### CurrentDevice

The _CurrentDevice_ object holds information about the device detected for the current visitor. The system identifies devices based on their user agent and retrieves the data about the capabilities of devices from the integrated 3rd party component [51degrees.mobi](http://51degrees.mobi/) or the _\~\App\_Data\CMSModules\DeviceProfile\devices.xml_ file.

You can take advantage of the _CurrentDevice_ object when defining conditions for device profiles and in general [macro expressions](https://docs.kentico.com/k8/macro-expressions.md).

The following list presents the properties of the **CurrentDevice** object. Most of the properties are only available in the [51degrees.mobi Premium data](https://docs.kentico.com/k8/developing-websites/developing-websites-for-mobile-devices/enabling-mobile-development.md#using-51degrees.mobi-device-data):

- You can access the device profile's system data through its properties, for example: _{% CurrentDeviceProfile.ProfilePreviewWidth %}_
- To directly get the device profile's name, use the following expression: _{% CurrentDeviceProfileName %}_
