GUIDE TU435LS LRF Thermal Scope 400x300

The GUIDE TU435LS is GUIDE's latest 400×300 thermal riflescope, built around the new APEX VISION infrared imaging system — a significant step forward in AI-powered thermal performance that delivers sharper target detail, cleaner heat separation, and more reliable imagery across a wider range of field conditions than previous generation scopes. At its core sits a highly sensitive 400×300 thermal sensor with NETD <15mK, paired with a 35mm F1.0 lens delivering detection out to 1,800 metres. Add a 1,200m in-lens laser rangefinder with ballistic calculator, 14-hour dual battery runtime, a conventional zoom ring that handles identically to a traditional daytime scope, and an included quick-release (QD) scope mount for fast, repeatable mounting — and the TU435LS delivers serious thermal performance at a more accessible price point than its 640-sensor stablemates.

Features & Specifications
