It’s the question that trips up nearly every first-time thermal buyer: do you want a monocular or a riflescope? They look related, use the same core technology, and cost broadly similar money — but they do opposite jobs, and buying the wrong one is an expensive lesson. Here’s the honest breakdown, and the setup most experienced hunters actually end up running.
Quick verdict
A thermal monocular is a handheld scanner for finding and identifying animals; a thermal riflescope mounts on your rifle for taking the shot. The rule is simple: scan with a monocular, shoot with a scope. If you can only buy one for hunting, buy the scope — but most serious hunters end up running both.
What’s the actual difference?
A monocular is a detection device. It has no reticle and doesn’t mount to your rifle — you hold it up, glass a paddock in under a minute, and find warm animals bedded in cover. A riflescope is a shooting device: it has a zeroable reticle, holds ballistic profiles, and is built to take repeated centrefire recoil. They aren’t interchangeable, and each does its own job far better than the other’s.
| Thermal monocular | Thermal riflescope | |
|---|---|---|
| Main job | Scanning & detection | Aiming & shooting |
| Reticle / zero | No | Yes |
| Mounts to rifle | No (handheld) | Yes |
| Recoil-rated | Not needed | Yes (IP67, 1000 g) |
| Best for | Finding game, navigating, recovery | Taking the shot |
| Pixfra example | Mile 2 (from $890), Arc LRF (from $1,990) | Cetus (from $1,190), Pegasus 2 LRF (from $2,890) |
Why scanning with a scope is a bad idea
You can sweep a paddock with a rifle-mounted scope — but it’s slow, tiring and genuinely unsafe, because you’re pointing a loaded firearm at everything you want to look at. A monocular lets you glass freely with the rifle slung, and only shoulder up once you’ve found and identified your target. That single habit is the biggest reason experienced shooters carry both.
Which should you buy first?
For hunting, the riflescope earns its place first — it’s the tool that actually lets you take the shot. A capable, well-priced starting scope like the Cetus C225 ($1,190) gets you shooting in thermal. Add a scanning monocular when you’re tired of sweeping the paddock with a rifle-mounted optic — which, if you hunt regularly, won’t take long. If your use is pure observation — pest spotting, checking stock at night, recovery — a monocular alone is the right buy, and you may never need a scope.
Can you use a monocular as a scope?
No. A monocular has no reticle, isn’t zeroed to your rifle, and isn’t built for recoil. It’s a detection device — brilliant for finding animals, wrong for aiming a firearm. Some monoculars can be run as a clip-on ahead of a day scope with the right adaptor, but a handheld held up to a day scope is neither accurate nor safe as an aiming solution.

The both-worlds setup most hunters land on
Most experienced hunters run two tools: a monocular to scan and a scope to shoot. Scan with a lightweight Mile 2 (from $890) or, if you want ranging in hand before you shoulder up, the Arc A425P-LRF ($1,990); shoot with a Cetus or Pegasus 2 LRF. It’s the fastest, safest workflow: find, identify and range with the handheld, then make the shot through the scope. If you’d rather carry one device that does high-detail scanning and recording, the multi-spectral Draco binocular (from $1,790) pairs thermal with 4K day vision and a built-in rangefinder — though it doesn’t replace a rifle-mounted scope for the shot itself.
What about budget — is one cheaper?
Usually the monocular is the cheaper entry: Pixfra monoculars start at $890 (Mile 2), while genuine thermal scopes start at $1,190 (Cetus C225). Adding a laser rangefinder raises either — the ranging Arc starts at $1,990, and the Pegasus 2 with LRF as standard starts at $2,890. Buy the tool that matches the job first; add the second when your hunting tells you it’s time.
This is exactly the gap Pixfra CrossLink closes: your handheld does the finding and ranging, then hands it to the scope. A Draco can send range, holdover and a live picture-in-picture view straight to a Cetus.
Frequently asked questions
Do I need both a thermal monocular and a scope?
Not to start. One good scope will hunt. Add a monocular when you want faster, safer scanning without swinging a rifle around — most hunters get there eventually.
Is a thermal monocular cheaper than a scope?
Usually. Pixfra monoculars start at $890 (Mile 2), while genuine thermal scopes start at $1,190 (Cetus C225). Adding a laser rangefinder raises either.
What’s the best thermal for scanning?
A dedicated monocular. The Pixfra Mile 2 is light and simple for finding animals; the Arc adds a 1,000 m laser rangefinder if you want to range what you spot.
Can one device do both scanning and shooting?
A riflescope can be used to scan in a pinch, but it is tiring and less safe. For a true dual-purpose scan-and-record tool, look at the Draco multi-spectral binocular rather than a scope.
Which should I buy first for hunting?
The riflescope — it is the tool that lets you take the shot. A Cetus C225 ($1,190) gets you started; add a scanning monocular when sweeping with the rifle gets tiring.
The setup that actually works
The setup most serious hunters land on is a handheld spotter to find and a thermal riflescope to shoot. A good place to start is Pixfra Sirius and Pixfra Cetus. Every one is genuine local stock with full Australian warranty, serviced right here through C.R. Kennedy and never sent overseas.
