Key differences between Telos and Axion Compact
When comparing the Telos and Axion Compact series, the biggest differences come down to performance, upgradeability, size, and intended hunting style. Both offer strong thermal capabilities, but each excels in very different scenarios. Here’s how they diverge when you look at real-world use.
Telos – Top tier
Telos sits at the top of Pulsar’s thermal monocular hierarchy, combining premium imaging performance with an upgradeable platform and integrated LRF options.
- At the top of the range, the TELOS LRF XT50 uses a 1280×1024 @ 12 µm HD sensor and provides the widest field of view in the Telos lineup at 17.5°. This combination delivers maximum image information while allowing more terrain to remain visible during scanning.
- Other Telos models offer different specialist strengths: the XL50 remains a premium HD option for fine detail at longer distances, the XP50 prioritizes thermal sensitivity in difficult low-contrast conditions, while the XG50 offers higher base magnification for long-range observation.
- Across the Telos platform, fast optics, advanced image processing, professional ergonomics and upgradeability support demanding observation across varied terrain and conditions.
Axion Compact – small and practical
Axion Compact, on the other hand, focuses on rapid detection at practical distances.
- The Axion XG35’s 640×480 sensor with a 35 mm lens still delivers very good clarity up to ~1750 m, more than adequate for most European hunts.
- The Axion XQ19 Compact, while lower resolution, gives a wide field of view and excellent portability, providing the hunter with up to ~750 m detection range.
For many hunters in typical terrain, that is more than enough.
Both series offer outstanding detection, but Telos wins in the ability to be upgraded, image fidelity and consistency at digital zoom levels. Axion’s advantage lies in portability and responsiveness, it’s ready the moment you need it.
– Freya Askjaer
If you’d like to get a more detailed hunter’s overview, here are Julia’s thoughts:
Telos is perfect for those most demanding hunters who go out when all others stay at home as it still does its job even in heavy rain, snow or fog. It will be a very helpful tool for those who must do very specific individual selection while hunting as Telos’s image quality allows you to recognize even the small details. And then also those hunters who scan through very open terrain and take shots at longer distances will enjoy Telos as well, both because of the LRF availability and good image quality even on distant objects.
Axion Compact series is for those who need something tiny and light for making quick scanns of the terrain and who maybe have a scope for better detail recognition. It is also a device at a very friendly price level, so it is good for those who just want a helpful device for hunting, but do not need “cinematic” image quality. It is also a good device for hunters whose hunting grounds consist mostly of forested, dense areas.

Hunting scenarios – which model fits your style?
Terrain dictates the tool. In forests, Axion Compact wins every time. In wide farmland or mountain terrain, the Telos gives you the clarity and range advantage that smaller thermal optics can’t.
– Freya Askjaer
Woodland and driven hunting
The Axion Compact series is ideal for fast detection in dense areas, and short-to-mid range. If you choose the Axion XQ30 Pro Compact or even the smallest Axion XQ19 Compact, you will have a lightweight monocular for one-handed use during movement.
Open fields and long-range scouting
Here, the Telos series excels through its combination of image detail, detection range and model-specific optical configurations. The TELOS LRF XT50 is particularly suited to hunters who need to scan large open areas while retaining high image detail, combining a wide 17.5° field of view with HD resolution and integrated ranging. The XL50 remains particularly relevant when fine detail at longer distances is the priority, while the XG50 offers higher base magnification for long-range observation.
Mixed terrain and all-weather conditions
For mixed terrain, Telos offers a broader range of premium imaging configurations, allowing hunters to prioritize different needs. The TELOS LRF XT50 combines a wide scanning view with high image detail and integrated ranging, while the XP50 is particularly relevant when thermal sensitivity in low-contrast conditions is the priority. If compactness and fast deployment matter more, the Axion XG35 or XG30 Compact may be the more practical choice.
Mobile stalks and quick scans
The Axion Compact with its compact body and low weight, is fast to deploy and equipped with an adequate resolution and base magnification.
Static hunts
Go for the Telos XL50 with its large lens, high sensitivity, comfortable ergonomics and mount it on a tripod for long term use.
Julia also adds that Telos might be particularly useful for wild boar hunting:
When I am hunting wild boars at night, I need to be able to recognize the gender of observed animals. The image quality in Telos allows me to spot the characteristics on the body of the boars and distinguish between males, females and also about their age and roles in the group.
Thanks to that, I can make a good decision and harvest the right individuals.
Match your terrain and hunting style
For open or mixed terrain where wide-area scanning, high image detail and ranging are all important, consider the TELOS LRF XT50.
For long-range observation where fine detail or higher base magnification is the priority, consider the Telos XL50 or XG50 respectively.
For dense woodland, stalking or hunts where minimum size and weight matter most, Axion Compact – particularly the XQ19 or XG35 – is likely the more practical choice.

Think about upgradeability
If you want a device that evolves with you, the Telos is the only one with a true upgradable sensor and/or LRF unit.
If you prefer simplicity and fixed performance, Axion Compact gives you all you need immediately.
Evaluate your range needs
If your observations typically occur within 200-300 m, the Axion Compact line is already sufficient.
If you regularly scan beyond 500 m and want to identify details like antlers or selective shots, the Telos excels here.
Budget considerations
Telos is premium, expect a higher investment.
Axion Compact offers excellent value, leaving a budget for ammo or additional equipment.
Comfort and portability
If you carry your gear for miles, switch positions often, or move quickly, Axion Compact’s smaller form-factor offers clear advantages.
If you’re often stationary, using a tripod, or have the capacity to carry a little more weight, the Telos is the perfect choice.

- You have long observation sessions. The balanced weight and textured grip make them less fatiguing.If you need more help, Julia shares why she prefers Telos over Axion Compact:
I receive a very good, sharp and detailed image – which from practical perspective is the key. Plus, it has the LRF which is a super helpful and important tool. While hunting at night or in a hilly terrain your eyes can get fooled and the distance you guess can be actually something totally different… and that will affect the precision of your shot. So, for me LRF is almost like a must have feature while hunting.
Honestly, I also think the XP50 does all the job that XL does, too – you get good enough image in the XP50… and it is cheaper, but of course… the image in XL is crazy and “fancy” haha.
Choose Axion Compact if:
- You prefer a compact, affordable unit that you’ll carry everywhere. The lightweight body is suited for mobility and fast deployment. The small form factor is suitable for your jacket pocket, harness, or backpack strap.
- You do stalk hunts, hunt in woodland, or prioritize convenience and portability.
- You need strong image quality at typical stalking distances without the weight or cost of a flagship thermal device.
- You prefer a quick startup time, always ready to scan quickly when you are in stalking mode.
