There are two ways to track dogs:

• Using a tracker directly connected to the smartphone. In this case, the tracker must be selected as a GPS signal in the smartphone. However, only the dog is recorded and not the person.
• Tracking (as the standard) the dog with a tracker and the person with the smartphone. The dog wears a GPS tracker which is read after the search. In the search, the dog's track can then be imported as GPX. Any tracker that provides data as GPX is suitable.
