The Best ThermTec Thermal Scopes in Australia (2026)

Quick answer: For most Australian hunters in 2026 the best ThermTec thermal scope is the Oryx 650L LRF — a 640×512/12µm sensor with an in-lens ballistic rangefinder and a sharp 2560×2560 OLED — with the Ares 650 2.0 the value pick in the 640 tier, the Vidar 360 2.0 the compact choice, and the IBEX 335L LRF the rangefinder-equipped entry. Choose by objective lens and field of view, not sensor size alone.

ThermTec has become one of the most popular thermal brands in Australia, and for good reason — class-leading battery life, well-judged ergonomics and a riflescope line that spans entry-level all the way to premium. The range is broad, though, so this guide breaks down the best ThermTec thermal scopes in Australia for 2026, explains what the model codes mean, and matches each scope to the kind of hunting it suits.

Hunt The Night carries ThermTec's thermal range as genuine Australian stock with full local warranty support and expert pre-sale advice — and we were closely involved in developing the Oryx line, so we know it inside out.

The ThermTec scope families

• Ares 2.0 / Ares LRF 2.0 — tube-style thermal riflescopes that drop straight into standard rings, with dual field of view, long battery life and (on LRF models) a built-in laser rangefinder.
• Vidar 2.0 / Vidar LRF 2.0 — compact-body riflescopes with a ballistic calculator and dual field of view, for hunters who want a smaller, lighter package.
• Oryx — the premium tube riflescope: an in-lens ballistic rangefinder, a high-resolution OLED and refined controls. Hunt The Night helped develop it.
• IBEX — a compact riflescope built around a 12µm sensor with an integrated ballistic laser rangefinder.

How to read a ThermTec model name

Once you know the code, the whole range makes sense:

• The number reflects the objective lens class in millimetres — 335 ≈ 35mm, 650 ≈ 50mm, 660 ≈ 60mm.
• L = a built-in laser rangefinder (LRF).
• 2.0 marks the current Ares and Vidar generation.

So an Ares LRF 650L 2.0 is a tube-style, current-generation scope with a 50mm-class objective and a built-in rangefinder.

What actually drives performance (and what doesn't)

The lens drives reach, not "sensor size." How far a thermal scope detects is governed mainly by the objective lens working together with the sensor's resolution and pixel pitch — not by the physical size of the sensor. That's why a 50mm-class scope reaches further than a 35mm one running the same sensor, and why pairing a larger lens with a higher-resolution, finer-pitch sensor (a 640×512 at 12µm, for example) keeps detail under magnification where a lower-resolution sensor would fall apart.

NETD is one factor, not the headline. A lower NETD (measured in millikelvin) helps most in low-contrast conditions — rain, fog, humid nights. But the image-processing software inside the scope has just as much influence on what you actually see as a few mK either way. ThermTec quotes figures from ≤15mK to ≤20mK across this range; treat it as one ingredient, not the whole recipe.

The picks

Best overall — ThermTec Oryx 650L LRF

The Oryx 650L is ThermTec's most complete riflescope and our pick for most serious hunters. It runs a 640×512 sensor on a fine 12µm pixel pitch with a ≤15mK NETD and a fast 50mm F0.9 objective, and it finally brings ThermTec into line with the rest of the premium field with a beautiful 2560×2560 1.03" OLED. The ballistic laser rangefinder is built into the lens — ThermTec split the IR sender and receiver to shrink it by around a quarter — and the new top-turret focus and forward zoom control work equally well for left- and right-handers. Add recoil-activated video, WiFi streaming and TASS (return to base magnification when you fire) and it's a genuinely well-thought-out scope. If you shoot beyond ~150m or hunt in humid, foggy or dusty conditions, the 50mm Oryx 650L is the one to have.

Best value in the 640 tier — ThermTec Ares 650 2.0

The Ares 2.0 is the tube scope that made ThermTec a household name with Australian hunters. The 650 2.0 pairs a 640×512 sensor with a dual field-of-view optic, seven reticle choices and the long battery life the brand is known for, all in a body that drops straight into standard rings. It's the sensible starting point for anyone who wants 640-class image quality without stepping up to the flagship.

Best compact — ThermTec Vidar 360 2.0

The Vidar 2.0 line takes the Ares feature set into a smaller, lighter compact body. The 360 2.0 runs a 384×288 sensor with a dual FOV switch, a 1024×768 OLED and a ballistic calculator for precise holds at distance. If you value a trim, fast-handling scope and don't need the largest sensor, the Vidar is the pick.

Best rangefinder entry — ThermTec IBEX 335L LRF

The IBEX 335L builds a 384×288 thermal sensor on a 12µm pixel pitch around an integrated ballistic laser rangefinder accurate to 1,000m — so you get instant distance and a corrected hold in one compact unit. It's the most affordable way into a ThermTec scope with ranging built in.

Beyond riflescopes — clip-ons and monoculars

If you'd rather keep the day scope and zero you already trust, ThermTec's Hunt and Hunt Pro clip-ons mount in front of it; the Hunt 650 Pro runs a 640×512/≤15mK sensor in a 399g magnesium body rated to heavy recoil. For scanning and spotting, the Wild, Cyclops and Cyclone handheld monoculars cover everything from pocket-sized to long-range observation. See our thermal clip-on buying guide and thermal monocular guide for the full picture.

Frequently asked questions

Which ThermTec scope is best for most hunters?

For most Australian hunters the Oryx 650L LRF is the best all-round choice — a 640×512/12µm sensor, ≤15mK NETD, a 50mm objective and a built-in ballistic rangefinder. If you want the same 640 image quality for less, the Ares 650 2.0 is the value pick; for a smaller package, the Vidar 360 2.0.

What does the number in a ThermTec model name mean?

It reflects the objective lens class in millimetres — 335 is roughly a 35mm lens, 650 roughly 50mm and 660 roughly 60mm. A larger number means a larger objective, which generally means more reach. An "L" in the name signals a built-in laser rangefinder.

Does a bigger sensor see further?

No — detection reach is set mainly by the objective lens working with the sensor's resolution and pixel pitch, not by sensor format on its own. A larger lens and a higher-resolution, finer-pitch sensor are what extend usable range and hold detail under magnification.

Is a low NETD the most important spec?

It helps most in low-contrast weather like rain and fog, but the scope's image-processing software matters just as much as a few millikelvin either way. ThermTec quotes ≤15mK to ≤20mK across this range — treat NETD as one factor among several, not the headline number.

Should I choose Ares or Vidar?

They share much of the same technology. Ares is the tube-style scope that fits standard rings and handles like a day scope; Vidar puts a similar feature set into a more compact body. Choose Ares for familiar mounting and handling, Vidar for a smaller, lighter package.

Are thermal scopes legal in Australia?

Thermal scopes are legal to own in Australia, but some states restrict their use for hunting, particularly on public land — always check your state's current regulations. See our guide to thermal and night vision laws in Australia for a state-by-state overview.
