Compact Spotters and the Sweet Spot in the Lineup 

Compact spotters prioritize mobility and simplicity 

Compact spotters remain the darlings of hunters who want minimal weight and maximum mobility. Their small housings, pocket-friendly size, and now genuinely ergonomic operation make them easy to carry on long outings. 

• Lightweight and portable for extended use in the field 

• Ergonomic controls allow fast, one-handed deployment 

• Ideal for mobile hunters or scanning on the move 

The newly released Axion XQ19 Compact embodies this class perfectly — light, quick to deploy, and delivering solid thermal performance without overcomplication. 

Field Perspective: A compact thermal that goes everywhere 

We asked Peter Gibbon, a seasoned hunter from the UK, for his take on the newest compact monocular: 

I have been using the Axion XG35 Compact for a few months now and it is a super capable little compact unit that fits in your hand, pocket or bag. It is easy to use and has a great battery life. It is perfect for identification of animals when I am out on the hunt or even just scanning to the ground to check for any signs of life. Its compact size means you are not worried about carrying something bulky about. It’s my go-to device if I am on the go these days.

Oryx offers mid-size thermal performance without the weight of full-size systems 

For those wanting more reach, larger optics, and an integrated rangefinder without stepping up to the full-sized Telos platform, the Oryx sits in the sweet spot. 

• Bridges the gap between compact monoculars and full-sized systems 

• Delivers professional-grade thermal performance 

• Maintains true one-handed operation in a compact form factor 

Full-Sized Monoculars for Maximum Performance 

Larger optics and more power for demanding hunters 

Stepping up in size, full-sized thermal monoculars bring the advantages of: 

• Larger lenses for enhanced image quality 

• Bigger batteries for extended runtime 

• More processing power for smoother performance 

This class also comes with a corresponding bump in price and weight, but it’s ideal for those who prioritise top-tier thermal clarity, long-session reliability, and upgrade potential. 

Telos series: Field-tested performance and future-proofing 

Pulsar’s Telos series stands out in this category — not just for optics, but for its hardware upgrade system that lets owners: 

• Replace sensors 

• Swap lenses 

• Add a rangefinder after purchase 

This future-ready design is ideal for hunters who want long-term value from their investment. 

Field Perspective: A seasoned hunter’s take on Telos 

Peter Gibbon, a long-time thermal user and early adopter, shares why Telos is his current favorite: 

The Telos is my work horse, and it is perfect. I currently use the LRF XG50 model, which gives me an intermediate sensor with a great field of view and longer range of detection.

The new Green colour palette has made this device so much better. This unit is bigger with its design, but battery life is good and the ergonomics work well.

It is a two-handed operation but coming from an old Quantum HD50S, this isn’t a problem. The image quality is extremely good.

The fact the unit has the ability to be upgraded in the future really is a plus point for me — if I decide I want a better sensor, I can arrange to do this without the need to buy a new device.

Peter Gibbon’s daily-use experience with Telos LRF XG50

We’ve already noted that Peter Gibbon uses one of the Telos monoculars almost daily. Here’s how he describes it in practice:

The Telos LRF XG50 is an excellent tool. It has a higher base magnification but when you use it for foxing or identifying deer at a longer distance, this is just perfect.

If I needed to do more close-up and detailed work, I would probably choose an XP or XL, but I feel for the work I do, it is a great value unit that will last a long time.

Base Models

(All models are available with or without a built-in LRF; specifications below refer to the base units.)

Personal tip from Christian: For long night stalking with a thermal spotter, I have been running the Telos LRF XP50 since it hit the market. It features a 50 mm F1.0 lens paired with a 640×480 @ 17 µm sensor to deliver exceptional thermal sensitivity that still today beats all other spotters with equal sensor size on the market.

Base magnification of 2.5× provides a generous 21.8 meter field of view at 100 meters for great situational awareness and good details. The 1024×768-pixel AMOLED display gives sharp image details even with low light settings for pitch darkness settings.

Understanding Pulsar’s model naming

Pulsar’s model codes provide a quick way to understand the intended performance of each unit.

