Versatility: What Defines the iRay RH25 V2

Versatility: What Defines the iRay RH25 V2

Feb 11th 2026

The iRay RH25 V2 is only one of dozens of thermal scopes out there; it’s not even the only strong choice from its own brand.

But its versatility is what makes it one of the best thermal optics on the market right now, as it stands. Here are a few things that just might make it the best.

Why It Might Be the Best

If you’re thinking the iRay RH25 V2 might be for you, here are some of its strongest selling points.

It’s a Thermal Scope

Naturally, you can mount the iRay RH25 V2 to your rail and use it as a dedicated thermal scope. With a 640x480 sensor resolution and a 12μm pixel pitch, a 15mK (or better) NETD rating and a 60Hz frame rate, the RH25 V2 is sensitive, produces a sharp, clear sight picture with minimal lag, and is super fast. It rapid target acquisition, identification, and shot placement.

It also offers 7 different reticle types in 4 different colors and supports 7 color palettes for the display, too, so it’s fairly versatile as a thermal scope.

Though it doesn’t have a ballistic calculator, like many other high end thermal rifle scopes, it does offer recoil-activated video and plenty of other capabilities to support your nocturnal hunts. There might be other better thermal scopes for your use, but for one thermal optic that can pretty much do it all, it’s a solid pick, and there are few if any that are as versatile.

On that note:

It’s a Thermal Scanner

The iRay RH25 V2 is not just a thermal rifle scope. You can also use it as a handheld thermal scanner, much in the same way as you’d use a thermal monocular. And, if you have a conventional optic on your rail, you could take the RH25 off your rail and use it as a scanner (more on the former point in a second).

Because of its small size, compact form factor, and lightweight design, you can easily stash this thing in a pocket or a pack compartment, easily, and forget it till you need it. The multiple color palettes it supports will also help you prevent the night blindness that can occur when using a thermal scope - for instance, red is a good palette for this.

The long detection range is another bonus. It can detect thermal signatures as far off as 1375 yards, which is not quite a mile, but close. This makes it ideal for scouting and tracking, especially of wary predators and other targets that might be leery about closing the gap.

As you would expect (and justifiably) from a thermal scanner, the iRay RH25 V2 is also built tough. With an operating temperature range from -4℉ to 122℉, it’s more than equipped to hang with you through long, frozen nighttime hunts and muggy summer evenings chasing hogs in bottomlands. It also offers an IP rating of IP67, making it fully waterproof in the rain, ensuring that it is well equipped to stand up to the most unforgiving environmental conditions.

It’s a Clip-on Thermal Optic

One of the best things about the iRay RH25 V2 is the form factor, which enables it to be used as a clip-on thermal scope. What this means for you is that if you already have a scope on your rifle that’s sighted in, and you don’t want to swap it, a thermal clip-on like the RH25 V2 just might be the best option at your disposal.

The small size and form factor of the RH25 V2 enables you to mount it to the rail in front of your standard scope; by viewing the sight picture produced by the RH25 V2 through your scope, you can effectively retrofit thermal capabilities to it, converting your current scope setup into a thermal optic.

This is great for anyone that appreciates their current scope or who does not want to remove and replace the scope, which would require additional sight in. By running a clip-on thermal optic, you get the best of both worlds - and you can remove it during the day for shooting under normal ambient light conditions, equipping your rifle for multiple sporting roles.

So with the RH25 V2, you get multiple different thermal optics effectively for the price of one. Also, for what it’s worth, this iRay thermal scope can also be helmet-mounted.

Price

The iRay RH25 V2, like all quality thermal optics, is not cheap. But even though that may be the case, it is still competitively priced considering how much versatility it offers, which is yet another selling point.

What’s New in the iRay RH25 V2?

For what it’s worth, iRay has made some improvements to the RH25 V2. Among these are:

  • Both the RL25 and RH25 V2 optics can be used as clip-on thermal optics, a feature that was previously only available in the RH25.
  • The RH25 has a larger eyepiece as well as a larger display, providing a significantly larger viewing area and more pixels.

In addition, the RH25 V2:

  • Features a compact 3-button control panel that is easy and intuitive to find and engage, even in the dark.
  • Is powered by a rechargeable, replaceable battery.
  • Features a new, lighter, machined magnesium alloy body that trims down slightly on weight.
  • Offers 64GB of internal storage so you can capture and store photo and video onboard.

This is just a snapshot into the features and functionality of this extremely versatile thermal optic from iRay. There are others; for a more detailed breakdown, check out the iRay RH25 V2 on our website or get in touch with us directly.
