The Calonox 2 View is Leica's handheld thermal. Its 640×480, 12 µm VOx detector is quoted at 40 mK and runs at 60 Hz behind a 42 mm F1.1 lens, giving a 2.5x base magnification, a 10.3° field of view and digital zoom in 1x, 2x, 3x, 4x and 8x steps to 20x. Leica quotes Johnson-criteria ranges for a 1.7 × 0.5 m target of 2,210 m acquisition, 770 m detection and 390 m identification; the 770 m figure is stored here as detection, which is a far more conservative convention than most makers use, so the numbers are not directly comparable with other brands.

It has a 1920×1080 OLED display, records 640×480 video and stills to 32 GB, and has Wi-Fi and Bluetooth. Two built-in 2,420 mAh cells give roughly 8–11 hours. The nitrogen-filled body is IP67 and weighs 657 g. Figures are from Leica's August 2025 datasheet, which revised the 2023 sheet's display, zoom and weight.

It suits buyers who want Leica optics and build for mixed and open ground.
