Guide TU650L 3.0 Thermal Riflescope with LRF

The Guide TU650L 3.0, also known as the TU650 LRF 3.0, is the 50 mm model of Guide's TU LRF 3.0 series: a 640 × 512, 12 μm sensor rated ≤18 mK behind a 50 mm F1.0 lens, a laser rangefinder rated to 1,500 m (1,630 yd) with on-screen holdover, and an 815 g body. The Alpen Apex 640 50mm with LRF shares the sensor format and the 2,600 m detection rating, weighs less at 632 g and is rated for up to 15 hours on both batteries; the TU650L answers with ≤18 mK against ≤20 mK, a 1920 × 1080 display against 1440 × 1080 and four times the storage, and it costs less. The Athlon Cronus ATS Pro 50L-640 is rated to run longer, at 10 hours or more, but weighs 42.3 oz against the TU650L's 28.75 oz and uses a 640 × 480 sensor.

Key Features

• 50 mm reach on a 640 × 512 sensor. Each pixel covers 0.24 mrad (12 μm ÷ 50 mm), about 2.4 cm at 100 m. The TU650L starts at 3.9x and zooms to 31.2x, its field is 8.2° × 5.0° (14 × 9 m at 100 m), and detection is rated at 2,600 m.
• Hyper-light and super-resolution. The scope runs Hyper-light image processing and a super-resolution algorithm based on an AI learning model.
• Shutterless 3.0. The shutterless design calibrates without the clicking sound or the image freezing, so the view stays live while you follow an animal. A shutter module is retained for image quality at startup and through large temperature changes.
• Rangefinder with on-screen holdover. Single or continuous ranging to 1,500 m, with the angle beside the distance. Ballistic profiles A to J are built in the TargetIR Ballistics app from data such as bullet type, distance, temperature and wind, then sent to the scope over Wi-Fi. With the calculator on, a press of the B button ranges and shows the holdover in MOA or MIL.
• Ten saved setups. Configurations A to J each store a reticle (ten styles, five colors, five brightness levels), a center-point style and zeros at 100, 200 and three custom distances, so one scope can move between rifles or loads. BTC re-centers the reticle after zeroing.
• Hot track, outlines and picture-in-picture. Hot track follows the warmest point on the screen, image outlining draws the contours of warm targets, and picture-in-picture magnifies the center of the view twice.
• Recoil-triggered recording. When on, each shot saves a clip from 5 seconds before the recoil to 10 seconds after, plus 5 photos, with sound, to 128 GB, at one of five sensitivity levels.
• Two batteries and smart sleep. A built-in 18500 works with an external 18650, and Guide rates the working time at more than 6 hours at 25 °C (77 °F). The USB-C port powers and charges the scope. With nothing connected, smart sleep puts it on standby after 3 minutes at 50° or more of tilt with no button pressed; the power button wakes it.
• Lighter body, sealed for weather. The TU LRF 3.0 is over 200 g lighter than its predecessor with the same configuration. It is sealed to IP68, rated for 6,000 J of shock and .300 Win Mag recoil, and specified for -4°F to 122°F.

Ideal For

• Open-country predator hunters calling across pasture and cut fields. At 0.24 mrad per pixel against a 35 mm lens's 0.34, the 50 mm lens puts about 1.4 times as many pixels across an animal at the same distance.
• Hog hunters on large ag ground who range the shot before the group moves.
• TU650L or TU635L. The TU635L shares the sensor, rangefinder and display behind a 35 mm lens: a wider 11.8° × 7.1° field from 2.8x, Guide's 1,800 m detection rating against 2,600 m, and 785 g against 815 g, and it costs less. Take the TU650L for open ground and distance, the TU635L for cover and closer work.
• TU650L or TU650LS. The TU650LS, built on Guide's newer ApexVision S1 architecture, rates its sensor at ≤15 mK and puts the rangefinder in the objective of a 50 mm F0.9 lens, with a 1.03-inch 2560 × 2560 display and 14 hours, at 935 g. Its rangefinder is rated to 1,200 m against the TU650L's 1,500 m, and it costs more.
• TU650L, TU650P or TU650M. The TU650P keeps a 1,500 m rangefinder but moves it into the objective of a 50 mm F0.9 lens, with the 2560 × 2560 display and 14 hours, at 923 g. The TU650M adds a digital night vision channel, at 1,013 g. Both cost more.
• Against the Alpen and the Athlon. The Alpen Apex's field is taller, 8.7° × 6.89° against 8.2° × 5.0°. The Athlon's 0.49-inch display is 1440 × 1080 against 1920 × 1080, and both scopes store 128 GB.

Accessories & Compatibility

• Mounting. A standard 30 mm tube, with Guide's quick-release mount in the box.
• App and remote. Wi-Fi (2.4 or 5 GHz) links to the TargetIR app for live view, control and firmware updates. Bluetooth pairs Guide's optional remote control, and a spare 18650 is optional too.
