ZEISS DTI 3 Thermal Imaging Camera – Demo Unit
ZEISS precision engineering meets night hunting performance — the DTI 3 is the thermal imaging camera built by hunters, for hunters. This is a professionally tested demo unit offered at a reduced price, in full working condition, ideal for buyers who want flagship ZEISS thermal optics at exceptional value.
🔖 Demo Unit Notice: This product is a previously demonstrated ZEISS DTI 3 unit. It has been professionally handled and tested. Full functionality is confirmed. No accessories are missing unless stated in the listing. All sales of demo units are final.
Why Hunters Choose the ZEISS DTI 3
The ZEISS DTI 3 thermal imaging camera offers outstanding optical performance thanks to the perfect interaction of sensor, electronics, display, and eyepiece. The high-resolution HD-LCOS display delivers detailed images for reliable spotting — because the difference between a boar and the lead sow often lies in the details.
Developed by hunters, for hunters, the DTI 3 features ErgoControl design for intuitive one-handed operation — whether you’re left- or right-handed — so stalking in the darkness requires no distractions.
Key Features
384×288 Thermal Sensor — Sharp in Total Darkness
The ZEISS DTI 3 is equipped with a 17-micron 384×288 thermal sensor and a smooth 50Hz frame rate, delivering clear, flicker-free images in complete darkness, fog, rain, and heavy vegetation — conditions where standard optics fail entirely.
1,350-Yard Detection Range
Heat sources can be reliably detected over large distances of up to 1,235m (1,350yd), giving you a decisive long-range advantage in open fields, forests, and dense cover.
HD LCOS Display — 1280×960 Resolution
Imagery is displayed on a 1280×960 LCOS display that renders fine thermal detail with outstanding contrast — making it possible to identify species, read animal behavior, and make confident decisions in the field.
Four Color Palettes
The ZEISS DTI 3 offers four different shade palettes. “Black Hot” and “White Hot” provide high-contrast images, excellent for detecting, recognizing, and identifying targets. “Red Hot” allows for quick detection of heat signatures in densely vegetated environments. “Rainbow” mode is suitable for detecting smaller temperature differences.
Picture-in-Picture & Hot Tracking
The picture-in-picture function allows a simultaneous view of the zoomed image above the original image — helping you keep an eye on the animal even during sudden movements. In Hot Tracking mode, the warmest signature in the image is framed with a red square, making it easier to find and track heat signatures in densely vegetated areas.
Contrast Boost for Fog & High Humidity
Fog and high humidity significantly degrade the contrast of thermal imagers. In these situations, the Contrast Boost function can be activated to restore image clarity and maintain target visibility in challenging weather.
Precision Zoom in 0.5x Steps
The fine, gradual adjustment of the zoom in steps of 0.5 allows the perfect combination of magnification and detail recognition — so even the smallest details of observed animals can be quickly spotted, which is absolutely necessary for a safe approach in the dark.
10-Hour Battery Life
With an impressively long battery life of 10 hours, the DTI 3 will hold enough charge for two to four hunts — so you can stay in the field without worrying about power.
Live Streaming via ZEISS Hunting App
Photos and videos can be live streamed to smart devices. Using the ZEISS Hunting App, hunters can transfer data from the DTI 3 directly to a smartphone via wireless LAN, making it simple to save, manage, and share photos and videos.

Frequently Asked Questions
What does “Demo Unit” mean? A demo unit is a product that has been used for demonstration or display purposes. It has been professionally tested and confirmed to be in full working order. It may show minor cosmetic signs of handling but performs identically to a new unit.
What is the detection range of the ZEISS DTI 3? The ZEISS DTI 3/35 can detect a person-sized heat source at distances up to 1,235m (approximately 1,350 yards).
Does the ZEISS DTI 3 work in fog or rain? Yes. The Contrast Boost function is specifically designed to restore image quality in fog and high humidity environments, where standard thermal cameras lose contrast.
Can I stream video from the ZEISS DTI 3 to my phone? Yes. The DTI 3 connects to the ZEISS Hunting App via WiFi for live streaming, photo and video transfer, and remote management.
How long does the battery last? The ZEISS DTI 3 delivers up to 10 hours of continuous operation on a single Li-Ion charge — enough for two to four full hunting sessions.
Does it work for left-handed users? Yes. The ErgoControl design supports full one-handed operation for both left-handed and right-handed users.
