GUIDE TB650 PRO LRF 2.0 50mm 640×512 Thermal Clip-On

The GUIDE TB650 PRO LRF 2.0 Thermal Clip-On combines a high-resolution 640×512 thermal sensor, 50mm F/0.9 germanium lens, integrated 1,630-yard in-lens laser rangefinder, G-Zero shutterless imaging, and a full-HD AMOLED display in a premium long-range thermal clip-on.

Mount it in front of a compatible daytime riflescope to add thermal capability while continuing to use the reticle, eye relief, magnification range, and rifle setup you already trust. Designed for use with daytime optics up to 15× magnification, the TB650 PRO LRF 2.0 is built for hog, coyote, and predator hunters who need better detail and ranging capability across large fields and open terrain.

The TB650 PRO LRF 2.0 also includes photo and video recording, recoil-activated recording, audio, 64GB of internal storage, Wi-Fi, Bluetooth, AI target tracking, handheld viewing mode, and USB-C external power support.

Add Thermal to Your Existing Daytime Scope

The GUIDE TB650 PRO LRF 2.0 mounts in front of a compatible daytime riflescope, allowing you to continue using your familiar reticle, magnification controls, eye relief, and shooting position.

This eliminates the need to replace your daytime optic with a dedicated thermal riflescope or learn an entirely different reticle and control system. Once properly mounted, aligned, and calibrated, the rifle can transition between daytime and thermal operation without removing the primary optic.

GUIDE rates the TB650 PRO LRF 2.0 for daytime optics up to 15× magnification. Its 640×512 sensor and 1920×1080 AMOLED display provide more image information for the daytime scope to magnify, helping retain useful target detail at higher magnification.

The system provides fine 0.48-inch adjustments at 60 yards and can save five separate zero profiles for different rifles, optics, or mounting configurations.

Mounting system sold separately. The correct adapter ring or Picatinny QD mount must be selected based on your riflescope and rifle setup.

640×512 Sensor With 18 mK Sensitivity

At the heart of the TB650 PRO LRF 2.0 is an uncooled 640×512 VOx thermal sensor with a 12μm pixel pitch, 18 mK thermal sensitivity, and 50 Hz refresh rate.

The high-resolution sensor provides the detail needed to separate animals from surrounding terrain and maintain a usable image as daytime-scope magnification is increased.

Its 18 mK NETD rating allows the sensor to recognize small temperature differences when humidity, fog, rain, vegetation, or changing temperatures reduce environmental contrast.

The 50 Hz refresh rate keeps movement smooth while scanning, tracking running hogs, or following coyotes moving across open fields.

50mm F/0.9 Lens for Long-Range Hunting

The 50mm F/0.9 germanium objective lens is designed for hunters who prioritize distance and target detail.

The TB650 PRO LRF 2.0 provides a listed thermal detection range of approximately 2,800 yards under ideal conditions. Its 8.8° × 6.6° field of view covers approximately 15 × 11 meters at 100 meters, making it well suited for large fields, agricultural ground, wide pastures, and long shooting lanes.

Detection range represents the ability to recognize the presence of a heat source and should not be confused with positive identification or practical shooting distance.

Integrated 1,630-Yard In-Lens Laser Rangefinder

The TB650 PRO LRF 2.0 integrates its laser rangefinder directly into the objective lens instead of placing a separate LRF module on the side of the housing.

This in-lens design keeps the unit more streamlined and reduces the parallax error that can occur when the thermal image and rangefinder are positioned on different optical axes.

GUIDE lists a maximum ranging distance of approximately 1,630 yards, giving hunters accurate distance information without reaching for a separate handheld rangefinder.

Single and continuous ranging modes are available. The unit can also display absolute or horizontal distance, which is useful when ranging from an elevated position.

G-Zero Shutterless Imaging

GUIDE’s G-Zero shutterless technology is designed to eliminate the routine image freezing and audible clicking associated with traditional thermal calibration.

During normal operation, the image remains smooth and uninterrupted while you scan, track, and aim. This reduces the risk of losing sight of a moving animal during a calibration cycle.

An internal shutter is retained for startup and significant temperature changes to help maintain image quality, but routine operation remains quiet and free from disruptive image freezes.

Hyper-Light Image Enhancement

The TB650 PRO LRF 2.0 uses GUIDE’s Hyper-Light image-processing algorithm to improve:

• Image contrast
• Environmental detail
• Target separation
• Edge definition
• Noise reduction
• Fine thermal detail

Natural, Enhanced, and Highlight scene modes allow the image to be adjusted for different weather, terrain, and thermal conditions.

Full-HD AMOLED Display

The TB650 PRO LRF 2.0 pairs its thermal sensor with a 0.39-inch 1920×1080 AMOLED display.

The full-HD display provides the resolution needed for use behind a magnified daytime optic while delivering strong contrast, deep blacks, and smooth image reproduction.

Seven thermal color palettes are available:

• White Hot
• Black Hot
• Red Hot
• Green Hot
• Iron Red
• Blue Hot
• Sepia

Warm and cool display-tone options are also available. The cool setting emphasizes detail and target separation, while the warm setting produces a softer image that can reduce eye fatigue during extended use.

AI Target Tracking

The TB650 PRO LRF 2.0 includes AI-assisted target tracking designed to help locate newly appearing animals within the thermal image.

When enabled, the system can mark newly detected animals and track multiple heat signatures within the scene. It can also provide a separate warning indication when a person is detected.

This can be helpful when scanning fields containing multiple hogs, tracking animals through vegetation, or monitoring a large area where new heat signatures can appear quickly.

Recoil-Activated Recording

With 64GB of internal storage, the TB650 PRO LRF 2.0 can capture photos and videos with audio without requiring a separate memory card.

Its recoil-activated Smart Recording feature automatically saves:

• Five seconds of video before the shot
• Ten seconds of video after the shot
• Five photos following the shot

Recorded footage can be played back through the unit or viewed through the GUIDE TargetIR mobile app. An optional virtual-reticle overlay can also be added to recorded footage to better represent what the hunter saw through the daytime optic.

Wi-Fi, Bluetooth and TargetIR App

Dual-band 2.4 GHz and 5 GHz Wi-Fi allows the TB650 PRO LRF 2.0 to connect with the GUIDE TargetIR app.

Through the app, users can:

• View the live thermal image
• Capture photos and videos
• Access recorded footage
• Adjust device settings
• Install firmware updates

Bluetooth connectivity supports an optional remote control, allowing commonly used functions to be operated without reaching forward to the clip-on.

Handheld Thermal Monocular Mode

The TB650 PRO LRF 2.0 can also operate as a handheld thermal monocular.

Handheld mode removes the clip-on zeroing scale and allows the thermal image to be digitally enlarged for scanning. This gives hunters the option to use the unit for observation before mounting it in front of the daytime riflescope.

Replaceable 18650 Battery System

The unit operates on a single replaceable 18650 rechargeable battery and provides up to approximately five hours of runtime, depending on temperature, recording, wireless connections, settings, and use.

Two batteries and a charger are included, allowing one battery to be used while the second remains charged and ready.

The USB-C port supports external power but does not charge the installed battery. Batteries must be charged in the included external charging dock.

Built for Recoil and Harsh Weather

The TB650 PRO LRF 2.0 is rated to withstand recoil energy up to 6,000 joules while maintaining a stable image with minimal point-of-impact shift.

Its IP68 environmental rating provides protection against dust and water, while the listed operating temperature range of -4°F to 122°F supports use across demanding hunting conditions.

The unit measures approximately 5.67 × 3.39 × 3.11 inches and weighs 17.28 ounces without a mounting adapter.
