Expect clear, practical advice backed by Pulsar’s trusted approach to innovation and real-world testing — so you can make an informed, confident decision in your next thermal purchase.

Monoculars vs Binoculars: The Core Difference

A thermal monocular is a single-lens thermal optic that shows heat signatures through one eyepiece, allowing hunters to scan large areas quickly while on the move.

In comparison, a thermal binocular uses two eyepieces to provide a more immersive, comfortable viewing experience, sometimes with enhanced depth cues similar to how human vision naturally perceives distance. This stereoscopic effect — meaning a sense of three-dimensional depth — can help with judging distances and identifying targets more accurately during longer observation sessions.

In the field, monoculars are typically favored by stalk hunters who value fast scanning, thanks to their more compact design and lighter handling. Binoculars often suit stand hunters best, where extended, steady observation benefits from reduced eye fatigue and a more natural viewing style.

But don’t just take our word for it: take it from Freya Askjaer, a Danish huntress with hunting experience in various countries all over the world.

“While scouting for deer in the cold morning mist, I compared a thermal monocular to binoculars — and the difference was clear. The monocular was lightweight and quick to detect roe deer moving through dense cover, while the binoculars provided sharper detail and better depth perception in open fields.

In the forest, I preferred the monocular for its agility, but once I stepped into the open, the binoculars’ magnification and thermal clarity became invaluable — especially for spotting roe deer at greater distances.”

Pros and Cons of Thermal Monoculars

Thermal monoculars are versatile tools that allow hunters to quickly scan, detect, and track heat signatures with a single hand, making them well-suited for dynamic situations in the field. While they typically balance portability and price well, certain advanced models can be larger and more premium-priced.

Pros of Thermal Monoculars

Typically lightweight and easy to carry

Allow one-handed operation for better mobility

Simplify quick scanning during stalk hunting

Often more budget-friendly than binoculars

Broad product range, from compact to high-end options

Cons of Thermal Monoculars

Single-eye viewing may cause fatigue over long periods

Limited depth perception compared to binoculars

Can require frequent eye-switching to reduce strain

Advanced models (e.g., Telos LRF XL50) may lose the “compact” advantage

Real-Life Use Case

So, technicalities aside, in what real-life situations will a hunter benefit from a monocular like the Pulsar Axion XG35 Compact or Oryx LRF XG35? Here’s how our expert hunter Freya uses hers:

“Using the Pulsar thermal monocular fastened to my chest rig under the canopy of the forest at night, I was amazed — it consistently revealed critters moving through the brush and larger deer moving quietly around me. Its lightweight, hands‑free setup makes it a go‑to for any dusk or pre‑dawn outing.

The Axion is compact, instinctive to use, and perfect for scanning during slow stalking when the light is low and the terrain demands patience.”

Quick summary: If you hunt in dense brush or narrow paths, a monocular makes it easier to stay agile and maintain your line of sight without losing your shooting position.

Pros and Cons of Thermal Binoculars

Thermal binoculars provide a more natural, immersive viewing experience by engaging both eyes, which reduces fatigue and supports easier depth estimation during long observation periods. This makes them ideal for hunters who stay stationary, such as stand hunters.

Pros of Thermal Binoculars

More natural two-eye viewing experience

Reduced eye strain over prolonged use

Improved perception of distance and spatial awareness

Better suited for scanning wide open areas or stationary glassing

Increased comfort during extended hunting sessions

Cons of Thermal Binoculars

Typically heavier and bulkier than monoculars

Less convenient for one-handed use

Higher price points for premium features

May be less practical for dynamic stalk hunting

Real-Life Use Case

What exactly are the situations where observational comfort is more important than slightly heavier weight? One of them is stand hunting: when you’re monitoring large open meadows during dusk hours, the benefit from thermal binoculars like the Pulsar Merger LRF XP35 will be great. This model supports extended glassing with reduced eye fatigue, ensuring targets are clearly identified even in fading light.

For the Danish huntress Freya Askjaer, they’re irreplaceable in between seasons, too:

“During the pre-hunting season, one session in the wide, frost-coated fields of Jutland proved just how well the Pulsar thermal binoculars perform. When glassing a field or open area with little to no vegetation, they excelled — quickly detecting heat sources and helping me identify the type of animal I was seeing.

What struck me most — beyond the sharp thermal image — was the sheer comfort. The classic binocular design allowed me to glass for extended periods without eye strain or the one-sided fatigue I often get with a monocular. Where long, patient observation is key, the Merger’s ergonomic build made all the difference.”

Field Warning: Consider the added weight of binoculars if you plan to carry them for long distances on foot — they can become tiring without proper harness support.

Choosing the Right Device for Your Hunting Style

The best thermal device for you depends on your hunting method, the terrain, and how long you typically observe targets. Hunters who move frequently and value quick scanning often benefit from a monocular, while hunters who prefer steady, prolonged observation will generally find binoculars more comfortable and efficient.

Hunting Style Guidance

Stalk hunters in dense forests or mixed woodland usually gain more flexibility with a monocular, which supports rapid scanning and agile movement.

Stand hunters in open terrain or fields often prefer binoculars for their comfortable, immersive viewing experience during longer waits.

In transitional hunting (some movement, some stationary glassing), a higher-end monocular with advanced features like a built-in LRF can balance both needs.

Decision Shortcut

If you’re tracking on foot through a tight cover, a monocular usually fits best. If you hunt from a stand overlooking fields, binoculars are the better pick.

Seasonal & Experience Variations

Winter hunts: Binoculars can help distinguish subtle heat differences in snow-covered ground thanks to more comfortable long-duration viewing.

Beginner hunters: May prefer monoculars for simplicity, lower price points, and lighter handling.

Expert hunters: Often appreciate the immersive experience of binoculars, especially for identifying multiple targets over wide terrain.

Field Scenario Example

A hunter in early spring, shifting between moving through thickets and glassing across open pastures, might find a compact monocular like the Pulsar Axion XQ30 Pro Compact best for balancing scanning speed and moderate observation needs. Huntress Freya Askjaer explains:

“For me, the choice between a thermal monocular and binoculars always comes down to the type of hunt and the terrain. When I’m stalking through dense woodland or moving between stands, I prefer the lightweight flexibility of a monocular — it’s quick to grab and easy to pack. But when I’m in open fields or sitting for hours in a high seat, binoculars give me the comfort and depth I need to scan wide areas for roe deer or foxes without straining my eyes.”

Conclusion & Next Steps

Thermal monoculars and binoculars each serve a clear purpose in the modern hunter’s toolkit. Monoculars typically deliver lighter, more agile scanning capabilities, making them well-suited for stalk hunters covering large, varied terrain. Binoculars, by contrast, offer more natural, fatigue-reducing observation for stand hunters who rely on long hours of patient glassing.

Ultimately, the right choice depends on how you hunt, what terrain you cover, and how long you need to stay on target. Think about whether fast scanning or immersive comfort matters more for your personal hunting style.
