The Zeiss DTI 6/40 is a premium thermal imaging camera built for hunters who work the night shift. This handheld thermal device combines Zeiss's ZSIP Pro image processing with genuine glass optics and a high-resolution display to cut through darkness and thermal contrast challenges that trip up lesser gear. Whether you're glassing open country or verifying game in low-light conditions, the DTI 6/40 delivers the clarity and range you need to hunt confidently after dark.
At its core, the DTI 6/40 pairs a 640×480 sensor (12-micron pixel pitch) with a 40mm objective lens and 3x optical magnification, plus digital zoom up to 10x. That combination gives you a 2,000-meter detection range and a 19-meter field of view at 100 meters—enough reach for open-terrain hunting without sacrificing situational awareness. The 1024×768 AMOLED display renders thermal data sharp and bright even in pitch black, and scroll-wheel zoom control lets you fine-tune magnification on the fly without breaking your cheek weld.
Zeiss built the DTI 6/40 for real-world use: an ergonomic grip works for both left and right-handed shooters, controls fall naturally under your fingers even with gloves on, and the removable Li-Ion battery runs 6.5 hours per charge and swaps in seconds. The 4 preset scene modes and up to 5 user layouts mean you can dial in color palettes and brightness for your specific terrain. Pair it with the Zeiss Hunting App over Bluetooth, USB, or WiFi to offload footage, tweak settings, or live-stream your hunt directly to a phone. Built-in 16GB storage captures everything without reaching for external cards.
The package ships with a 40mm lens, neoprene strap, hard carrying case with shoulder strap, USB cable, cleaning cloth, and battery. Operating temperature range spans –20°C to +50°C, so it won't choke in cold-country hunts or desert heat.
