Image calibration without a screen saver
G-Zero’s shutter-free calibration provides a truly seamless viewing experience upon power-up, eliminating image judder that could lead to missed targets or critical moments during aiming. It also reduces shutter calibration noise, ensuring quiet, uninterrupted operation.
Note: The shutter module has been retained to ensure high image quality during power-on and under wide temperature fluctuations.

Even brighter image with Hyper-Light AI algorithm
The AI-based Hyper-Light algorithm, combined with a sensitive thermal sensor, allows you to see even distant objects clearly. This AI algorithm reduces image noise, enhances contrast, and highlights details, so animals or objects can be identified faster and more accurately, regardless of weather conditions.

Long operating time
For convenient use, the TB 2.0 series uses standard 18650 batteries, which are easy to replace and charge. Low power consumption ensures longer operating time, with a single battery lasting up to 5 hours. These standard 18650 batteries are also compatible with other GUIDE devices.

Precise operation
GUIDE TB650 2.0 is compatible with day scopes up to 15x magnification, ensuring accurate shooting and reliable operation in all conditions. The TB 2.0 series features exceptional accuracy (1,22 cm @ 100 m) for fast and accurate aiming.

64 GB memory and virtual viewfinder
GUIDE TB650 2.0 with 64GB internal memory for photos and videos. Recorded files can be viewed, shared and analyzed directly on the device, quickly evaluating results and improving skills. In addition, TB 2.0 attachments can superimpose a crosshair on recorded videos, simulating real-life situations and providing an authentic experience for video viewing and sharing.

Compact size and light weight
GUIDE TB650 2.0 weighs just 480-490g and measures 144 x 86 x 79mm. The compact design ensures comfortable use and easy handling even during long observations.
