Guide Nova N225 – Thermal Scope
Thermal Imaging Riflescope
The Guide Nova N225 is a compact, high-performance thermal scope designed for hunters who want serious capability without adding bulk to their rifle. Weighing just over 500g, it keeps your setup balanced and comfortable for long sessions in the field.
At its core is a 256×192 @12μm thermal sensor with excellent <25mK NETD sensitivity, allowing you to detect subtle heat differences even in poor weather or low-contrast environments.
With detection distance of 1000m, a smooth 50Hz refresh rate and recoil-activated photo/video recording, you’ll see fluid motion and automatically capture key moments before and after the shot.
