ZEISS DTI 3/25 Thermal Imaging Monocular
The ZEISS DTI 3/25 is a compact thermal imaging monocular designed for fast, confident scanning at night, in low light, and through challenging outdoor conditions. With a wide field of view, 25mm f/1.0 objective lens, high-resolution LCOS display and ZEISS image processing, it is especially well suited to short-to-mid range observation in bush, woodland, scrub, paddocks and bait-site environments.
Built for hunters and outdoor users who need quick situational awareness, the DTI 3/25 combines a wide 26m field of view at 100m with a detection range of up to 880m. Its ergonomic, ambidextrous design and intuitive button layout make it easy to operate in the dark, even when wearing gloves.

Designed for Bush, Woodland and Close-Range Scanning
The DTI 3/25 is the wide-view model in the DTI 3 range. Its 25mm focal length gives a broader view than longer-lens thermal monoculars, helping you scan more area quickly and maintain awareness of your surroundings. This makes it a strong choice for dense New Zealand bush, forestry edges, stalking, pest control, bait-site observation and general night-time detection.
Smooth, Comfortable Viewing
A 50Hz display frame rate helps reduce image stutter and flicker while scanning. Combined with the high-resolution LCOS display, the DTI 3/25 gives a comfortable viewing experience for extended use in the field.
ZEISS Ergonomics
ZEISS designed the DTI series with a practical ambidextrous shape and a triangular button layout. The controls are easy to identify by touch, making operation more intuitive in darkness or cold conditions.
Photo, Video and App Connectivity
Capture photos and videos directly to the internal 15GB memory, or use Wi-Fi connectivity with the ZEISS Hunting App for livestreaming and media transfer. This makes it easy to document observations and review footage after use.
