Improved Focusing
The part of the image that is magnified in the picture-in-picture window is now highlighted with a focus frame. This makes it easier, for example, to track animals and make a decision for or against a shot more quickly.

Enhanced Camouflage and Battery-Saving Operation
The DTI 3’s LED Off feature provides better camouflage in the dark. The Auto Shutoff feature conserves battery power – the thermal imaging camera automatically shuts off after 60 minutes of inactivity.
- Note that the firmware update can only be carried out using the ZEISS Hunting App.
- Make sure that you have installed the latest version of the ZEISS Hunting App.
- Make sure that you activated mobile data before starting the ZEISS Hunting App.
- Do not switch off or operate the DTI 3/35 during the update process!
In some cases the Update will not run through automatically. If the DTI does not reconnect automatically follow these steps:
- After Step 1 of the Firmware update the DTI will restart and wireless will be switched off
- After the DTI has booted up again activate the wireless on your DTI again
- Make sure that your smartphone is again connected to the DTI wireless
- Return to the ZEISS Hunting App. The update process should resume automatically with step 2
- If the update process does not restart automatically, press the update button in the app again, the update should resume with step 2
