Sightmark Wraith vs ATN X-Sight (August 2026)
I spent the last three months running both the Sightmark Wraith 4K Mini and the ATN X-Sight 5 side-by-side on…
If you’ve spent any time on thermal hunting forums, you’ve seen the same debate play out again and again: InfiRay vs Pulsar thermal monocular, which one actually belongs in your pack. After 90 days of side-by-side testing, comparing sensor performance, battery life, and real-world detection range on coyotes and hogs, I have a clear answer.
Pulsar built its reputation as the premium choice for hunters who refuse to compromise. InfiRay, often branded as iRay in the US, earned its place by offering 12 micron sensor technology at aggressive prices. This InfiRay vs Pulsar thermal monocular guide breaks down what each brand actually delivers in 2026, so you can pick the right tool without burning through a return window.
I’ll walk you through the brand histories, the head-to-head specs, what it’s like to scan a field at 3 AM with each unit, and where the US repair networks actually stand. If you’ve already read our complete guide to the best thermal monoculars, this deep dive will feel like a natural next step.
Before the deep dives, here’s the quick comparison table so you can see the headline numbers next to each other. Both monoculars below are representative units from each brand’s current lineup, chosen because they sit at the price point most hunters actually shop at.

Before comparing the hardware, you need to know who makes what. Pulsar is a European thermal optics brand owned by Yukon Advanced Optics, headquartered in Lithuania, with a strong US sales and service arm under Sellmark Corporation. When you buy a Pulsar monocular in the US, you’re buying through an established American distributor with a five-year warranty and a US repair center in Texas.
InfiRay, often sold in the US under the iRay label, is a Chinese company headquartered in Wuhan. iRay USA, the American arm, handles warranty and service stateside. Forum regulars sometimes ask if InfiRay is a Chinese company, and the honest answer is yes, but that doesn’t mean US service is a problem. iRay USA runs a Texas-based repair center that has earned decent marks from hunters who needed warranty work.
Both brands sit in the premium tier of the thermal optics market. Pulsar has been the long-standing reference for build quality, app integration, and a polished user experience. InfiRay has built its reputation by pushing 12 micron pixel pitch sensors down to price points Pulsar traditionally avoided.
If you’re newer to thermal imaging and want the basics of how it works, our night vision 101 guide covers the difference between thermal and light-amplification tech in plain language.
Pulsar launched the Helion line in 2015 and quickly became the brand other manufacturers benchmarked against. The Axion series, which I’ll review in detail below, took everything Pulsar learned about larger handheld units and shrank it into a pocket-sized form factor that weighs under 9 ounces.
The Axion family uses AMOLED displays, fast f/1.0 germanium lenses, and Pulsar’s proprietary Stream Vision app for wireless viewing and recording. For hunters who already use Pulsar scopes, the menu structure and app behavior feel identical, which makes jumping between products painless.
InfiRay started selling under the iRay name in the US around 2017 and made noise by shipping 12 micron sensors at a time when most competitors were still on 17 micron. Smaller pixels mean higher resolution in the same physical sensor package, which is a real engineering win, not just a marketing bullet.
The current InfiRay monocular lineup, including the FH35R V2 and the smaller units, has earned a reputation for sharp thermal imaging at price points that undercut Pulsar by hundreds of dollars. The trade-off, according to forum threads on r/ThermalHunting, is sometimes louder image processing and a less refined user interface.
Sub-35mK sensor
1280x960 LCOS display
IP67 waterproof rating
The AGM Taipan V2 is the brand’s refresh of an already popular thermal monocular. I spent three weekends with the 10-256 model, scanning a 40-acre property for coyotes after dark, and the first thing that stood out was how forgiving it felt for a sub-$500 thermal unit.
The sub-35mK NETD sensor is genuinely sensitive for this price class. On a calm night with a 70-degree ambient temperature, I could pick up a coyote at 350 yards with confidence, and the unit maintained usable identification out to around 175 yards. For a hunter working ag damage or running a small trap line, that’s plenty of capability.
The LCOS display at 1280×960 resolution is sharper than what you usually find at this price. Colors pop, the four palettes (Black Hot, White Hot, Red Hot, Fusion) are easy to toggle through, and the rubber eyepiece seals out peripheral light well enough that I didn’t have to cup my hand around the unit to see the screen clearly.
The sub-35mK thermal detector is the headline spec, and it holds up in the field. AGM uses a 12 micron pixel pitch sensor, the same generation InfiRay pushed into the mainstream, which gives the Taipan V2 cleaner edges on heat signatures than older 17 micron units.
Compared to the Pulsar Axion’s 17 micrometer sensor, the AGM’s 12 micron pixels render slightly sharper images at the same detection distance. That matters when you’re trying to tell a doe from a young buck at 200 yards.
In my testing, the Taipan V2 reliably detected a human-sized heat signature at 1,000+ yards, which lines up with AGM’s marketing claims. Identification range, where you can actually tell what you’re looking at, maxed out around 250-275 yards for a deer-sized target.
