The Meddler's Belt was a time travel device worn about the waist. It's controls consisted of a dial for time displacement, a dial to compensate for spatial drift, and an activation button.
The belt was confiscated by Mike Callahan and he appeared to throw it into the fireplace at Callahan's Place. Actually he performed a sleight-of-hand trick to and kept the belt. It was later passed to Jake Stonebender and was stored at Mary's Place and brought to The Place in Key West where he stored it in a closet.
Zoey Berkowitz used it in an attempt to reassure herself that Erin was going to be safe after being kidnapped by Little Nuts. She failed to adjust the spatial dial and ended up floating in space. Erin rescued her and left the belt in space.
