Our Observations

With Leica Calonox Sight, the user has to long-press the on/off button for about 2 – 3 seconds. After some time, the manufacturer’s logo appears. When testing, the image appeared soon after, and the start-up timer stopped at approximately 11.96 seconds. We began pressing the ‘Menu’ button as soon as the image appeared, to demonstrate the ready-to-use time. When the device responded to the users’ actions, the second timer stopped, which was at approximately 15.52 seconds.

To turn off the device, the user must hold the power button. The countdown appears and the device turns off.

Leica Calonox Sight also has a Standby option, which is a useful battery-saving feature. If you wish to enter the Standby mode, you just press the on/off button. To use the device again, you must press the button again, and it becomes instantly responsive to users’ actions.

The device is a bit bulkier and heavier, but it’s still comfortable to use. It has a very nice and smooth design, and you can see the classic Leica features. You also get a case for the device, when you purchase it, which is a nice touch. It’s easy to handle and the buttons are comfortable to press, even if you’re wearing gloves.

Leica Calonox Sight has a built-in battery, you can charge it with the USB type C cable.
