The Find My iPhone app on the iPad can also locate other devices, including iPhones, the iPod touch, a Mac, or other iPads.
To use it on a device, first make sure the Find My… option is enabled within the iCloud configuration under Settings. You’ll also need to be signed in with the same Apple account. On a Mac, turn on the Find My… option under System Preferences, iCloud and sign into the same Apple account.
The same options on www.icloud.com are also available within the app to help track down missing devices.
