Pixfra Pegasus 2 LRF vs NocPix Ace: An Honest Thermal Riflescope Comparison

Pixfra Australia Field Journal · Buying Comparison

Two names that keep turning up on Australian thermal shortlists are the Pixfra Pegasus 2 LRF and the NocPix Ace. Both are proper thermal riflescopes from companies that fabricate their own detectors, both drop into conventional 30mm rings, and both come with the sort of spec sheet that makes a fox in a paddock a very bad career choice. So this is not a story about a real optic versus a pretender. It is a story about two capable rivals and where the money actually goes.

Short answer: if you want the lightest total spend with a laser rangefinder built into every configuration and repairs handled here in Australia, the Pegasus 2 LRF makes the stronger case. The NocPix Ace is genuinely good glass with a superb display and in-house sensor pedigree, and it matches the Pegasus on NETD at 640. But rangefinding costs extra on the Ace, and it typically costs more overall.

Who makes the Pegasus 2 LRF and the NocPix Ace?

This is the part where a lot of comparison articles reach for a manufacturer-versus-rebadger argument. We are not going to, because it would be untrue. Both of these brands genuinely build their own sensors.

Pixfra is a genuine thermal sensor manufacturer and part of the Dahua group, one of the world’s largest imaging manufacturers. The Pegasus 2 LRF runs a Pixfra-made 12µm detector, the PIPS 3.0 image engine, and — the feature we will keep coming back to — a 1,000 m laser rangefinder on every single configuration.

NocPix is the outdoor brand of Yantai IRay, the InfiRay group, and it is one of the few genuinely vertically integrated makers in the category: IRay designs and fabricates its own 12µm VOx microbolometers. That is real pedigree, and it shows in the Ace — a mature Reality+/Vision+ processing pipeline with ballistics, dual-battery power, standard 30mm-tube Ace models, and a lovely 1.03″ AMOLED 2560×2560 display. Anyone telling you the Ace is a cut-price import with someone else’s sensor inside it hasn’t done their homework.

What does NETD mean, and why does it matter?

NETD (noise-equivalent temperature difference), measured in millikelvin, tells you the smallest temperature difference a sensor can resolve. Lower is better: a lower NETD means the optic can pick a warm animal out of a background that is only slightly cooler — the difference between “there’s clearly a pig” and “is that a pig or a warm rock?” on a heavy-dew morning. We go deeper in what NETD means for thermal.

Here the two are closer than close. At 640, the Pegasus 2 LRF and the NocPix Ace H50/H50R both sit at ≤15 mK — call that a genuine draw. The only gap is at the entry class: the 384 Ace L35 is rated ≤18 mK, while the Pegasus 384 (P335-LRF) holds ≤15 mK. So Pixfra has a slight sensitivity edge at the bottom of the range, and the field is level once you reach 640.

Does the NocPix Ace have a laser rangefinder?

Some of them do, and this is the single biggest practical difference between the two ranges. On the Pegasus 2 LRF, a 1,000 m laser rangefinder is standard on every configuration, right down to the $2,890 entry model, and it feeds the onboard ballistic calculation. On the NocPix Ace, a built-in rangefinder only appears from the Ace H50R (640/50) upward, at around 1,200 m. The 384 Ace L35 and the 640 SLIM H35 have no built-in LRF at all.

Why does that matter after dark? Because thermal flattens the world. Without a range figure you are guessing hold-over on an animal you cannot see clearly against terrain you cannot judge, and at night your eyes give you almost nothing to correct with. A rangefinder that talks to the ballistic solver turns “about 180, maybe 200” into a number. We put ranging near the top of any buying decision — see the cheapest thermal scope with a rangefinder and detection, recognition and identification range for the why.

How far can each detect game?

Detection range is set overwhelmingly by the objective lens, not by badge or brand, so at equal lens the two are effectively a dead heat. At 35mm both detect out to roughly 1,800 m; at 50mm both reach roughly 2,600 m. Those are detection figures — spotting a heat signature — not recognition or identification distances, which are much shorter and where sensor resolution starts to matter. If you want to understand the difference between simply seeing a blob and confidently identifying what it is, this guide lays it out, and 384 vs 640 covers why resolution changes the picture up close.

