ZEISS thermal imaging cameras offer 8 different color 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 color mode "rainbow" is ideal for identifying the smallest differences in temperature. In addition, four color 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 colors. "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.

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

When hunting, the most important thing is to know where an animal is. Sometimes animals are hard to spot because they are only partially visible. Detection mode highlights heat sources even more while reducing the cold background. This allows you to see animals behind trees and bushes better than before.

Hunting can be a very individual activity. When it comes to thermal imaging cameras, every hunter has their own personal preferences. Therefore, the new DTI's now offer the ability to select exactly which color 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.

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.

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. 

You can use the compass overlay to determine the direction of a target or get your own bearings. This can be especially helpful for stalking, or if you are out hunting with a companion and want to discuss different targets.

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