Guide TU Pro 3.0 Series LRF Thermal Imaging Rifle Scopes
The Guide TU Pro 3.0 Series combines premium thermal imaging with a laser rangefinder integrated directly into the objective-lens assembly. This compact LRF-in-lens design keeps the rangefinder close to the optical axis to reduce parallax error and support more accurate distance measurement without adding a bulky external module.
Available as the TU435LS, TU635LS, and TU650LS, the series offers a choice of 400 × 300 or 640 × 512 thermal resolution, 35 mm or 50 mm F0.9 optics, a 1.03-inch 2560 × 2560 AMOLED display, and laser ranging to 1,200 metres. All three models use Guide's ApexVision S1 architecture and Hyper-Light 2.0 processing for clear, detailed thermal images in demanding field conditions.
Key Features
- Integrated 1,200 m laser rangefinder: The rangefinder is built into the lens assembly for a clean scope profile and more precise alignment with the viewing axis.
- ApexVision S1 architecture: Combines Guide's ApexCore S1 detector, Nexus 1.0 platform, and Hyper-Light 2.0 algorithm to improve clarity, contrast, fine detail, and motion rendering.
- High thermal sensitivity: A 15 mK NETD specification helps distinguish small temperature differences in low-contrast environments.
- Large QHD AMOLED display: All three models use a 1.03-inch 2560 × 2560 AMOLED display with 60 mm eye relief for a detailed, comfortable sight picture.
- Shutterless 3.0 viewing: Minimizes calibration-related clicking and image interruption during observation and aiming.
- Long-life dual-battery system: Built-in and replaceable 18650 batteries provide up to 14 hours of operation, with hot swapping for extended field use.
- Recoil-activated recording: Automatically captures a 15-second video and five photos when recoil is detected, with instant playback.
- Dual-band Wi-Fi and Bluetooth: Supports 2.4 GHz and 5 GHz Wi-Fi, mobile-app connectivity, and compatible remote-control options.
- Standard 30 mm tube: The traditional scope format is compatible with suitable 30 mm mounting systems.
- Field-ready construction: IP68 protection and recoil resistance up to 6,000 J support dependable use in rain, snow, dust, and harsh outdoor environments.

Which Guide TU Pro 3.0 Scope Should You Choose?
TU435LS — High Magnification and Strong Value: The 400 × 300 sensor and 35 mm F0.9 lens deliver a 4.2× base magnification in the most accessible Pro model. It is well suited to users who prioritize magnification, integrated ranging, and the premium 2560 × 2560 display.
TU635LS — Wide-View 640 Resolution: Its 640 × 512 sensor, 35 mm F0.9 lens, and wider 12.5° × 10.0° field of view make it the most versatile model for scanning, locating moving animals, and working across mixed terrain.
TU650LS — Long-Range 640 Performance: The 50 mm F0.9 lens provides greater base magnification and the longest detection capability in the series, making the TU650LS the preferred choice for open terrain and more demanding long-range observation.
Integrated Ranging and Ballistic Support
Accurate distance information is especially valuable when target size, terrain, and environmental conditions make visual range estimation difficult. The TU Pro 3.0's integrated LRF measures distance without changing the scope's streamlined profile. When connected to the compatible Guide TargetIR Ballistics app, supported functions can assist with ballistic calculations and field setup.
Designed for Canadian Hunting and Professional Use
The TU Pro 3.0 Series is built for predator and varmint hunting, farm protection, wildlife management, and qualified professional applications. Its high-sensitivity thermal core, integrated rangefinder, long battery life, and weather-resistant construction are well suited to extended use in darkness, cold temperatures, wet weather, and difficult terrain.