• XQ models use a 384×288 sensor with a 17 µm pixel pitch. They deliver mid-level performance, offering a balance between cost and image quality, with a moderate field of view suited for general-purpose scanning.
• XG models feature a 640×480 sensor with a 12 µm pixel pitch. They offer higher resolution and finer detail at longer ranges, with a slightly narrower field of view than XQ models when using the same lens size.
• XP models also use a 640×480 sensor but with a 17 µm pixel pitch and higher thermal sensitivity. This makes them perform better in fog and wet conditions, and they provide a wider field of view than XG models with the same lens size.
• XL models carry a 1024×768 sensor with a 12 µm pixel pitch. They deliver HD resolution for extreme detail at long range, but have the narrowest field of view, optimised for distant target work.

Expert note: “Sensor choice is a very personal thing – sometimes, bigger is not always better. Everyone’s use of thermal is different: if you require a thermal to make fine detail identification, you will need an XL unit. However, if you are just trying to spot something, the XQ sensor will do perfectly. The XG and XP sensors offer a great identification and valve.” – Peter Gibbon, a hunter from the UK with 25+ years of experience.

Lens focal length — shown by the number in the model name — further defines performance. Larger lenses (e.g., 50 mm) give a narrower but more detailed view at long range, while smaller lenses (e.g., 19–35 mm) offer a wider field of view for scanning and close-to-medium range spotting.

Personal tip from Christian: When comparing thermal spotters across brands, models, lenses, and sensors, the single most useful figure for me is the horizontal field of view (HFOV) at 100 metres. This tells you exactly how much landscape you can see in a single glance — a far more meaningful measure than a long list of lens and magnification specs.

Once you know the HFOV, consider the sensor size: a larger sensor allows you to zoom in digitally while keeping more detail. For most of my own hunting, the thermal spotter is for the initial detection of game and rough species guessing — the fine identification work, such as gender and age, I leave to the riflescope, where a lower HFOV is preferable.

• The terrain you operate in
• How you balance features vs cost

Before committing to a purchase, it’s worth considering a few key factors.

1. Match the monocular to your hunting environment

Assess your primary terrain and target species:

• In dense woodland or mixed farmland, go for a shorter focal length (19–35 mm)
  • Offers wider field of view for tracking moving game up close
• In open landscapes like fields or valleys, a 50 mm lens offers more detail at distance
  • Ideal for foxes, wild boar, or deer often spotted across large areas

2. Consider your budget and key features

Thermal monoculars range from affordable entry-level models to high-resolution, full-featured systems.

Ask yourself:

• Do you need maximum detection range?
• Is image clarity your top priority?
• Do you want a built-in rangefinder?
• Will you be out for long sessions needing extended battery life?

Examples:

• Axion XQ19 Compact: Core thermal features at an accessible price
• Telos XP50 / XL50: High-end sensors, advanced optics, and modular upgrades

3. Ergonomics and field usability matter

A technically capable monocular that’s awkward to use will cost you critical moments.

Look for:

• True one-handed operation
• Intuitive controls and focus mechanisms
• Balanced weight and compact design

The Oryx LRF stands out with a rear-mounted focus wheel — ideal for single-handed adjustments during active stalks.

4. Future-proof your investment

Thermal technology moves fast — your investment doesn’t have to be left behind.

Pulsar’s Telos series offers:

• Sensor upgrades

This ensures your device evolves with your needs and Pulsar’s advancements.

Expert Advice: Buy for your needs, not just specs

When choosing the right device, it is not always about buying the biggest and most expensive unit.

Find the device that suits your needs. If you need super fine detail, go for the XL sensor.

If you need a general workhorse for finding game, a midrange sensor will do perfectly.

Budget can also be an issue — but with upgradeable units, you can buy what you can afford now and upgrade later.

I’ve had a Pulsar unit for over 10 years. The build quality is excellent, so you won’t have to worry about it falling apart.

Dive Deeper: How To Choose The Right Thermal Imaging Monocular for your needs

A shifting market in 2025 

In 2025, the thermal monocular market has matured into two distinct but closely related categories: ultra-compact spotters and full-sized monoculars.  

