The ThermTec Ares-LRF 335L is a thermal rifle scope built on a standard 30 mm tube body, designed for night-time target detection, pest control, and game management. Combining an uncooled 384 × 288 VOx microbolometer with a 35 mm F/1.0 objective lens, it delivers a 3.2× optical base magnification and up to 5.0× continuous digital zoom onto a 1024 × 768 AMOLED micro-display. An integrated laser rangefinder measures distances up to 1,000 m with ±1 m accuracy at 100 m, providing precise distance data for medium-range field engagements.

Key Features

• Integrated Laser Rangefinder: Accurately measures target distances up to 1,000 m to assist with rapid ballistic calculation.
• Thermal Detection Range: 12 µm sensor with NETD ≤ 25 mK (≤ 18 mK on Ares 2.0 models) provides human detection signatures at ranges up to 1,800 m.
• Dual-Battery System: Utilises an internal rechargeable battery combined with a replaceable external 18650 or 18500 lithium-ion cell, delivering 12 to 18 hours of continuous runtime.
• Heavy Recoil Rating: Rated to withstand mechanical shock up to 850 Gs, ensuring compatibility with heavy centerfire calibres including .300 Win Mag and .375 H&H.
• Shooting Enhancements: Features Recoil Activated Video (RAV), automated first-shot zeroing, picture-in-picture (PIP), 5 zeroing profiles, 6 colour palettes, and 7 reticle configurations.
• Mounting Compatibility: Standard 30 mm tube chassis mounts directly to standard rifle rings and tactical platforms.

Who is the ThermTec Ares-LRF 335L Thermal Tube Scope for?

• Medium-range night pest controllers targeting foxes and wild dogs — relies on the 35 mm F/1.0 objective lens, 384 × 288 pixel resolution, and integrated 1,000 m rangefinder on this thermal scope to achieve positive quarry identification and precise ranging within 150 m to 250 m engagement windows.
• Feral pig eradication shooters operating in low-light conditions — benefits from the 850 Gs recoil rating on this thermal scope, maintaining zero and structural integrity when mounted via its 900 g chassis onto heavy centerfire calibres up to .300 Win Mag and .375 H&H during high-volume culling.

Less suitable for: Long-range open-plains pest control requiring positive quarry identification beyond 300+ m, where larger 50 mm or 60 mm 640 × 512 thermal rifle scopes are better suited; or ultra-lightweight walkabout stalking where compact thermal monoculars or mini thermal scopes are preferred over a 900 g tube optic.
