The video explains in detail the operating principle of the ballistic calculator in Defender thermal systems.

The material covers:
– what a ballistic calculator is
– which input data are used for calculations (distance, profile, angle, temperature, and other factors)
– how the ballistic calculator interacts with the LRF and built-in sensors
– why the mere presence of ballistic functions does not guarantee an accurate result
– common mistakes when configuring ballistics

The material covers:
– the operating principle of dual focusing in thermal optics
– the differences between standard and dual focus
– the impact of dual focusing on image clarity, level of detail, and detection distance
– the practical value of this technology for hunting and professional use

The video provides a detailed explanation of how ballistics and the laser rangefinder (LRF) work in Defender thermal devices, and shows how these systems operate together as a single functional complex.

The material covers:
– what an LRF is in a thermal device and how distance measurement is performed
– how the ballistic calculator uses rangefinder data
– which parameters actually affect accuracy
– why proper integration of LRF and ballistics is more important than formal specification figures

The explanation is presented in a clear and technically accurate way, without promotional exaggeration, based on development practice and real-world use of Defender.

Analysis of the menu with the updated firmware from April 2025.

The Defender thermal imaging system is designed for professional use in challenging conditions, delivering high precision and reliability. With its advanced features, it serves as an indispensable tool hunting, and security applications. Key features include:

• High thermal sensitivity: The NETD parameter ≤20mk@300k ensures detailed and clear imaging, allowing for target detection even in low-light conditions.
• Flexible magnification: Optical and digital zoom ranging from 1.8x to 5.5x provides excellent image quality at various distances, enhancing observation and shooting accuracy.
• Durability in all conditions: The IP67 protection rating makes the device resistant to water, dust, and mechanical damage, while ensuring stable operation in temperatures from -25℃ to +55℃.
• Advanced features: A built-in ballistic calculator, a laser rangefinder with a 1200-meter range, and an auto-zeroing function improve the effectiveness of handling complex tasks. The CSFBC system and GEO dot technology offer additional tactical advantages.
• Extended battery life: The rechargeable battery enables up to 16 hours of continuous operation, making it ideal for prolonged missions.
• Data recording capabilities: The device includes 64 GB of internal memory for photo and video storage and supports quick data transfer via a Type-C port.
• Compact and user-friendly design: With dimensions of 379x100x110 mm, the system is easy to transport. Its standard Picatinny rail allows seamless integration with other accessories.

This system is an excellent choice for those who value efficiency and reliability in any environment.