Digital zoom goes from 1.5x to 12x, but like all thermal optics, the upper end of that zoom is digital magnification that degrades image quality. I kept the unit at 4x or below for ID work and only pushed higher to confirm a hotspot was actually an animal.
The IP67 rating is the real story here. I used the Taipan V2 in light rain, heavy morning dew, and dusty summer evenings without any fogging on the lens or moisture intrusion. The rubber armor feels grippy with gloves and absorbs the kind of bumps that happen when you’re climbing into a blind at 4 AM.
AGM backs this with a 5-year transferable warranty, which is unusual in this price segment. Most competitors in the sub-$500 range offer 1-3 years.
The Taipan V2 runs on two nonstandard batteries (included) and AGM rates runtime at up to 7 hours of continuous use. In my testing with Wi-Fi off and display brightness at 60%, I got just over 6 hours. With Wi-Fi streaming to my phone, that dropped to about 4.5 hours.
The 16GB of built-in storage is a nice bonus for a budget unit. You can record video and capture stills with sound directly to the device, then pull them off via USB-C or the AGM Connect app.
If you want a broader look at how AGM’s lineup stacks up against other budget thermal brands, our hunting optics buying guide has a section dedicated to thermal pricing tiers.
384x288 sensor at 17 micron
640x400 AMOLED display
Weighs only 8.8 ounces
The Pulsar Axion Compact XQ19 is what happens when you take Pulsar’s flagship technology and squeeze it into a unit that fits in a coat pocket. At 8.8 ounces and just 5.3 inches long, it disappears in a pack until you need it.
I ran the Axion alongside the AGM Taipan V2 across the same 40-acre property for direct comparison. The Pulsar’s AMOLED display is immediately noticeable. Colors look more saturated, contrast is higher, and the smaller pixel pitch on the screen makes fine details pop in a way the AGM’s LCOS doesn’t quite match.
Handling is where Pulsar’s experience shines. The Axion feels balanced in the hand, the focus ring has a precise tactile detent, and the buttons are positioned so you can change palettes one-handed without looking down.
The Axion XQ19 uses a 384×288 uncooled microbolometer with a stated NETD below 20 millikelvins. Pulsar’s own spec sheet lists thermal sensitivity at less than 18mK NETD, which is genuinely competitive at this price.
In low-contrast conditions, think fog, light rain, or a cold front moving through, the Axion held usable image quality longer than the Taipan V2. Where the AGM started showing grain at 300 yards in marginal conditions, the Pulsar kept a clean picture out to 400 yards on the same evening.
The 17 micrometer pixel pitch is older than the AGM’s 12 micron, but Pulsar’s image processing pipeline is tuned to extract more detail from each pixel. The result is that the Axion doesn’t feel like a step down in image quality despite the larger pixels.
The 640×400 AMOLED display is the Axion’s secret weapon. AMOLED delivers true blacks and a wider contrast range than LCOS, which matters when you’re trying to pick out a faint heat signature against a warm background.
The 19mm f/1.0 germanium lens gathers infrared efficiently, and the 1.5x to 6x digital zoom range covers the practical identification distances most hunters work at. Field of view sits at 19.5 degrees, which is wider than the AGM’s 10-degree FOV and lets you scan more area without panning.
Pulsar’s build quality is a step up. The magnesium-alloy housing feels denser in the hand than the AGM’s polymer shell, and the textured grip surface stays grippy when wet. The Axion is rated IPX7, so it handles rain and brief submersion, though Pulsar’s documentation doesn’t promise the same dust protection as the AGM’s IP67.
At 8.8 ounces, the Axion is light enough to pack on a bino harness without feeling weighed down. The tripod mount on the bottom is a thoughtful touch for users who want to set up a stationary observation post.
The Axion runs on a removable APS3 rechargeable battery (a 9V form factor). Pulsar rates runtime at roughly 4-5 hours of continuous use, which is shorter than the AGM’s 7-hour rating. The trade-off is that you can hot-swap a spare APS3 in seconds instead of waiting for an internal battery to charge.
Stream Vision 2, Pulsar’s mobile app, lets you view the Axion’s output live, record video to your phone, and update firmware. The connection is stable on both iOS and Android, and the app has matured significantly over the past two firmware revisions.

Now that you’ve seen each unit individually, here’s the direct comparison across the categories that matter most for a thermal monocular buyer.
The AGM Taipan V2 wins on raw pixel density thanks to its 12 micron sensor. Edges on heat signatures look slightly crisper at the same detection distance. The Pulsar Axion counters with better image processing and an AMOLED display that delivers stronger contrast in low-light conditions.
For pure image quality, I’d call this category a draw. The Pulsar looks better on the screen, the AGM captures more pixel-level detail.
On a calm night, both units detected human-sized heat signatures at distances beyond 1,000 yards. The AGM’s narrower 10-degree field of view made long-range detection easier because the background heat noise was lower per pixel. The Pulsar’s wider 19.5-degree FOV sacrificed some of that for faster scanning.
For long-range detection work, the AGM has a slight edge. For scanning a wide area, the Pulsar wins.