How do the two compare on price?

This is where the honest gap opens up. Matched class for class, the Pegasus 2 LRF costs less every time — and at the entry class it costs less and includes a rangefinder the Ace L35 simply doesn’t have.

Pixfra prices are exact AU retail incl GST. NocPix prices are indicative Australian retail at the time of writing; they vary between retailers and over time — confirm current detail with the relevant seller. The SLIM H35 is a separate 2-in-1 QD-mount line rather than an Ace model, listed here only as the nearest 640/35mm equivalent.

We should be careful about what that gap means. It is not that the Ace is overpriced — it is a premium, in-house-sensor optic and it is priced like one, with a genuinely lovely display. Pixfra’s position is different: don’t pay too much for thermal. The Pegasus is well-priced, not cheap — a real sensor-maker’s optic that leaves the rangefinder in the box at every tier and asks a fair price rather than a premium tax. You are not buying the cheapest thing on the shelf; you are buying the one that doesn’t ask you to pay extra for the fundamentals.

How are the two built?

Both are properly made. The Pegasus 2 LRF uses a conventional 30mm main tube that drops into any quality 30mm rings — no proprietary mount to source, so you fit it like any traditional scope and you are not locked into one bracket. Power is a dual 18650 arrangement (a rechargeable internal cell plus a replaceable external one) good for around 9–10 hours, charged over USB-C. It is rated IP67 and to 1,000 g recoil, carries 64 GB of onboard storage, WiFi, recoil-activated recording, picture-in-picture and six colour palettes.

The Ace answers with real strengths of its own. The standard Ace models also use a 30mm tube, so mounting is just as painless. Its dual-battery system pairs a 4000 mAh internal cell with a hot-swap 18650, so you can keep running by swapping the external cell without powering down — a genuinely nice touch on a long night. The headline is that 1.03″ AMOLED 2560×2560 display, which is a step up in sharpness and contrast, and the Reality+/Vision+ pipeline brings mature ballistics, app connectivity and onboard recording. Some Ace models also offer optical ocular zoom, which preserves resolution as you magnify rather than simply enlarging pixels. If display quality and hot-swap power are what keep you out in the paddock, the Ace earns its keep.

Is the Pegasus 2 LRF warranted in Australia?

Yes — and this is a difference worth as much as any spec. The Pegasus 2 LRF carries a Pixfra manufacturer warranty of 3 years on internal components and housing, with 1 year on the rechargeable battery. More importantly for peace of mind, it is distributed and serviced in Australia by C.R. Kennedy, a name trusted in Australian optics since 1934. If something needs attention, the unit is assessed and repaired here in Australia — never shipped overseas. You are dealing with a local service backbone, not a freight-forwarding exercise.

NocPix makes strong optics and, in some markets, backs them with generous cover (up to five years in places). But Australian support for the Ace is importer-dependent, and that can mean longer turnarounds and less certainty about where your scope actually goes for repair. When you are relying on a thermal for real work, “who fixes it, and where” is not a footnote.

Which thermal riflescope should you buy in 2026?

Let’s be fair to the Ace, because it earns it. NocPix is a serious, capable thermal maker with its own sensor, a premium AMOLED display, optical ocular zoom on some models, hot-swap power and a mature software ecosystem. If your priority is the sharpest possible image and you are happy to pay for it — and to add a rangefinder separately, or step up to the H50R — the Ace is a genuinely excellent choice and we would never talk you out of it.

But for most Australian hunters weighing the whole package, the Pegasus 2 LRF is the more sensible buy. Both makers build their own sensors, so this is not a quality-of-manufacturer argument — both run fine NETD, level at 640. The honest decision comes down to three things: price (Pixfra is materially cheaper at every class), ranging (a 1,000 m LRF on the $2,890 entry model, where the Ace L35 has none), and local support (C.R. Kennedy here in Australia versus importer-dependent cover). That is the definition of well-priced, not cheap: a genuine sensor-maker’s optic that includes the fundamentals and asks a fair price.
