
The legendary PVS-14C is a great
choice for conducting combat operations, including dismounted terrain
navigation in extremely low light conditions. The versatile PVS-14C
system can be used in many configurations: hand-held, hands-free,
standalone weapon-mounted, clip-on, and others.
Compared to the PBS14, the PVS-14C has visually different
design of the housing, MIL-SPEC pull-action switch (OFF/ON/IR), manual gain
control knob
(if the selected tube has this feature), has stow safety feature standard, IP67
rating standard, nitrogen purged, comes with the demist shield and the
sacrificial window
Custom order monoculars can be supplied with 4X, 7X, and 10X magnification lenses.
* Also available with Autogated feature on Gen 3 IIT FOM 1600 and 1800 [ Please contact for more details]
* Also available with White Phosphore Tube (IIT Black and White photocathode feature) [ Please contact for more details]

Pros and cons for ECHO when compared to high-end devices (Gen3 FOM 2100+, 4G etc)
Cons
ECHO is commercial grade, when 4G & higher FOM devices are considered to be mil-grade. What does that mean? Mil-grade requirements does not allow black-spots to be in the first nor second sector. Therefore, all tubes that have black-spots in those sectors, are pushed to commercial grade. As a result, rarely you can find an ECHO without blackspots, because otherwise that tube would classified as mil-grade tube.
How much does it affect you? The less light there is, the less visible black spots are. You will be able to see those tiny dots, but when game is on, those spots have never borthered me.
Pros
Similar performance - The Gen3 we had in comparison costs about 60% more, but delivers only slightly better performance than ECHO.
Faster auto-gated - as you can see from video, the halo-size (size of bright light) is smaller with Photonis tube. Thats due to much more efficient autogating. So, in high light conditions ECHO/4G tube will outperform Gen3 tubes.
Conclusion
One might say that ECHO was filmed from closer range (guys moved around when I changed devices). Still, we can say that both devices have pretty similar performance – both devices had noise due to low-light, but the noise on ECHO wasn’t worse compared to high-end / mil-grade Gen3.
When buying commercial grade night-vision like ECHO, you shouldn’t expect clean tubes. There will be black-spots. Otherwise, it would not be so cheap compared to mil-grade tubes.
If your life does not literally depend on it, buying ECHO will definitely save you some money while giving similar level of performance.
Image Intensifier Tubes of Generation III = ECHO, SuperGen®, XD-4™, XR5™
Gen. III tubes differ from the Gen. II+ tubes by their construction of the cathode. Gen. III tubes have a Gallium-Arsenide cathode (GaAs) with more sensitivity for IR-light. The light amplification is around app. 30000 up to 55000 times, the photosensitivity of the cathode is around 900 – 1600 µA/Lm at 2850K and the resolution of the line pairs is 32 – 64 lp/mm (omnibus 1 and omnibus 2 where developed end of the 70s, omnibus 3 and omnibus 4 is a further development of the late 80s. Omnibus 7 is currently* the most powerful Gen. III tube with a FOM value of app. 2300). The performance of Gen. III tubes may vary, depending on type and specifications (omnibus 1 up to currently* 7 Pinnacle), by circa 300%. The life expectancy is around 10000 up to 15000 hours, which is 3 – 4 times longer than the Gen. II tubes. Devices with Gen. III tubes are operating excellent in extremely low ambient light (residual light). The observation image is saturated, sharp, with excellent contrast and recognition of also smallest details. ECHO, XD-4™ and XR5™ tubes with an AUTO-GATING function are excellent suitable for operations in urban area.
