Guide TD435LS Thermal Monocular with LRF

The Guide TD435LS Thermal Monocular has been upgraded with the latest ApexVision technology from Guide Sensmart. Equipped with a highly sensitive 400×300 @12μm thermal detector with an impressive NETD of <15mK, it provides clear thermal imagery and enhanced target detection in challenging weather and low-visibility conditions.

Featuring an integrated 1200m laser rangefinder, the TD435LS allows users to accurately measure distances while maintaining a lightweight and ergonomic design. The intuitive focusing roller enables smooth one-handed operation, while the symmetrical housing ensures comfortable use with either hand.

Combining advanced thermal performance, long battery life, laser rangefinding capability, and a compact form factor, the Guide TD435LS LRF is an ideal solution for wildlife observation, pest control, search and rescue, security applications, and general outdoor exploration.
