Comparing the InfiRay RH25 vs RH25 v2: What's New and Improved?

When InfiRay first introduced the RICO MICRO 640 RH25, it set a new standard in the thermal imaging space, particularly in the market for handheld and helmet-mounted devices. This tiny yet versatile tool quickly gained favor among hunters, law enforcement, and outdoor enthusiasts for its incredible performance packed into a compact frame. The RH25 was groundbreaking with its advanced electro-optic capabilities, including onboard recording, high-definition AMOLED display, and an ultra-sensitive 640x512, 12 μm sensor that delivered a class-leading thermal image.

Now, InfiRay has released an upgraded version, the RH25 v2, and while it retains much of what made the original version exceptional, it introduces significant improvements across the board. In this comparison, we’ll explore the differences between the RH25 and the new RH25 v2, helping you decide if the upgrade is worth it.

Performance and Sensor Enhancements

One of the most important aspects of a thermal monocular is its sensor, as this component determines the quality of the thermal image, the detection range, and the sensitivity of the device.

• RH25: The original version uses InfiRay’s 640x512, 12 μm sensor, which is more than capable of capturing high-quality thermal images. Paired with MATRIX III processing and a manual-focus f/1.0 lens, the RH25 delivers excellent image clarity at ranges up to 1375 yards.

• RH25 v2: The new RH25 v2 takes sensor performance up a notch. While specific details about the new sensor technology haven't been disclosed, what stands out is its drastically improved E value—from 40 in the original version to an impressively low value of less than 15. This change means that the v2 model is much more sensitive to thermal variations, which translates to crisper images and better performance, particularly in challenging conditions. Furthermore, the sensor resolution has been increased to 1440x1080p, offering users a higher level of detail and precision in thermal imaging.

Refresh Rate

A smooth and responsive refresh rate can make all the difference in real-time applications such as tracking fast-moving targets or navigating complex environments.

• RH25: The original version has a 50 Hz refresh rate, which provides smooth video output and is ideal for most users.
• RH25 v2: InfiRay has bumped this up to 60 Hz in the v2 model. While the difference may seem minor on paper, the increased refresh rate delivers smoother video performance, especially during high-speed movements. This enhancement will be particularly noticeable for professionals in law enforcement or military applications, where split-second decisions are crucial.

Display and Eyepiece Improvements

• RH25: The original RH25 features a 1024x768 AMOLED display, which provides sharp and vibrant images. The eyepiece has a diameter of 17 mm, which is fairly standard for thermal monoculars of this size.
• RH25 v2: In the v2 version, InfiRay has gone all out on display and eyepiece improvements. The new 1440x1080p resolution means users get sharper, more detailed images, and the eyepiece diameter has been increased to 20 mm. The larger eyepiece provides a more immersive viewing experience, making it easier to scan and observe your surroundings without straining your eye.

Weight and Ergonomics

When using a device like this for extended periods—whether in handheld mode or mounted on a helmet—weight and ergonomics can significantly affect user comfort.

• RH25: Weighing in at 12.7 ounces, the RH25 was already one of the lightest thermal monoculars on the market, making it a go-to choice for those seeking portability and ease of use. The focus mechanism was manual, but it required a fair amount of dexterity.
• RH25 v2: The new version manages to shave off about 10% of the weight, making it even lighter and more convenient for extended use. In addition to the weight reduction, the ergonomics have been improved with an enhanced focus system. The RH25 v2 now includes an added lever to make focusing easier, allowing for faster and more precise adjustments, even while wearing gloves or in low-light conditions.

Battery Life and Charging

• RH25: Battery life in the original RH25 was decent, offering around 4 hours of run time with its 18650 rechargeable battery. However, its charging system used an older style of connector that was not as user-friendly.
• RH25 v2: The new model introduces USB-C charging, a much-welcome modern upgrade that allows for faster and more convenient recharging. The RH25 v2 also extends battery life by an extra hour, providing up to 5 hours of runtime. This improvement is especially beneficial for users out on long hunts or missions where every bit of battery life counts.

Recording and Connectivity Features

• RH25: The RH25 was one of the first helmet-mounted thermal monoculars to offer onboard video and image recording, with a storage capacity of 64 GB. The recorded footage could be reviewed on the device’s AMOLED screen or transferred to another device.
• RH25 v2: One of the standout new features in the RH25 v2 is recoil-activated video and audio recording. This feature automatically starts recording when the device detects the recoil from a fired weapon, ensuring you capture every critical moment without needing to press any buttons. The addition of audio recording is another bonus, adding more context to your footage.

Mounting and Accessories

• RH25: The original version was compatible with standard dovetail helmet mounts and Picatinny rails, providing versatility in how it could be used.

• RH25 v2: InfiRay has retained the same footprint and platform for mounting but now includes a quick-detach (QD) mount as part of the package. This is a significant upgrade for users who frequently need to remove and reattach their monocular to different devices. The inclusion of a hard case in the v2 packaging is also a nice touch, offering better protection during transport and storage.

Pricing

• RH25: The original RH25 was priced around $3999, which placed it competitively in its market, given its wide array of features and capabilities.
• RH25 v2: The new RH25 v2 is priced between $4000 and $5000, depending on the package and configuration. While this represents a price increase, the improvements in image quality, sensor sensitivity, battery life, and recording features easily justify the added cost for those who need the best in thermal imaging technology.

Conclusion: Is the Upgrade Worth It?

The RH25 v2 represents a considerable leap forward in thermal imaging technology, and for most users, the upgrade will be well worth the investment. The enhanced sensor sensitivity, improved refresh rate, higher resolution, and new recoil-activated recording feature alone make the RH25 v2 an appealing option for anyone in need of top-tier performance.

For those who already own the original RH25, the decision to upgrade will largely depend on how often you use the monocular and in what conditions. If you frequently operate in demanding environments where every bit of image quality and performance matters, the v2 is a solid choice. If, however, you’re happy with the original RH25 and don’t find yourself pushing its capabilities to the limit, you may find that the original model still serves you well for years to come.

Ultimately, both models are outstanding, but the RH25 v2 brings new features and refinements that elevate it to a class of its own.
