Use Cases

One of the great things about the iRay RH25 V2, in addition to the fact that it can be mounted and run so many different ways, is the sheer number of applications it supports.

  • Hunting: The iRay RH25 V2 is a great scope for nocturnal hunting and can be used for coyote, fox, and hog hunting, as well as for furbearers and other predators. High resolution paired with a fast frame rate ensures crystal clear thermal signatures and no lag time for fast thermal signal detection and positive target identification.
  • Wildlife observation: Scouting and scanning are two other practical use cases for the RH25 V2, and it makes a solid thermal monocular for wildlife observation and management.
  • Surveillance and security uses: The 1375-yard detection range of this thermal scope makes it ideal for perimeter monitoring and long-range surveillance of facilities and grounds.
  • Law enforcement, search and rescue: Search and rescue personnel often rely on thermal signatures to identify missing persons, saving vital time. Even in tough environments, the high-resolution sensor of the RH25 delivers.

What Else Makes the iRay RH25 V2 a Great Thermal Scope

  • Advanced performance: The 640x480, 12μm thermal sensor, with a NETD rating of 15mK and a 60Hz frame rate ensure rapid target identification and smooth, lag-free viewing. Clear and detailed thermal display defines the RH25 V2, making it perfect for scouting, hunting, tracking, and much more.

  • Tough build: Upgraded with a tough magnesium alloy housing, the new RH25 V2 is also IP7 rated against moisture and dust intrusion, making it perfect for long, grueling nocturnal hunts in adverse conditions, through all seasons of the year. It also boasts a 1000g/s2 recoil rating, making it tough enough to withstand the shock of large calibers like .300 Winchester Magnum.
  • Compact size: Only 4.52”x2.55”x1.88” and just 11.3 ounces due to the lighter magnesium alloy housing, the iRay RH25 V2 is compact and lightweight, making it not only perfect as a thermal scope, but solid as a handheld thermal monocular.
  • Magnification options: With a digital magnification option of up to 4 times, the RH25 V2 is well-equipped to engage targets at both close and intermediate ranges.
  • Long detection range: Equipped with a detection range of 1375 yards, you can identify targets more than three-quarters of a mile away. This makes this thermal optic ideal as a scanner for scouting as well as a scope at the the close and intermediate ranges aforementioned.
  • User-friendliness: Lastly, this InfiRay thermal scope is packed with user-friendly features, including on-board recording, a wide field of view, and physical buttons that are easy to locate, identify, and utilize in the dark, even when wearing gloves.
