Attaching it to keys
Due to small metal arcs up top, these tracking devices attach to mostly anything you want to keep an eye on -- say your keys, backpack, or camera bag. They're both lightweight, made out of black plastic, and small enough to hold in your hand. Both pieces run on a CR2032 lithium coin battery.
