DESCRIPTION
The Guide Sensmart® TA435 Thermal Front Attachment is a compact and versatile clip-on thermal imaging solution that instantly transforms your daytime riflescope into a powerful thermal optic, without the need for re-zeroing. Designed with a sensitive 400×300 VOx uncooled thermal sensor (17 µm pixel pitch) and a fast 35 mm f/1.2 lens, it delivers clear, high-contrast imagery across varied environments. Its 0.39″ OLED display with 1024×768 resolution and 50 Hz refresh rate ensures smooth visuals, while multiple scene modes and colour palettes adapt performance to any conditions. Weighing only 400 g and built to an IP67 standard, the TA435 combines portability, ruggedness, and reliability, making it equally effective as a front-mounted scope attachment or standalone thermal monocular.
Included is a Rusan ARTA435-63 QR One-Piece Adaptor designed to connect the GuideIR to your riflescope.