Across both, there’s a clear shift towards true one-handed operation — not just for menu navigation but also for fine focus adjustment. This means hunters can now operate their thermal without juggling grip and focus, making long stalks and quick observations far more practical. 

The integrated laser rangefinder, once awkwardly placed for left-handed users, is now almost universally mounted beneath the lens, improving balance and accessibility for all shooters.  

While each major manufacturer still brings its own quirks and refinements, the overall direction is towards a more uniform, user-friendly form factor — and that’s good news for anyone in the market for a new thermal.

Performance Trends and Pulsar’s Position 

Sensor specs are converging, but trade-offs remain 

On paper, most manufacturers now offer similar 640×480 thermal sensors and increasingly sophisticated image-processing algorithms. 

While higher-resolution sensors like 1024×768 and 1280×1024 are available, they typically introduce real-world compromises: 

• Reduced thermal sensitivity in marginal conditions 

• Heavier processing loads, impacting image smoothness 

• Shorter battery life, especially during extended use 

Pulsar maintains a lead through refinement and reliability 

Pulsar continues to stand out, especially through its balance of performance and field-tested reliability. 

• The XP50 model, for example, still outperforms many newer competitors 

• It uses a 17 µm pixel pitch sensor — a design that has remained competitive for years thanks to Pulsar’s continual software and processing improvements 

Pulsar Tip: Newer isn’t always better — refinement often trumps raw specs in real-world hunting conditions. 

My Final Thoughts

When hunters ask me about the best thermal monoculars, I always say it depends on what “best” means for your hunting style. Some of us prioritize compact size and portability, others need detection range and sensor resolution, while professionals often look for long-term upgradeability. In other words, there isn’t one single answer — the right choice is the one that matches your terrain, your target species, and your personal priorities.

From my experience, Pulsar’s 2025 thermal monocular range really does cover the full spectrum — from the pocket-ready Axion Compact, to the one-handed, all-round Oryx, to the modular, future-proof Telos. Each series reflects a clear market shift toward ergonomics, integrated rangefinding, and high-sensitivity sensors designed for real hunting conditions.

Which one is best for you?

Choosing between them comes down to your terrain, your target species, and how much you prioritise features like:

• Upgradeability
• Sensor resolution
• Weight and portability
• Field durability
• Rangefinding capability

If you need a compact companion for every stalk, the Axion Compact is hard to beat — offering essential performance in a jacket-pocket format.

If you’re looking for professional-grade thermal performance in a lightweight, single-handed device, the Oryx offers a well-rounded, field-proven option.

And if you want the last monocular you’ll ever need to buy, the Telos — with its sensor and lens upgrade path, modular design, and premium features — is the obvious long-term choice.

Ready for any terrain in 2025

Whatever you choose, I can vouch for Pulsar’s combination of European engineering, proven LYNRED sensors, and hunter-focused design — every model in this lineup is built for the realities of the field, in 2025 and beyond.

FAQs

Can you use a thermal monocular for hunting?

Yes. Thermal monoculars are widely used by hunters for spotting game in low light, dense cover, and at night. They detect heat signatures rather than relying on visible light, making them effective in conditions where traditional optics fail.

What are some common uses for thermal monoculars?

Beyond hunting, they’re used for wildlife observation, search and rescue, security, property inspection, and pest control.

Are thermal monoculars worth it for hunting?

For many hunters, yes — especially in dense cover or at night. They can dramatically improve spotting efficiency, reduce missed opportunities, and aid in game recovery.

What magnification is best for a hunting thermal monocular?

Lower base magnifications (2–3×) with a wide field of view are ideal for scanning. Higher magnification helps at longer distances but narrows the view, which can make tracking moving game harder.

What to look for when buying a thermal monocular?

Key factors include sensor resolution, sNETD sensitivity, lens size, field of view, ergonomics, battery life, and whether it has an integrated rangefinder.

Why are thermal monoculars so expensive?

The cost comes from the advanced thermal sensors, high-grade optics, image-processing electronics, and durable weatherproof housing. Manufacturing is complex, and many components — especially high-sensitivity European sensors — are costly to produce.
