HIKMICRO THUNDER 4.0 TX70CL Thermal Add-On

The THUNDER 4.0 TX70CL uses a high-resolution 1280 × 1024, 12 µm thermal detector to reveal animals and surrounding terrain by their heat signatures. A NETD below 12 mK helps distinguish subtle temperature differences, while the 70 mm F1.3 lens supports detailed observation across open ground. The quoted detection range reaches 3,500 metres.

Designed as a front-mounted thermal clip-on, the TX70CL works with a compatible daytime riflescope, allowing you to retain your familiar viewing setup. It provides 1× magnification in clip-on mode, with recommended daytime scope magnification of 1–15×. Image calibration and five zeroing profiles provide flexibility when configuring the unit.

A 1920 × 1080 AMOLED display presents the thermal image, supported by HIKMICRO Image Pro 4.0 processing. The HIKMICRO Shutterless Image System (HSIS) and Sync Pro support responsive, uninterrupted viewing. Six colour palettes, adjustable brightness and warm or cool image tones allow you to adapt the display to your preferences and the conditions.

The laser rangefinder is integrated into the lens assembly and measures distances from 10 to 1,200 metres. This provides convenient distance information without adding a separate external rangefinder module to the unit.

On-board video and audio recording let you document activity in the field, while recoil-activated recording captures footage automatically around a shot. Photographs and videos are stored on 64 GB of internal memory, with a local album for reviewing recordings and hotspot connectivity for wireless use.

A rechargeable, replaceable HM-3840DC battery provides at least five hours of operation at 25°C, with the hotspot switched off and the rangefinder on. USB-C supports direct charging and an external power supply, providing additional flexibility during longer outings.

The body and lens cover are made from magnesium alloy, combining manageable weight with a robust construction. IP67 protection, a −30°C to +50°C operating range and a stated maximum recoil resistance of 6,000 J make the TX70CL suitable for demanding field conditions. A soft-closing magnetic lens cap and lever-style power switch add practical convenience.
