Guide TU635LS 3.0 Thermal Riflescope with In-Lens LRF

The Guide TU635LS is the 35 mm, 640-class model of Guide's TU Pro 3.0 series: a 640 × 512, 12 µm sensor rated at 15 mK behind a 35 mm F0.9 lens with the laser rangefinder inside the objective, and a 1.03-inch 2560 × 2560 AMOLED. Next to the TU635L, which pairs the same sensor format with a 35 mm lens, it moves to 15 mK from 18 mK, F0.9 from F1.0, the 2560 × 2560 display from 1920 × 1080, 60 mm of eye relief from 48 mm, and a 14-hour battery rating from more than 6 hours. The TU635L ranges farther (1,500 m against 1,200 m) and is lighter (785 g against 875 g).

Key Features

• ApexVision S1 imaging. Guide pairs its ApexCore S1 detector with the Nexus 1.0 platform and the Hyper-Light 2.0 algorithm, which Guide says improves clarity, reduces noise, optimizes contrast and resolves finer detail. The sensor runs at 50 Hz with a 15 mK rating.
• Rangefinder inside the objective. The laser rangefinder sits on the lens axis instead of in a separate window. Guide says this reduces parallax error in ranging and keeps the scope compact. It ranges to 1,200 m (1,300 yd).
• Large square display. The 1.03-inch 2560 × 2560 AMOLED has 60 mm of eye relief and a -5 to +5 diopter. Magnification starts at 2.6x and reaches 20.8x with 8x digital zoom, across a 12.5° × 10.0° field.
• Shutterless 3.0. Calibration runs without the shutter click or the image freeze, so the view stays live while you follow an animal. Guide keeps a shutter module for image quality at startup and through large temperature changes.
• Three batteries, 14 hours. Two built-in 18650 cells work with a third, replaceable 18650 for a rated 14 hours, and Guide says the replaceable cell supports hot swapping. USB-C supplies external power and charging.
• Recoil-activated recording. Each shot saves a 15-second clip and 5 photos for instant playback. Photos and video record with audio to 128 GB of internal storage.
• Built for recoil and weather. Rated for 6,000 J shock, sealed to IP68 and specified for -4°F to 122°F (-20°C to 50°C).
• Central focus and zoom. A centrally placed focus wheel and zoom lever handle focus and magnification.
• App and remote. Dual-band Wi-Fi (2.4 and 5 GHz) links the TargetIR app for live view, photos, video, settings and firmware updates. Bluetooth pairs Guide's optional remote control.
• Reticles, zeros and ballistics. Guide's TU 3.0 series manual describes ten saved configurations (A to J) with zeros at up to five distances, and a ballistic calculator that uses each range reading and the measured angle to give a correction in MOA or MIL. Seven thermal palettes are included.

Ideal For

• Hunters in timber, brush and broken country, where a 12.5° × 10.0° field and a 2.6x starting magnification make it easier to find and follow an animal at closer range.
• Night hog hunters who want ranging, recoil-triggered recording and a 14-hour battery rating in one scope.
• Hunters coming from a 0.49-inch 1080p scope, such as the TU635L, who want the 1.03-inch 2560 × 2560 display and 60 mm of eye relief.

TU635LS, TU650LS or TU435LS. The TU650LS puts the same sensor behind a 50 mm lens, for a 3.7x start, an 8.8° × 7.0° field, Guide's 2,600 m detection rating against 1,800 m, and 256 GB of storage. The TU435LS shares this scope's 35 mm lens, display, rangefinder and battery system with a 400 × 300 sensor, so it starts at 4.2x across a narrower 7.9° × 5.9° field.

Accessories & Compatibility

The TU635LS has a standard 30 mm tube and comes with Guide's quick-release scope mount. Guide offers a Bluetooth remote control and spare 18650 batteries as optional accessories.
