For an Unforgettable Experience. Detailed Images Even in Complete Darkness.
With the ZEISS DTI 3 GEN 2 you can easily locate and identify birds and other wildlife without disruptive light sources. But you can also get closer to nature during the daytime by identifying and observing hidden and camouflaged birds. With its ergonomic design and a high-resolution AMOLED display, it is ZEISS’ specialised solution that excels in any condition. With 1.7 × optical magnification and a range of 930m, the ZEISS DTI 3 / 25 GEN 2 provides the best conditions for a perfect overview at short distances. The wide field of view of 26 m and fine, gradual zoom settings combine magnification and detail recognition at a distance of 100m.

Improved Image Quality and Detailed Recognition
New, more powerful hardware enables improved image quality and pushes the boundaries of 384 x 288 sensors even further. The new 1,024 x 786 AMOLED display improves contrast and colour reproduction for a more detailed image with less background noise and sharper edges.

Extra Long Battery Life
With an impressively long battery life of 8 hours, the ZEISS DTI 3 GEN 2 holds enough charge for two to four birding trips. The Auto Shutoff feature conserves battery power: the DTI will automatically shut off after a freely selectable amount of time as long as you haven't interacted with the thermal imaging camera during this period.

Perfect Ergonomics
The DTI 3 GEN 2 family of thermal imaging cameras really stands out thanks to its unique ergonomics – the ErgoControl operating concept, with its intelligently positioned buttons, makes it easy to intuitively activate all of the device's functions. The perfect ergonomic design offers excellent handling in cold and dark conditions and ensures that both right-handed and left-handed users can operate the device comfortably.

High-Precision Zoom
It's often the details that make the difference: the fine, gradual zoom adjustment in increments of 0.5x offers the perfect combination of magnification and detail recognition. This means that nature observers can quickly recognize even small details, which is the key to accurately identifying them in the dark.

Three Observation Modes for Every Situation
Different environmental situations require a different instrument setting. The DTI 3 GEN 2 has three pre-programmed observation modes: universal, detect and fog. Detection mode, for example, highlights heat sources even more while reducing the cold background. This allows you to see animals behind trees and bushes better than before.

8 Different Colour Modes
ZEISS thermal imaging cameras offer 8 different colour modes, so you can choose the setting that best fits your needs. "Black hot" and "white hot" deliver images with a high level of contrast. When observing in areas with vast vegetation, "red hot" allows for a fast detection of heat sources. The colour mode "rainbow" is ideal for identifying the smallest differences in temperature. In addition, four colour modes have been redesigned to reduce the glare of the screen in a dark environment and reduce eye strain. "Red Hue" mode more easily adjusts your eyes to the darkness. "Dark Hue" is easier on your eyes by using low luminescence colours. "Green Hue" shows plenty of detail at low screen brightness, and "Night Eye" highlights the warmest areas of the thermal image in a pleasant sepia tone.

Movement Alert
The Movement Alert of the ZEISS DTI 3 GEN 2 and DTI 4 notifies you via an inconspicuous LED signal on top of the device or by activating the display when a heat source moves in the image.

High Frame Rate
The ZEISS DTI cameras featuring a display frame rate of 50 Hz. This refers to the number of times per second the monitor can redraw the screen. A higher display frame rate results in decreased flickering of the image, thereby reducing eye strain when using for several hours at a time.

Picture-in-Picture (PIP)
The picture-in-picture function of the ZEISS DTI allows overlying the zoomed image on the visual image. This feature helps to keep sight of the animal you are observing in zoom mode, even when it makes sudden movements.

Hot Tracking
In 'Hot Tracking' mode, the warmest source in the image is framed with a red square. Finding heat sources in densely overgrown areas and tracking them is therefore easier.

Thanks to the shortcuts available on the DTI 3 GEN 2 and DTI 4, you no longer need to open the menu to access most functions. The pre-programmed button combinations allow you to control numerous settings with just a few clicks, such as taking pictures and videos and switching between individual modes.

Compass Overlay
You can use the compass overlay to determine the direction of the observed bird or get your own bearings. This can be especially helpful for orientation, or if you are out birding in company and want to coordinate your different locations and observations.

Customizable Settings
Nature observation can be a very individual activity. When it comes to thermal imaging cameras, everyone has their own personal preferences. Therefore, the new DTI's now offer the ability to select exactly which colour modes are active and which are not, so you only must click through the ones you want to use. The same applies to the zoom level setting. Now you can limit the maximum zoom level to your liking.
