The RovyVon GL4 Pro is a compact and budget-friendly IR Laser and Illuminator. Compared to similar offerings in the market, the GL4 boasts a significantly lower price tag, which makes it an attractive option for cost-conscious users.
The RovyVon GL4 Pro has selection levers for controlling the laser modes. Users can choose between a visible laser, an infrared (IR) laser, a combination of both, or simply turn the laser off entirely. Fine-tuning accuracy is achieved via windage and elevation turrets, allowing for precise adjustments to align the laser with the weapon’s sights. A unique feature is the front-mounted battery compartment. This design choice offers a distinct advantage – battery changes can be performed without detaching the sight from the firearm, saving time and effort during operation.
Considering its cost, the RovyVon GL4 Pro’s laser functionality is in a class by itself. A key test involves measuring the alignment between the visible and IR lasers. Our testing reveals a slight one MOA offset, which translates to a minor deviation in point of aim between the two lasers. This deviation is due to the .3-inch vertical separation between the two lasers. While this might seem concerning at first glance, such a minor offset is acceptable for practical use, particularly given the budget-friendly nature of the sight.
Next, we analyzed the power of the GL4 Pro laser. The IR laser clocks in at a measured ~.7 mW, which is considered an ideal balance for use with night vision equipment. Night vision devices typically require a specific range of IR laser output for optimal performance, and the RovyVon GL4 Pro falls squarely within that sweet spot. Additionally, the visible green laser boasts a measured output of 4.68 mW. This measurement translates to excellent daytime visibility, making the sight a versatile tool for both day and night environments.
Understanding how these laser outputs translate into real-world scenarios is vital. The GL4 Pro Laser strikes an epic balance between features and practical applications. For example, the visible laser’s strong output makes it suitable for rapid target acquisition in low-light situations where night vision isn’t necessary. The IR laser, on the other hand, allows for aiming under complete darkness when paired with compatible night vision goggles. This combination provides a significant tactical advantage in nighttime operations.
The RovyVon GL4 Pro boasts a cool white and an IR illuminator, a critical component for effective night vision use. The illuminator’s performance throughout a series of tests sheds light on its strengths and some potential limitations.
The IR illuminator’s beam pattern exhibits a dual personality. On the one hand, the beam pattern features a central hotspot that concentrates light for illuminating targets at a distance. This feature is ideal for situations where you need to identify objects far away in low-light conditions. On the other hand, the beam pattern also offers a significant amount of flood, which fills the periphery with light. This flood helps illuminate targets closer to the user, providing a more versatile illumination profile. Imagine the hotspot being like a spotlight and the flood filling the surrounding area with ambient light – the RovyVon GL4 Pro tries to offer both in a single-beam pattern.
This dual personality, while quite valuable, does carry a potential caveat. Testing reveals the center of the illuminator’s output to be over 3 Watts. While this high output translates well for illuminating distant targets, the brightness might be excessive for close-quarter situations. A very bright illuminator at close range could potentially obscure the target, making aiming under those conditions more difficult. Finding the right balance between distance and close-up usability might involve adjusting your shooting position or momentarily turning off the illuminator for close-range engagements.
The cool white illuminator at ~400 lumens compares favorably to some SureFire weapon lights like the X300/Ultra. Flashlight reviews often overstate lumen output when describing light output. In practical use cases, the ability of the light to punch through fog or windows is the most important tactical consideration. The RovyVon GL4 Pro performs admirably in this regard, especially considering its size, price, and build quality.
The precision and reliability of any sight’s windage and elevation turrets are important factors to consider. These turrets are crucial for zeroing the sight, a process that involves aligning the laser dot with the point of aim of your weapon’s iron sights or telescopic scope. Precise and repeatable adjustments are essential for ensuring accuracy. The RovyVon GL4 Pro adjustments are crisp and offer satisfying tactile feedback, indicating a well-built mechanism. This mechanism effectively held zero of the sight after multiple adjustments during our testing.
While the ease of point-of-aim adjustment is an important feature of the RovyVon GL4 Pro, the zero-hold capabilities are more important. Zero hold refers to the sight’s ability to maintain its zero (alignment) after experiencing recoil or even being detached and reattached to the weapon. After 300 rounds of 9mm and .357 sig, the RovyVon GL4 Pro held its zero with almost no detectable shift in point of aim. This testing demonstrates the build quality and reliability of the sight.
In conclusion, due to its high estimated output, the RovyVon GL4 Pro’s illuminator offers a versatile beam pattern with a potential trade-off for close-quarter use. However, the well-built turrets with precise adjustments and the impressive zero-hold capabilities solidify the sight’s functionality and reliability.
Evaluating night performance is paramount for a night vision laser sight. Our review conducted various tests in different lighting conditions to assess the RovyVon GL4 Pro’s capabilities. The two most important tests were conducted in total darkness and under strong ambient light (near a streetlight)
With the lights completely off, the IR illuminator demonstrates its effectiveness. Testing shows that the illuminator can successfully illuminate targets at distances between 80 and 100 yards. This range provides ample visibility for engaging targets in typical nighttime environments.
The RovyVon GL4 Pro holds its own even under more challenging lighting conditions. In a scenario with bright ambient light from a street light, the illuminator still performs well, providing sufficient light for target identification.
The RovyVon GL4 Pro positions itself in the market as a budget-conscious option for night vision laser sights. To understand its competitive standing, let’s explore how it compares to some of its counterparts:
In conclusion, the RovyVon GL4 Pro is a compelling choice for users seeking an affordable night vision laser sight solution. While it may not compete with top-of-the-line options in every aspect, it delivers a well-rounded feature set that punches above its weight class in terms of affordability.
