You have the option in the Whistle 3 app to either get a one-time location update for your pet's location or start a tracking session. Using the Track function will give you a location update every 90 seconds for 30 minutes, until you ask it to stop or when your pet comes within range of Wi-Fi. Alternatively, you can also select the Update Location option that hovers above your pet's icon on the map to get a one-time location update. Take note that you cannot Track if you are waiting for an Updated Location.
These location features are only available when your Whistle 3 is not within range of your Wi-Fi network. When the device is in Wi-Fi range, the app will let you know that your Whistle 3 is in power save mode.
