Our Observations

With Burris BTC50, the user has to long-press the on/off button for about 4 seconds until the manufacturer’s logo appears. We pressed the “UP” button (that has a zoom function) as soon as the logo appeared. As soon as the device responds, the ready-to-use timer stops. In this case, the device was ready to be used as soon as the image appeared. This means that the start-up and ready-to-use times are the same.

For the Burris BTC50 thermal device, we used the generic insertable batteries from Panasonic. The device supports 3V batteries, therefore we used the Panasonic CR123, 3V batteries. Please note that the results might vary if you use different ones. You can also use rechargeable batteries, as the charger comes with the device.

The device is easy to handle, and you can use the buttons even if you are wearing gloves. In my opinion, the on/off button could be a bit bigger, as it’s not too comfortable to press and hold. While testing it, I pressed the button multiple times, and my finger was a bit sore as it’s a bit harder to press. I didn’t like it very much, mostly because of that combination – small size and hard to press. It could also be a good thing, so you don’t accidentally press it in your pocket or bag.

Burris BTC50 has a Standby option, which is a remarkably useful battery-saving feature. If you wish to enter the Standby mode, you must hold the on/off button until the progress bar appears. Then you must release the button before the progress bar is full, and that is when the screen turns off and the device enters the Standby mode. To use the device again, you simply press any button, and the display instantly appears. The device is also instantly responsive to users’ actions.

To turn the Burris BTC50 off, the user must hold the on/off button, wait until the progress bar is filled up and the device turns off.
