InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular Review

First Impressions of InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular

The InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular promised to be a game-changer, a compact powerhouse blending thermal imaging with precise distance measurement. Coming from years of experience with various night vision and thermal optics, I was eager to see if this monocular could live up to the hype, especially given the increasingly critical role thermal technology plays in hunting, security, and search & rescue. The integrated laser rangefinder was particularly appealing, offering a potentially streamlined solution for target identification and ranging in low-light conditions.

I needed a reliable thermal monocular that could both detect heat signatures at a distance and accurately range targets. This capability is crucial for ethical hunting practices and effective property surveillance. I ultimately chose the InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular after researching several competing models from AGM and Pulsar, primarily due to the promise of its high-resolution 640×512 thermal sensor and integrated LRF in a compact form factor.

Unboxing the InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular, the initial impression was positive. The unit felt solid and well-built, with a comfortable weight and ergonomic design.

Compared to the Pulsar Axion Key XM30S, which I’ve also used, the InfiRay felt more substantial and featured the added benefit of a built-in LRF. My initial expectation was that the integrated LRF would make target ID faster and ranging more accurate. I was excited to take it into the field for some rigorous testing.

Real-World Testing: Putting InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular to the Test

First Use Experience

My first field test of the InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular took place during a nighttime hog hunt on a sprawling ranch in central Texas. The humidity was high, but the temperature was a comfortable 65 degrees Fahrenheit. Initial impressions were mixed.

The thermal imaging was impressive, easily detecting hogs at distances exceeding 500 yards, but navigating the menu was not immediately intuitive. The boot-up time was also noticeably slow, as mentioned by another user, clocking in at around 12 seconds.

Extended Use & Reliability

After several months of regular use, the InfiRay Outdoor Finder FH35R V2 2-4x35mm Thermal Laser Rangefinding Monocular has proven to be a reliable tool. I’ve subjected it to various conditions, including cold, rainy nights and dusty environments.

The IP67 water resistance rating has held up well, with the unit showing no signs of water damage even after being exposed to heavy rain. I clean the lens regularly with a microfiber cloth to maintain optimal image quality, and the housing has shown minimal wear and tear, a testament to its durable construction. It has not outperformed my expectations, because of the quirky software, but has not disappointed in terms of core thermal functionality.
