The Swarovski dG is the first long-range optical device to allow you to identify and document your sightings and share them with other people.

The full potential of the dG is unlocked when you link it to your smartphone. You need the SWAROVSKI OPTIK dG app to connect your dG to mobile devices. It also allows you to connect to apps like Merlin Bird ID and dG Mammals, which help you to identify and share your sightings. This app is available for all current smartphones from the App Store and Google Play.
