The ThermTec Ibex 335L Thermal Tube Scope (part number OPTT-IBEX335L) is a thermal riflescope designed for medium- to long-range night shooting and pest management. Built around a standard 30 mm tube format, the optic mounts directly to sporting rifles using standard scope rings without requiring proprietary rail adaptors. It combines a 384 × 288 uncooled VOx sensor, an integrated 1,000 m laser rangefinder (LRF), an onboard ballistic solver, and an ergonomic central top focus turret. Operating across temperatures from -20 °C to +50 °C with an IP67 water and dust ingress rating, the scope delivers up to 6 hours of continuous runtime, rechargeable via a standard 5V USB-C connection.

Key Features

• Thermal Core & Optics: Uses a 384 × 288 VOx microbolometer with a 12 μm pixel pitch and sub-18 mK NETD thermal sensitivity paired with a 35 mm objective lens and 50 Hz refresh rate.
• Integrated Rangefinding and Ballistics: Features a built-in laser rangefinder accurate up to 1,000 metres combined with an internal ballistic calculator for real-time holdover corrections.
• Central Turret Focus: Top-mounted central focus turret allows ambidextrous image adjustment while maintaining a shooting grip, replacing traditional front objective focus rings.
• Display & Detection: High-resolution 1600 × 1200 AMOLED display offers a 7.5° × 5.7° field of view and human/game detection ranges up to 1,800 metres.
• Standard 30 mm Housing: Traditional aluminium tube profile measures 344 mm × 86 mm × 70 mm and weighs 770 g (excluding battery).

Who is the Thermtec Ibex 335l for?

• Medium- to long-range pest eradication hunters — pairs a 35 mm objective lens with a 384 × 288 sensor and sub-18 mK NETD sensitivity to detect foxes, feral pigs, and wild dogs at ranges up to 1,800 metres while adding 770 g to standard 30 mm rifle ring setups.
• Night predator management shooters — utilizes an integrated 1,000 m laser rangefinder combined with an internal ballistic solver to calculate real-time holdover on distant targets via this thermal tube scope.

Less suitable for: Hunters operating in tight, dense bush under 50 metres who require a wider field of view (better served by a 19 mm or 25 mm short-range thermal optic), or shooters requiring ultra-high target identification beyond 300 to 400 metres (better served by a higher-resolution 640 × 512 thermal platform).
