The new PVS-3151C-MOD is the Wide Field-Of-View variation of the renowned dual-tube goggle system PVS-31C-MOD. 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 while retaining all the unique features of the PVS-31C-MOD system.

The GSCI PVS-31C-MOD is the modified and modernized dual-tube night vision binocular system from GSCI.

Since its first introduction back in 2014 PVS-31C until now has been widely regarded as a highly versatile, reliable and easy-to-operate unit. While retaining all features that users valued in the GSCI PVS-31C, the new GSCI PVS-31C-MOD adds in more ergonomic design coupled with improved functionality. It now accommodates more features such as a dedicated Instant-On-IR button: this enables to quickly and momentarily engage IR illuminator without having to operate the switch. The connector located at the front of the unit is used to supply power to the unit from almost any power source: external battery pack, USB power bank, 12V car socket and so on.

These and many other options bring the GSCI PVS-31C-MOD to a new level in performance, functionality and value.

The fact is that a "dual tube" night vision optical system has proven to be more effective and safe for low light conditions compared to a "pseudo binocular" system, commonly known as "PVS-7", which is a "one lens - two eyes" type of NVD.

The crucial issue in modern military is the "survivability" of a soldier.

Depth perception of such "dual tube" device allows using this set for operating various machines, boats etc., in addition to basic ground operations.

PVS-3151C is considered as the most favorable night vision goggles in new procurements regardless the higher cost while comparing with "one-tube-NVD".

PVS-3151C is high performance modular, multi-purpose night vision binoculars. Precisely and ruggedly built housing and optics meet and in some cases exceed military specifications.

PVS-3151C can be used as a handheld device or with head gear, helmet mount assemblies for hands free use. Device has a built-in short range Infrared Illuminator, light overload sensor and Manual Gain Control (optional, with selected IIT).

PVS-3151C works with a single AA battery or with a single CR123 battery.

PVS-3151C is compatible with most IR laser aiming and illuminating devices.

PVS-3151C is fully MIL-STD-810E compliant and ITAR-free, Canadian Made System.

Pros and cons for ECHO when compared to high-end devices (Gen3 FOM 2100+, 4G etc)


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.


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.


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.

Image Intensifier Tube 4G

Photonis 4G NIGHT VISION Standard defines the minimum performance specifications giving end-users the capability to operate MULTI-MISSION NIGHT VISION. 4G NIGHT VISION Standard also implies a modification of the Military Standards of Night Vision testing. From the lowest light levels of desertic areas in Afghanistan (defined at Night Level 6 or less than 100µlx) up to the very demanding aerial applications.
4G NIGHT VISION Standard is not about Technology, it is all about performance and capabilities delivered to end-users. Challenging the Complexity of Light.
1 - An Extended Bandwidth
An Extended Bandwidth of photon collection to deliver a consistently high image quality in all environments (from below 400nm to above 900nm)

2 - High FOM
A FOM (figure of merit being Signal to Noise Ratio times the Resolution : SNR* R) above 1800.

3 - High resolution
A Resolution always superior to 57 lp/mm even in the most polluted light environments such as urban areas or when entering a building where the light is suddenly switched on

4 - Small halo
A Halo size never larger than 0.7mm around the brightest objects seen in the image to provide the highest details around the light sources

Elite : High Figure of Merit (FOM) 2200+ resolution option
ONYX : Black & white vision, white phosphor option
