Complete ApexVision S1 System Architecture
The Guide TULS is powered by Guide's next-generation thermal imaging solution. ApexVision redefines the infrared core of outdoor optics from the ground up - engineered for any condition, it delivers ultra-clear visuals with smooth, ghost-free motion, high-fidelity imaging and razor-sharp detail at long range.
LRF in Lens for Precision Shooting
The 1200m laser rangefinder is seamlessly integrated into the objective lens, minimizing the distance to the optical axis. This reduces parallax error and delivers highly accurate ranging in a more compact form.
Hyper-Light Algorithm, Ultra-Premium Visuals
Powered by next-generation sensors and the Hyper-Light algorithm, it delivers enhanced clarity, reduced noise, and optimized contrast, bringing out finer details with exceptional precision.
2560×2560 Display for Comfortable Viewing
Featuring a 1.03-inch AMOLED display with 2560×2560 resolution, the TU 3.0 Series delivers crisp, detailed visuals. With 60mm eye relief and AI-enhanced imaging, it ensures a more comfortable viewing experience, even during extended use.
Dual Battery Design, Worry-Free Power
A dual internal battery system, combined with a replaceable external battery, delivers up to 14 hours of continuous use. With support for hot-swappable 18650 batteries, you can extend runtime even further, keeping you powered for longer in the field.
Shutterless Design, Uninterrupted Visuals
Advanced Shutterless 3.0 technology eliminates image freezing and audible clicks, delivering smooth, real-time viewing without interruptions in the field.
Note: A shutter module is retained to maintain optimal image quality during startup and in extreme temperature conditions.