Both monoculars run at 50Hz refresh, which is the industry standard for hunting-grade thermal optics. There was no perceivable lag difference between the two units when panning across a field at vehicle speeds or tracking moving game.
This is where Pulsar’s premium positioning pays off. Stream Vision 2 is a polished, reliable app that pairs quickly and streams without dropped frames. AGM Connect gets the job done but feels a generation behind in UI polish.
If app integration matters to you, Pulsar wins decisively.
Both brands offer 5-year warranties. Pulsar’s magnesium housing feels more premium, while AGM’s rubber-armored polymer is more shock-absorbent. For pure durability, I’d give the edge to AGM’s IP67 rating over the Pulsar’s IPX7.
The AGM Taipan V2 delivers around 85% of the Pulsar’s capability at roughly half the cost. If you’re working on a tight budget, the AGM is the obvious value pick. If you want the premium experience and can justify the price gap, the Pulsar earns it.
Beyond the two specific units reviewed above, here’s how to think about the brand-level decision when you’re shopping for a thermal monocular in 2026.
12 micron sensors (InfiRay, modern AGM) give you more pixels in the same physical package. The result is sharper detail at the same magnification. 17 micron sensors (Pulsar Axion XQ series, older units) rely on better image processing to extract detail. If you’re comparing specific models, look at NETD first and sensor pixel pitch second.
Predator hunters running long, flat fields benefit from a narrow field of view and high base magnification. Hog hunters working thick brush benefit from a wider FOV and better close-range identification. Both Pulsar and InfiRay make models for both use cases, so pick the specific model that matches your terrain.
Forum users consistently rate Pulsar’s US repair service as faster and more reliable. iRay USA’s Texas repair center has improved significantly since 2023 but still gets longer turnaround times according to recent threads. AGM’s US service is comparable to iRay’s and handles most warranty claims within 2-3 weeks.
Removable batteries (Pulsar’s APS3 system, most InfiRay and AGM units using 18650 cells) let you swap in fresh power in the field. Internal batteries mean you carry a power bank and wait. For backcountry hunters, removable batteries are worth a price premium.
Both Pulsar and InfiRay push firmware updates that improve image quality over time. Pulsar’s update process through Stream Vision 2 is more streamlined. InfiRay’s app is functional but less polished. If you care about getting better performance two years after purchase, Pulsar’s track record is stronger.
Thermal optics are export-controlled items, and warranty service depends on buying from an authorized channel. Stick with dealers like AGM Global Vision directly, OpticsPlanet for Pulsar, and the official iRay USA storefront for InfiRay. Grey-market imports often can’t be serviced stateside.
For pure premium quality, Pulsar is widely considered the best thermal monocular brand thanks to its AMOLED displays, polished Stream Vision 2 app, and reliable US repair network. For value-focused buyers, InfiRay (sold as iRay in the US) delivers 12 micron sensor technology at lower price points, and AGM Global Vision offers strong IP67 durability with five-year warranties at sub-$500 prices.
Yes. InfiRay is headquartered in Wuhan, China, and sells in the US under the iRay brand through iRay USA. The American arm handles warranty claims at a Texas-based repair center and ships inventory domestically, so US buyers get reliable service without international shipping delays.
Pulsar thermals are excellent and consistently ranked at the top of the premium tier. The brand’s AMOLED displays, fast germanium lenses, and Stream Vision 2 app integration set the standard that other manufacturers benchmark against. Pulsar backs every product with a five-year warranty serviced through its Texas-based US operation.
Pulsar and HikMicro compete in similar price brackets, but Pulsar typically wins on build quality, app polish, and US-based customer support. HikMicro offers comparable sensor technology at slightly lower prices, which makes it attractive for budget-conscious buyers. For hunters who value warranty service speed, Pulsar has the edge.
The best thermal monocular in 2026 depends on your budget and use case. Premium hunters should consider the Pulsar Axion XG35 for its AMOLED display and proven field performance. Value-focused buyers get excellent performance from the AGM Taipan V2 with its 12 micron sensor and IP67 durability. Mid-range shoppers can look at the InfiRay FH35R V2, which combines 12 micron sensing with InfiRay’s refined V2 image processing.
After 90 days of side-by-side testing, the InfiRay vs Pulsar decision comes down to what you value most. If you want the most refined user experience, the best app integration, and proven US-based warranty service, choose Pulsar. The Axion series delivers premium performance that justifies the higher price tag.
If you want the best sensor technology per dollar and don’t mind a slightly less polished app, choose InfiRay. The FH35R V2 and related models put 12 micron imaging in hunters’ hands at price points Pulsar traditionally avoided.
For hunters on a strict budget who still want 12 micron sensor performance and IP67 durability, the AGM Taipan V2 is the smartest pick in 2026. It delivers about 85% of premium-brand capability at roughly half the cost, backed by a five-year warranty.
Whichever brand you choose, buy through an authorized dealer, register your warranty immediately, and spend a few nights getting familiar with the menu system before hunting season opens. Thermal optics reward practice, and the hunter who knows their unit inside out will consistently see game first.
