Guide TB650S

• 640×512 Thermal Sensor: The 12 μm pixel pitch detector combined with a 15 mK NETD rating delivers fine detail and low-noise thermal imaging, useful for identifying game at extended range.
• Compatible with Daylight Optics up to 15x: Mounted in front of a riflescope, the TB650S turns a standard daylight sight into a thermal setup, supported by 1.22 cm @ 100 m click adjustments for precise zeroing.
• High Recoil Resistance (6000 J): The housing is built to withstand heavy recoil, maintaining stable imaging and consistent point-of-impact even under repeated heavy-caliber shots.
• Lightweight, Palm-Sized Housing: Weighing only 490 g, the compact design keeps the front-end weight balanced when mounted ahead of a daylight scope, supporting comfortable handling in the field.

ABOUT THE TB SERIES

The TB 2.0 Series is Guide's line of thermal clip-on attachments, designed to be mounted in front of an existing daylight riflescope to add thermal imaging capability without replacing the optic. The series is built around Guide's ApexVision S1 system architecture, combining the ApexCore S1 detector, Platform Nexus 1.0, and the AI-powered Hyper-Light image enhancement algorithm to deliver clarity and reduced noise in low-light and long-range conditions.

Models within the TB Series vary by sensor resolution (640×512 or 1280×1024, both at 12 μm pixel pitch) and objective lens configuration, with select models also integrating a laser rangefinder directly into the lens housing for precision ranging without added bulk. All models share a G-Zero shutterless operating design, which removes shutter freezing at startup and reduces shutter calibration noise for silent, uninterrupted operation.

TB Series clip-ons are built for hunting use, offering high recoil resistance (6000 J), a lightweight, palm-sized housing, and a standard replaceable 18650 battery for extended field sessions. Photo and video recording with an optional overlaid virtual reticle allows recorded footage to simulate the actual aiming experience, with local playback available directly on the device.

ABOUT THE MODEL (GUIDE TB650S)

The Guide TB650S is a thermal clip-on attachment built around a 640×512 uncooled VOx infrared detector with a 12 μm pixel pitch and a 15 mK NETD rating, paired with a 50 mm, F0.9 objective lens. This combination provides an 8.8° × 6.6° field of view and a detection range of 2600 m / 2800 yd, with manual focus and a native 1x magnification designed to preserve the daylight scope's own zoom range once mounted.

The device features G-Zero shutterless operation, eliminating the image freeze typically caused by shutter calibration at startup, which helps avoid missed opportunities when a target appears suddenly. Its housing is rated for 6000 J of recoil resistance, supporting stable imaging and consistent point-of-impact even under repeated firing with heavier calibers. Zeroing is handled through 1.22 cm @ 100 m click adjustments, and the unit is compatible with daylight optics up to 15x magnification.

Images are shown on a 0.39" AMOLED display with 1920×1080 resolution, with seven selectable color palettes (White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, and Sepia) and a 20 mm eye relief. Photo and video capture with synchronized audio is supported, backed by 64 GB of internal storage, with the option to overlay a virtual reticle on recorded footage for realistic playback and review. Dual-band Wi-Fi (2.4 GHz/5 GHz) connects the device to the TargetIR app, while a built-in microphone and Bluetooth support additional connectivity.

Weighing 490 g and measuring 144×86×79 mm, the TB650S is built for balanced handling once mounted ahead of a riflescope. Power comes from a single, replaceable 18650 battery, providing up to 5 hours of operating time, while the IP68-rated housing and an operating range of -20°C to 50°C support reliable use across outdoor hunting conditions.
